search engine optamization for blogs SEO


Search Engine Optimization is something that makes many blogger’s heads spin – I know this because every time I write an SEO article I get comments from bloggers telling me that its too big a topic and that they’d rather just write ‘quality content’.
Whilst I’ll never argue that quality content should be anything but a first priority in blogging, the fact is that there are many millions of pages of great writing languishing around at the bottom of search engines results pages that deserve to be read by many but which rarely see the light of day because their authors have failed to understand that just a few simple tweaks in the writing process could see them ranking considerably higher.
So it’s time for another series – this time on Search Engine Optimization for Blogs!
People often ask me ‘how do I get ranked number one in (((insert favourite search engine here)))?
My answer usually starts with – ‘I don’t really know what I’m talking about….but….’
You see whilst some of my blogs rank very highly on different search engines – I often don’t really know why. Much of what I do is educated guessing and experimentation. I do read a lot of other people’s advice on the topic, but the more I read the more I realize that I’m not alone in my guess work – virtually every article I read is a ‘best guess’ of some kind.
My main advice to people wanting to optimize their blogs for Search Engines is to keep it simple. Start with quality content on a specific topic and then tweak it using the best current advice going around.
When I think about SEO for my blogs I tend to divide the things I focus upon into two parts – offsiteand onsite search engine optimization techniques. Offsite techniques are more about what others do on their websites in linking to you, onsite techniques you have more control over as you write.

Off Site SEO Techniques

Apply to be a Chitika Publisher!
Off site SEO techniques are as the name suggests factors from outside the site itself (ie from other sites) that impact the blog’s ranking in search engines. Many of these factors are outside the blogger’s control – however they are useful to know. The most obvious and probably most powerful offsite factor are Inbound Links (something I’ve already referred to above).
It is generally agreed that the links that point to a website are one of the most powerful way of climbing Search Engines results pages (in fact many argue it is THE most important factor). – To put it most simply – every link to your site is seen by the search engines as being a vote of confidence in your site.
Ideally Speaking – The best inbound links have three main qualities to them:
  1. they are from higher ranked sites than your own
  2. they are relevant to the topic you are writing about
  3. they link to you using relevant keywords to your page
Whilst you may not have complete control over who links to you these are the types of links that you should be dreaming of.
How to generate quality inbound Links?
Of course whilst most of us know this it doesn’t make getting such links any easier – its in the hands of others in many cases. So how do you get such links?
  • Quality Content – There are all kinds of link generating systems out there but in my opinion the best way to get links to your blog is to write quality content that people will want to read. You can solicit links with others or sign up for different link building programs or even buy text links on other sites but the cheapest and probably safest approach is to build inbound links in a natural organic way as others link to your quality content.
  • Notify Relevant Bloggers of your content – Whilst I don’t advocate spamming other bloggers and asking for links – I would recommend that if you write a quality post on a topic that you know will interest another blogger that it might be worth shooting them a short and polite email letting them know of your post. Don’t be offended if they don’t link up, but you might just find that they do and that in addition to the direct traffic that the link generates that it helps build your own page rank in the search engines (more on letting other bloggers know of your posts here).
  • Directories – Another way to generating inbound links is to submit your links to directories. I know of webmasters who swear by the benefits of such a strategy – the first thing that they do when starting a new site is to do the rounds of directories – submitting links to key pages with appropriate keywords in the links. There are loads of directories out there – many of which offer a free submission. Ari Paparo has compiled a list of blog directories that you might want to start with.
  • Inter-link your Blogs – Increasingly bloggers are starting or joining blog networks to enjoy the benefits of multiple sites and writers working together. One of the advantages of networks of sites is that they usually link to one another. In doing so you have complete control over how your sites are linked to from multiple domains. It is worth noting that you should be careful with this approach – if all your sites are hosted on the one server many think that Search Engines will work out what you’re doing and the impact will be lessened.
  • Buy Links – Many professional web masters have a budget to purchase links from other highly ranked and and relevant sites. I won’t go into this too much here but you might like to read more about it in my recent post On Buying Text Links. update: I’d encourage anyone wanting to buy links to think very carefully about this. Google have been cracking down on sites that use this practice. They can’t catch everyone but some have been caught and seem to have been penalized for doing it.
  • Swap Links – Similarly many bloggers swap links with other bloggers. Sometimes this happens pretty naturally (you see someone linking to you so you link back) but in many cases the links are strategic ones and formally arranged between site owners. I get daily requests for such reciprocal links (I rarely act on them). Whilst there is some benefit in such link swapping I would again advise caution here as many SEO experts believe that the search engines have methods for tracking such strategies and devaluing the links. Some try to get around this by doing indirect or triangulated links. ie instead of site A and B doign a direct swap they involve other sites. So A links to C in exchange for D (also owned by C) linking to B (also owned by A) – makes your head hurt doesn’t it!?! There are also a variety of systems around that say they’ll take care of such interlinking for you – I know many who use Digital Point’s Free C0-Op Advertising system. Personally I tend to avoid such schemes and have a policy of linking to sites I think are valuable to my readers. If they link back then so be it.

