David Andrews Internet Services Ltd provide a variety of search-engine optimisation services – including the optimisation of website code and content to improve a website’s rankings in Google and other search engines – and link-building / submission work to further boost a website’s ‘page rank’ with Google. This document deals with the latter of these services – i.e. the building up of links to your website from other, external websites – how it works and why it is so important…
The importance of ‘inbound’ links to your website
Most people know that the vast majority of visitors to any website originate from searches done on Google. As such, trying to manipulate Google’s search results pages to include your website on the first page has become a top priority for virtually any business with a website. Unfortunately Google treats its exact methods of ordering its search-results as one of the world’s most closely-guarded secrets – however, there are a number of bits of key information they do release publicly on how their ranking methods work – and how website owners can build their sites in such a way as to have the best shot at appearing at the top of its search-results listings.
The Google PageRank System
At the heart of how Google operates is its patented ‘PageRank’ technology. PageRank is the overall ‘score’ – out of ten – that Google gives a web page based on over 200, mainly secret, factors. By far the most-significant of these factors is the number of other websites that link to your website – so-called inbound links. It is important to note the difference between inbound and outbound links: An outbound link is a link on your site to another one – something that’s easily done by you or your webmaster, as it’s on your site, which you control. An inbound link is a link from a totally separate, external website that, when clicked, takes the user from that website on to yours. That is something only the other website owner can do – and something you have very little control over.
At the heart of Google’s PageRank technique is this rating based on the number of other websites linking to your site. The theory being that a site with many other links to it from other websites must be a useful, important, relevant website – otherwise no-one would link to it. A link to a website is seen as a ‘vote’ for the quality and usefulness of that website. Put simply, the more links pointing to your site, the more votes it has – and the better Google will treat it in the search results.
An example…
Take, as an example, the BBC website (www.bbc.co.uk). Time and again, when doing a search on Google for almost any subject, somewhere near the top will be the BBC website. Whether you search for ‘property prices’, ‘coal mining’, ‘gardening’… you will almost always find the BBC website featured in the magical top ten results. The BBC website has millions of pages of content and information on a variety of subjects and is seen as an ‘authority’ on most of them.
If I run a web design company – and see a news item on the BBC website talking about the importance of website usability testing – I might well want to link to that article from my own site, as it backs up what I often tell my clients. I put the link to the article on our website – and the BBC site has just had one ‘vote’ from me in the form of that link. Likewise, my next-door-neighbour, who is the head of the village gardening club, sees an article on how to treat black-spot in roses on the BBC gardening website. She thinks it’s useful to her members – so adds a link to the article from the gardening club website. Another vote for the usefulness of the BBC website…
And so this process continues on thousands of other websites across the internet. A useful, informative, authority website builds up many links to it across the web. Then, each month, along comes the Google ‘spider’ – an automated programme that scans virtually every website on the internet – indexing its content and detecting how many links exist to a particular website. It detects that the BBC site has 100,000 other sites linking to it. It must therefore be a great site – so it gets a page-rank of 9/10 – and suddenly every search you do on Google starts showing page from bbc.co.uk.
Getting a piece of this linking action for your own website
Of course, very few companies have the resources to develop a website like the BBC – so there aren’t many websites out there with a PageRank score of nine or 10 out of 10 that appear for virtually every search term in Google. The important thing is to start to develop a PageRank of your own, that gives you the same sort of advantage on a smaller scale. Build up more links to your site than your competitors, and your site will naturally drift above them in the search results pages. You don’t need 100,000 other sites linking to you – as few as 10 or 20 can have a radical effect, compared to a site with none or just a few. As a very general rule of thumb, if you can achieve a Google PageRank score of 4/10 or more, your site is off to a pretty good head-start in the search listings – and this sort of score is realistically achievable for most websites.
How do I know my website’s PageRank?
An essential tool for anyone with an interest in their website’s performance is the Google Toolbar. It’s a simple bit of software, provided free by Google. Download and install it on your machine and it sits at the top of Internet Explorer (or whichever browser you use) – enabling you to carry out a variety of Google-related activities directly from your computer and without needing to go directly to the Google website itself. The best part, is that it displays a PageRank ‘bar’ indicating the PageRank of whatever website you happen to be looking at at the time. Get the Google Toolbar from: http://toolbar.google.com (note how, when this document gets added to our own website, that will be another link – i.e. a vote – for the Google toolbar).
