Sitemaps are an aspect of web design that has been around from the very beginning. The ideology is simple; create an accessible area of the website whereby users can navigate to any one area of your site architecture easily. A lot of web designers see these pages in the same way a builder would see four walls, a floor and a roof – they are part of the infrastructure and should not be ignored. While this is sound advice the reason and benefits for SEO may not be so transparent.

A sitemap can be a very powerful platform for SEO and I mean VERY powerful and yet it is so simple and often overlooked. Matt Cutts recently asked the question, which would he choose, an XML or HTML sitemap? He chose the HTML sitemap because both users and spiders can use the data. See the full video below:

Now the real benefit of having a good sitemap is the ability to make pages throughout a website accessible to the search engines. Most commonly great chunks of valuable content are hidden away in areas of a site which may seem to follow “SEO protocol”, in terms of URL structure and on page optimisation but for a search engine spider the content is hard to find.

An example of this would be on an e-commerce site whereby the structure follows homepage > category > sub category > products > content.  In the eyes of search engine spiders they have to crawl 4 levels before they can reach the juicy information/content and although Google are getting better at finding content (i.e. Caffeine) it can still help enormously by reducing the number of “obstacles” in their way. The theory is that by including a sitemap accessible from the homepage then Google will only have 1 “obstacle” to have to deal with before finding direct access to the rankable content.

Now to make a really effective sitemap for SEO it requires a little more methodology and architecture. It’s commonly thought that Google will take notice of at least 150 links on any one page before they start losing interest and move on to another area of a website. So for large websites that have thousands or even tens and thousands of pages it’s just not going to work including all your pages on one sitemap page.

So what’s the solution?

The most effective way to deal with high volume content websites is to create separate sitemaps for each website section. This deals with a few issues, firstly your main sitemap page will not go over the maximum number of links therefore all pages will be crawled and given value. Secondly the search engine spiders will still be able to access your deep content much easier than the normal way i.e. homepage > category etc.

The diagram below illustrates how a sitemap can be structured to ensure content can spidered.

For those of you thinking – how does this help increase my rankings? Well pages that were not previously indexed will now become listed therefore helping you rank for new terms. Acessibility really is the key here, internally and externally.

The final little treat for those of you that have taken the time to read the entire article; the anchor text used in a sitemap does seem to play an important part in terms of assigning value to those pages. This works on the same method as internal linking, assign keyword relevant descriptions to links in sitemaps and you will see better results than not doing so – tested and proved!

Ok guys, I have been link building for many years now but don’t always get the chance to practice the art as much as I’d like to, mainly due to my more strategic based role at my current job. Call me crazy but I do actually enjoy link building and I think you have to if you’re involved in the job, it’s a buzz to setup quality links for a client at absolutely no cost then watching the impact these links have on the rankings.

So the reason for my post is to share with you my observations from a recent batch of link building I completed. Most of you will probably already know what’s included but if you have a UK based client you may find this post has some value.

1. Domain Value – I have compiled a list of domain names based on results from link building and their direct effect on rankings for UK based sites:

Links from .ac.uk are similar to .edu links to our American friends and drive massive amounts of trust and authority. Links from .co.uk websites are also extremely valuable for link building in the UK, not only because of the localised domain but the content and language is usually more relevant. Surprising results show that .com links hold considerably less value than an equally matched .co.uk domain, when I say “less value” I mean less impact on UK search.

2. Anchor Text – A year or two ago I would have said keywords in anchor text is a must but I have to say there’s less weight on this factor than their use to be in the UK. I realise that Seomoz recently released the 2009 ranking factors but in the UK brand terms in links still deliver a very healthy amount of link juice which I’ve seen massive rankings boosts from. Although I must say this is based on domains no younger than 12 months old, any younger than that there would probably be a different outcome.

3. Negotiations – I’m going to start sounding rather old now but “back in the day” emailing webmasters for links worked well, generally because SEO was not really as widely known. However there is a misconception that this tactic will not work now due to the increase in web knowledge from website owners. Well let me tell you this is still the best method to build links anywhere, out of 40 emails sent to prospective sites I setup 15 links for free to sites including .gov and .ac.uk with an average PR of 4. Of course it’s all about finding the right sites but that’s the fun no?

4. Impact – This is kind of a gray area in the link building world, how long will it take my new shiny link to boost my rankings? Well usually it depends on when the bots crawl the link and add the update to the index, a good indicator of this was recently announced whereby it was mentioned Page Rank is a measure that is used to determine how often Google will visit a site. Essentially sites with a higher page rank will pass value to you quicker.

5. Directories – You can still get some great positive movement in rankings by identifying directories which are based or targeted for the UK. Firstly the domains are mostly .co.uk which provide good link juice and the content is often localised (which can bring in added benefits for local search). Admittedly the directories that hold the most value in the UK often have a review price but there are other gems out there if you look properly.