On Site SEO Techniques
Having looked at Off site Search Engine Optimization Techniques I’ll now turn my attention to examining some of the factors you might like to keep in mind as you build your blog – (or Onsite techniques – things you do on your blog that help build a higher ranking). As with all SEO techniques there are many of these and a lot of speculation around all of them so let me touch on as many as I can:
1. Keyword Rich Content – identify a few keywords for your article that you’re hoping will get indexed highly by Google. Don’t pick too many but consider the questions
  • How do I want people to find this post in Search Engines?
  • What will they type into Google if they want information on the topic you’re writing?
  • How would I find information on this topic in the Search Engines?
  • What results come up when I do plug these keywords into Google?
  • What other keywords are other sites using?
The answer to these questions will give you a hint as to what words you’ll want to see repeated throughout your article a number of times.
These keywords will need to be the most common words used in your article. Use them in some or all of the following ways:
  • Keywords in post and page titles (read my post on using keywords in titles)
  • Keywords in URL of page (blog herald wrote on this a while back)
  • Keywords in outbound links (read this article on the pros and cons of outbound links)
  • Keywords in bold tags (try do it at least once)
  • Keywords in heading tags (there is debate over exactly how to use them but it’s generally accepted that h1 tags are important and that h2, h3, h4 etc tags also have an impact. Having said that I’ve seen some pages rank very well in search engines without using heading tags. There are many tutorials online about heading tags – here’s one.)
  • Keywords in image alt tags (here’s how)
  • Keywords in the general throughout the text of your post – but especially early on in the first few sentences
  • Keywords in meta tags (they seem to be less valuable these days but many still believe they are useful with some search engines – here’s a Guide to meta tags)
Of course you can go over the top with keywords in posts and let it destroy your content – but if it fits with what you’ve written tweak it to include the words you are targeting a couple of extra times. Most SEO experts recommend getting your keyword density up to between 5-20% – I think 20% is probably bordering on massacring your content.
One last word of warning and disclaimer on keyword rich content (because I can just hear the comments on this post already) – don’t sacrifice your readers experience of your site just for the sake of SEO. Yes keyword density can be important in climbing the search engine rankings – but more important is that your content and design are user friendly and helpful to readers. There is nothing worse than a site that is stuffed with keywords – these sites come off as cheap, nasty and spammy – don’t fall for the temptation.
2. Themed sites - One of the growing theories of SEO is that you are more likely to rank well if you have a substantial amount of pages on a similar theme. ie a niche topic blog will probably rank higher than a general one that covers many topics. Build a blog with over 200 pages of content on the same theme and you’ll increase your chances of ranking well as SEs will see you as an authority on the topic. The take home advice here is to keep to some kind of a topic/niche/theme for your blog. It is also probably another argument for categories and tagging posts that relate together strongly.
3. Site Design – Search Engines like well laid out, well coded and easily to navigate sites. Make sure your pages validate (I need to work more on this) and that they are viewable on all major browsers. Search Engines don’t tend to like too much Flash, Frames or Java Script in your site – keep it simple and clean and their robots will index your site a lot faster and more accurately. Also try to keep your blog free from dead links (a challenge for those of us with older blogs with big archives).
4. Interlink your Site – The way Search Engines index your blog is to send little robot crawlers to your site to track what you’ve written and follow the links. Make it easier for them to get around your blog by using internal linking wisely. Most SEO experts recommend that you provide some sort of Site Map that means every page on your blog is just a link or two away from every other one. One way to do this for bloggers is to make sure that your category pages are in your sidebars as I do in this blog. Also make sure every page links back to your main page and any other important pages on your site. If you’re writing on a topic you’ve previously written about consider linking to what you’ve written before or use a ‘other relevant posts’ feature at the base of your article. You’ll see in my menus at the top of the page a number of my key categories and articles. One of the impacts of having them highlighted in this way is that they have become some of the most highly ranked pages on ProBlogger simply because they are linked to from every page of this blog.
5. Update regularly – The more you update your blog the more often Search Engines will send their crawlers to your site to index it. This will mean your new articles could appear in the index within days or even hours rather than weeks. This is a natural benefit of blogging – make the most of it!
6. Outbound Links – There is debate over how SEs treat outbound links from your blog. I’m in the camp who believe that relevant outbound links enhance your site’s ranking in search engines. I always link out to quality relevant sites that I think my readers will find useful and have a little anecdotal evidence that seems to support the theory that this is healthy for the way SEs index you (check out Waynes article on the topic for more info). Linking to sites outside your own blog does mean you end up sending traffic away from your blog so you need to count the cost of such a strategy. Note that you should always try to link to reputable and relevant sites to your own page. Also keep in mind that too many outbound could have detrimental impact upon your blog. Like in most things in SEO – moderation is the key.