Quality over quantity
There is another factor Google throws in to the mix, just to complicate life further for webmasters (but consequently improve life for those doing searches – the whole point of its existence). Different websites – and types of websites – that link to yours can have a more positive effect than some others. It’s largely related to the relevance and quality of the ‘link neighbourhood’ of your website.
Imagine the example again of the BBC gardening website. The next-door-neighbour (Margaret) with the gardening club website, puts a link on her site to the BBC gardening site. Google is sophisticated enough to automatically ‘know’ the subject of one particular website – and how it relates to the subject of the site it links to. Google knows that Margaret’s site is about gardening – and it’s linking to the BBC site about gardening. Therefore, that counts as a ‘relevant’ link for the BBC site.
If I link to the BBC gardening site from our web design site – it’s still a vote for that site – but not quite as powerful a vote as Margaret’s one – because she knows about gardening, her site is about that subject – so her link is more valuable to the BBC site than mine. Likewise, if she – and five other people in her gardening club – put links on their websites to my web-design site, I’d be grateful, yes, and Google would see it favourably – but Google would look far more favourably upon one link to our site from the UK Web Designer Association – because it’s from a site on a more relevant subject to the content of our site. It’s not just about the number of links you build up, it’s about their relevance to the subject of your site too.
And it goes further…
And it’s not just relevance of the sites linking to yours either – another great factor is the PageRank – or perceived importance – of those sites with the links to yours. If you get a link to your website from one with an already high PageRank of its own, that site’s PageRank ‘rubs off’ on your site. Imagine the BBC decided to link to Margaret’s gardening club website. The BBC site has PageRank of eight or nine out of ten. For a site of that importance to link to Margaret’s site – to actually make a recommendation that its readers leave its own site to go and see Margaret’s; well, Margaret must have something pretty special on her site – and Google would promote it accordingly. She may go the whole year picking up links from her friends and colleague’s websites – all with PageRanks of one or two – and see comparatively slow improvement in her own site’s performance in the Google search listings. But shortly after getting linked to from the BBC site, her own site’s PageRank goes up a notch or two – and suddenly she’s showing up in the Google top ten for all sorts of searches. Visits to her site go up, club membership numbers rise… all as a result of the ‘vote’ her site got from a ‘big hitter’ website with a higher PageRank than her own.
The importance of ‘anchor text’
Another essential part of link-building is the matter of what the link to your website ‘says’. You are probably familiar with links on websites – very often appearing within text on a web page, usually a different colour and underlined to show the text has been made in to a ‘link’ which, if clicked, will take you to another web page or site. More often than not, it is the word ‘click here’ that is the link – i.e. the ‘anchor text’ and is what the link itself says. However, ‘click here’ – that most common of phrases on the web – is beginning to disappear, because of Google’s favouring of descriptive anchor text – that is, link text which describes and is relevant to the page that is being linked to.
Here is an example of a piece of text that might appear on a website linking to Margaret’s gardening club site. The text in blue is the ‘link’ bit, which would be the clickable part taking the user to her site…
…. Another excellent site we found with some useful information on treating
Black Spot in garden roses is the Bursledon village gardening club website.
Compare this with the following example…
…. Another excellent site we found with some useful information on treating
Black Spot in garden roses is the Bursledon village gardening club website.
Click here to visit the site
Note the descriptive anchor text in the first example, compared to the non-descript ‘click here to visit the site’ text in the second. If Margaret wants her website to appear high up in Google for the search terms ‘treating Black Spot’ and ‘gardening club website’ - she would be delighted to see that first example appear on another site – but less pleased with the second. If you can build your desired key words and phrases in to the link text itself, your search engine performance will be greatly enhanced. This also applies to the ‘title text’ that is coded in to the html of the link (and is seen in a yellow box that pops up when you hover your mouse over a link on a web page).
The flip-side of the link-building approach…
Anyone in the web industry knows all about the PageRank system and the importance of building inbound links – and as a result, a whole industry has grown around trying to influence Google by enhancing websites’ PageRank.