7. Choose your domain name wisely – there are numerous factors to keep in mind when selecting a domain name. For one you might like to include your keyword in it if possible. Secondly you should do a little research to see if someone else has previously used the domain. This could have both positive and negative impact. If it was a quality site with inbound links you might reap some benefits but if it was a banned spam site you could still be banned from Google for a long time. One service you might want to use to check expired domains is Way Back Machine at Archive.org.
8. Register your Domain for a Lengthy Period – a recent patent by Google indicates that it now looks at the length of your domain’s registration in ranking it. It does this because many spam sites have short registrations and a longer one indicates that you’re building a site with substance and are in it for the long haul.
9. One topic per post – the more tightly focused the theme of a page the better when Search Engines come to rank it. Sometimes you might find yourself writing long posts that end up covering a number of different topics. They might relate loosely but if search engine ranking is what you’re after it could be better to break up your post into smaller more focused pieces.
10. Write optimal length posts – there is some thought going around the Search Engine Optimization community that pages that are too short can get passed over for high rankings. I try to keep posts at least 250 words. Of course there are some posts on my blogs that are shorter, but if I’m writing a post that I want to rank well I try to give it some meatiness in terms of length. On the other hand don’t make it too long either – because in doing so you make it difficult to keep your keyword density up and could end up with a less tightly focused page. Research also shows that longer articles can have a pretty steep drop off rate in readers after the text gets below the ‘fold’ or to the end of the first screen of article .
11. Avoid Duplicate content – Google warns publishers in its guidelines about having the same content on multiple pages. This goes for both multiple pages that you own but also pages that others own. This is because a tactic of spammers is often to reproduce content on many pages and/or to steel content from other sites. There is some debate over what duplicate content does and doesn’t include (for instance many bloggers use ‘free articles’ as content on their blogs – these articles often appear on hundreds and even thousands of other sites around the web and to me could be seen as duplicate content) – my advice is to be very careful about how many places your content appears. I do republish occasional posts (or parts of them) but try not to do this too much and attempt to add elements that are unique on each occasion that the posts are republished).
12. Ping – services like Pingomatic (there are numerous others too) will ping a variety of websites for you to notify them that you’ve updated. In doing so you’ll also be letting search engines know that you’ve updated which will trigger their robots to come visit your blog. I’d also suggest pinging Google’s blog search tool.
13. Submit your RSS to MyYahoo – submitting your RSS feed to MyYahoo seems to help with getting indexed on Yahoo. Read more about this at Getting Yahoo Traffic for your Blog. Some also think that doing the same thing to Google’s Personalised pages could have a similar impact.
14. Quantities of Content – I always get into trouble when I write about having lots of content – but I think its true that bigger sites tend to rank better than smaller sites – whilst it is possible to rank highly with a small site – it’s probably not the norm.. Search Engines will see your site as more comprehensive the more content you have. You also better your odds of being found in Search Engines if you have more pages. By no means am I saying just to put up random junk content – be careful about this – rather work at building a comprehensive and large site over time.
15. Submit to Search Engines – You can do all the best onsite SEO strategies in the world and still get no where because the Search Engines have not found you to start with. Each search engine has a way of letting it know about your site – submit your URL to be included in the index. Please note that this takes time and perhaps a quicker and more effective way is to get linked to by a site already indexed by the search engine. I’ve written a post about his previously at how to get indexed by Google.
You might also like to tryout some of the services around that offer to submit your sites to search engines for you – I’d be wary of paying for this sort of service though. I never have and seem to do ok.
Again I will reinforce – the above techniques come out of my own experience and from the things I’ve learnt from others. I am not an SEO expert but find that if you keep the above in mind you can do reasonably well. Don’t become obsessed by SEO – if you do you run the risk of forgetting about your reader, forgetting to write quality content and you could find yourself getting into some dodgy SEO tactics that could get you banned from the Search Engines You’re trying to get listed in.
I’ll finish here by adding that SEO can take time – so be patient. After 2.5 years of blogging I’ve managed to build my blogs page ranks and SERPs but it did not happen over night. Sometimes it seems that no matter what you do nothing works – it may be that the words you’re wanting to target are actually a heavily targeted segment of the internet (consider changing your approach) – or it may just be that there is some unknowable glitch with the SE you are targeting – its a fickle game and one that I’d recommend you don’t rely on alone. So yes work on your SEO but also consider the many other methods around to find readers for your blog. You might like to read my Finding Readers for your Blog Series as a starting point.