Google didn’t get where it is now by not keeping somewhat ahead of the game. They understand the general clamour around the web to build links and improve listings – and they know the techniques some people use to gain such links artificially. The mission of Google is to ensure that when a user types a search query in to its engine, the results it returns are relevant, useful, quality websites. If they are, that user will go back to it time and again – and won’t bother thinking about its lesser rivals – like Yahoo, MSN, Ask.com, etc. It therefore does not take kindly when an owner of a poor quality, irrelevant website suddenly has a high PageRank and starts showing up all over its listings – despite not containing information relevant to its users. But how did that poor website get its high PageRank in the first place?
Someone going on a link-building ‘spree’ – suddenly getting 50 new links in to their site in one day, by posting spam comments on a load of forum sites, paying for links on directory sites, setting up ‘bogus’ websites of their own purely for the purposes of linking to another… So-called ‘black hat’ techniques used to build up a link network falsely and give a website a PageRank it doesn’t really deserve. In theory, I could set up a gardening website this-evening and build 50 links in this manner tomorrow morning. Suddenly I’ve got a PageRank of 4/10 and I’m beating Margaret’s site in the search results hands-down, even though I know nothing about gardening, my site is hopelessly bad quality and contains a lot of misleading and made-up information…
When this sort of thing started happening, Google swiftly clamped down, building in mechanisms to its indexing to detect these techniques and penalise – even ban – websites in its listings. Any sort of un-natural sudden growth in the number of links to a site, or a lot of links appearing on other bad quality sites, can have a negative effect on PageRank and see your site suddenly disappear from the search results altogether. It is therefore important to be careful that any link-building attempts appear natural and ethical and do not have a negative effect on your site.
The death of the ‘link exchange’ programme
One final point to note, related to those above about negative link-building, is the increasingly futile nature of ‘link exchanges’. In the past, website owners would busily approach other site owners requesting links on their site in return for a reciprocal one on their own site. Both webmasters knew the benefit, so would happily ‘trade links’ between themselves. Of course, Google became wise to this – and has built in a further mechanism to its algorithms to dampen the effect of reciprocal linking.
If Google sees a link to my web design site appear on Margaret’s gardening site, that’s great – our site gets another notch on the PageRank score. But then, on visiting our site, Google sees a link back to Margaret’s site. It detects the ‘two way’ link, suspects we’ve colluded between ourselves over the garden fence to try to influence its rankings - and the effect of the linking is dampened. Note that the effect is not completely cancelled out – a reciprocal link is better than no link – just not as good as a link that is one-way – i.e. not returned.
Bringing this all together for your benefit
So how can you use this information – and this undoubted technique for improving website listings in Google to your site’s benefit? There’s no doubt about it, it’s a tough job to do. Getting other websites to link back to yours is hard enough – add to this the fact that you want similar sites to your own doing it - and for those sites to be high-quality – and to not link back to them in return for the favour… Oh, and you’ve got to ensure the rate at which the links build up is not ‘un-natural’ and that Google doesn’t suspect anything untoward going on – and that the anchor text is relevant and appropriate… To do this effectively can be a full-time, long-term job.
It’s important to start taking every opportunity possible to get links from other websites to yours. Techniques for doing this include offering a ‘testimonial’ to your suppliers in return for a link on their site to yours, finding ‘blogs’ on subjects relevant to your industry and leaving comments with a link to your site, posting on forum sites with a link to your site where possible, submitting to directories like Dmoz and Splut, simply requesting friends, family, colleagues and associates link to your website from theirs… The benefits of proper link-building are enormous and can result in a rapid rise in your website’s rankings in Google – particularly if you can beat your nearest competitors’ PageRank scores.
It’s important to note, however, that it is not completely clear cut. Very often you will find a PageRank 3 site way above a PageRank 6 site for a particular search term. Unfortunately this is the unpredictable nature of Google – and although link-popularity is well-known and Google releases the information in to the public domain, there are many other factors in its calculation - most that we will never know and can do nothing about. The fact that link popularity makes up about 60% of the factors influencing Google’s search results means it cannot be ignored by anyone serious about improving their site’s performance.