NSF grants funds research into training robots to work with humans-information about nfs


Apply to be a Chitika Publisher!
What if robots and humans, working together, were able to perform tasks in surgery and manufacturing that neither can do alone?
That’s the question driving new research by UC Berkeley robotics experts Ken Goldberg and Pieter Abbeel and colleagues from four other universities, who were awarded a $3.5 million grant from the National Science Foundation.
Their work is part of the first $50 million in funding for the National Robotics Initiative, announced in 2011 with the goal of exploring how robots can enhance the work of humans rather than replacing them.
“The emerging generation of robots are more aware than oblivious, more social than solitary, and more like companions than tools,” says Goldberg, a professor in the departments of Industrial Engineering and Operations Research and  Electrical Engineering and Computer Sciences.
The four-year project, a collaboration of experts at Berkeley, Stanford, Johns Hopkins, UC Santa Cruz and the University of Washington, will focus on ways that robots can be trained by humans to perform “multilateral manipulation,” with one or more humans providing perception and adaptability and robots providing speed, precision, accuracy and dexterity, as the researchers described it in their grant application.

In surgery, for example, a human-robot system could mean an extra set of “hands” for retraction or suturing for a doctor focusing on more complex procedures. The concept envisions something quite different from tele-surgery, where a remote surgeon controls robotic equipment directly; the next generation of robots would function autonomously, but with training and supervision by humans and reliance on algorithms and data libraries compiled by humans.
In manufacturing, such human-robot systems could learn to handle tasks such as threading wires or cables, or aligning gaskets. In households, they could wrap packages or fold laundry.

All of these examples revolve around the idea of teaching a robot to properly handle objects whose size and shape can be variable, because they’re made of malleable materials.  Examples include strings, wires, sheets, and cushions and organs.
Abbeel, an assistant professor in EECS, has done groundbreaking work in this area; he programmed a robot to pick up, recognize and fold towels crumpled in a random pile. A video shows the robot in action.
“Robotics is at an inflection point,” says Goldberg, pointing to some 5 million household robots, 10,000 military robots and 2,000 surgical robots adopted over the past decade. An emerging new paradigm is “cloud robotics,” in which robots no longer have to be self-contained but instead are designed to tap vast global stores of information, parallel computing power, data sharing and open-source programming.
Berkeley is a leading center for robot learning and cloud robotics, notes Goldberg. With researchers at Google, he recently submitted a paper on a robot trained to recognize and grasp objects using Google Goggles, a “crowd-sourced” online database of images of objects.

computer projects to seek early signs of dementia-new technology in computet

The first signs of mental decline could be recognised by computer to enable people to refer themselves for medical care and support. Currently, only half of people with dementia ever receive a diagnosis so researchers are trying to find new ways to persuade people to seek help. Lancaster University is leading a project to see if computer interaction can offer new opportunities for self-referral.

Now, smartphones to act as secure and versatile keys


Apply to be a Chitika Publisher!


Researchers have developed a new software that makes the technology of opening car and home doors using smartphone apps more secure and versatile.
Researchers from the Fraunhofer Institute for Secure Information Technology SIT in Darmstadt, Germany, will be demonstrating their ShareKey software, a solution to
popularise the method.
"In essence, ShareKey offers two new functions: users can issue digital keys remotely and assign these keys certain user permissions. For instance, I can grant the building
superintendent access to my apartment for a short period so that he can open the door for the gas meter to be read while I'm at work," said Alexandra Dmitrienko from the SIT.
"The solution is built around modern security technologies and can be easily integrated into existing access control systems," Dmitrienko said in a statement. ShareKey sends electronic keys directly to the user's mobile phone, in the form of a QR code attached to an e-mail or MMS.
"Recently, users of parcel stations have fallen victim to phishing attacks. Equally, hackers continue to target their efforts on smartphones. In light of this, the big challenge was to protect the electronic keys without compromising the intuitive operation of such devices," said Dmitrienko.
ShareKey works using the Near Field Communication (NFC) transmission standard, which allows data to be exchanged wirelessly over short ranges of up to a few centimeters.
"To open a door, all you need to do is hold your mobile phone close to the lock," said Dmitrienko.


NFC interface and door locks only operate within a narrow bandwidth and have limited computing power.
Scientists at the SIT have equipped ShareKey with particularly resource-efficient communication protocols.
Electronic keys are reliably protected on the smartphone from malware and unauthorised access.
This is achieved by leveraging advanced technologies which keep sensitive data on the smartphone separate from other data and apps.
Communication between the mobile phone and a central server is protected by established security protocols.
Smartphones are becoming a WONDER machine that has become 'ALL IN ONE'-it has made so many electronic goods outdated!
"And even if this communication is hacked into, it's impossible for unauthorised people to gain access to the digital key," he said.
