Latent Semantic Indexing (LSI) And SEO

Indexing has always been considered a highly targeted science. Enter a search query into Google search and the pages that are displayed are generally optimized towards that exact word or term. However, in their continual battle to server the most relevant but most natural pages with genuinely useful information Google has injected latent semantic indexing (LSI) into its algorithms.

What Is LSI?

LSI is a unique indexing method that potentially takes Google search one step closer to becoming human in its way of thinking. If we were to manually search through web pages to find information related to a given search term we would be likely to generate our own results based on the theme of the site, rather than whether a word exists or doesn't exist on the page.

Why Search Engines Might Adopt Latent Semantic Indexing

The extremely rigid form of "keyword indexing" also meant that black hat SEO techniques were easier to implement. Search engines could be manipulated into ranking a site highly by using set formula. Originally, cramming a page with a particular keyword or set of keywords meant a site would rank highly for that search term. The proceeding set of algorithms ensured that your link profile played more of an important part than your keyword density. Reciprocal linking soon followed once again making it possible to manipulate the search engine spiders by exchanging links with tens, hundreds, or thousands of websites.

Reciprocal linking was soon beaten as Google and to a lesser extent Yahoo and MSN gave less credence to a reciprocal link as they did to a one-way inbound link. Latent Semantic Indexing is another, particularly powerful, method to try and make their result pages appear more natural with natural pages filled with natural content.

The Effects

The introduction of LSI has seen some dramatic changes in the search engine result pages already. Sites that had previously performed well because of an impressive link profile based on a single keyword have found their pages slip in the rankings. Other pages with a more diverse portfolio of inbound links are taking the lead with search terms for which they had not previously performed.

SEO is far from dead because of LSI, in fact if anything, it has probably increased the need for professional white-hat SEO on your website. The field of SEO, though, has almost certainly changed. Website content copywriting for Google's benefit is not merely made up of keyword density and keyword placement as it once was and link-building techniques will need to change to incorporate LSI algorithms but it can be done.

Writing Content For LSI

If optimizing solely for Google then a web page can, theoretically, be naturally written and naturally worded. When we write we instinctively include the appropriate keyword in our text. In order to avoid repetition (or keyword optimization, as it was once called) we would often alter some instances of these keywords for other words with the same or very similar meaning. We naturally include the plural or singular form of a keyword as well as different tenses and a number of different stems of that keyword. In the eyes of LSI algorithms this is all good news.

Looking At Your Link Profile

A link profile should no longer consist of thousands of links with the same anchor text (that of your primary keyword). There's no reason to panic if you already have this kind of profile. Instead you should look at relevant and similar terms and improve your link profile by gaining links using these as your anchor text.

What It Offers Web Searchers

From the point of view of web searchers, LSI offers some distinct advantages over its earlier form of indexing. For example, LSI recognizes that the word "engine" in "search engine optimization" is not related to searches for terms like "steam engine" or "locomotive engine" and is instead related to Internet marketing topics. In theory, LSI results give a much more accurate page of results as well as providing a broader range of pages still geared towards a particular topic.

Where Google Leads, Others Generally Follow

It is widely acknowledged that Google is the search engine at the forefront of latent semantic indexing. On the whole they try to generate results pages that are literally filled with genuine, useful results and LSI certainly provides another string in their bow. Yahoo and MSN, for now, seem more than happy to go along with keyword specific indexing although Yahoo are known to look at singular and plural keyword variations as well as keyword stemming when judging keyword density.

The Effect On Your Website

How it affects the individual Webmaster is dependent on how they go about promoting their site already. If the pages are filled with natural content including keywords and keyword alternatives, and the link profile is similarly diversified for a number of related keywords then the fact is it won't change very much. However, if all of your efforts have been concentrated, either on-page or off-page, with a single keyword then it's time to readdress the balance.

Choosing a Web Designer the Easy Way

Ads That Push the Envelope

Choosing a Web Designer

When you choose a web designer, there are many things that you need to be aware of and that need to be taken into consideration before you make a decision.

To some extent, the ability to work successfully with your web designer is sometime as important as their actual skill in being able to deliver the project.

A web designer that is skilled in what they do but is a pain to deal with can make the whole process frustrating and not worth the money being spent, especially if you have an emotional attachment to the project (which you should have being the one supplying the money and motivation)

That relationship can be worth a large proportion of the contract.

However, there are some key things you need to consider.

Be careful in what you get for your money. Some possible pitfalls you may want to check on:

Obviously what do you get for your money

What is included? Design, Content, Search Engine Submission, Search Engine Optimization (SEO), Graphic Design, Updates? You need to get these details so you can compare your quotes against each other. You also need to quantify some of these things in terms of quantity, hours, numbers search engines submitted to etc.

What are the ongoing costs?

All websites have ongoing costs. Web Hosting, Domain Names and updates are the main three. Make sure you know the total cost of your investment. Some companies offer lower up front costs to lock you into higher ongoing costs that end up costing you more. Some other things are SSL certificate costs, more bandwidth and web space.

How easy is it to incorporate your branding

Some template sites are hard to blend a logo or colours into them, be wary of template driven website companies, some of these people are skilled enough only to change the text on a template. Some designers design their sites from the ground up incorporating all of you design elements in their design. These companies offer the most flexibility.

How reliable is the services provided

With hosting and email, too much down time can make the whole experience unworkable. You don't want to have to change hosts after six months because your designer has provided you with a poor host. Some people rely heavily on email and these are the people that need to choose carefully so their business inst impacted.

What are the costs for making changes later on?

Updates and maintenance on your site is something that will eventually happen, even if you don't change the content frequently (see the Making Your Site Super Sticky Article for the benefits of this) you will eventually change some content and so you need to know what it will cost over a year.

Hidden costs

Make sure common things (like search engine submissions) are either not included or are an extra cost. Some key things can be omitted to keep the price down. Make sure you don't get sold short. An important one...is the web designer doing the job part time Are your web designers doing this as a full time job? Some designers are working during the day and then web designing at night. A lot of designers started out this way, but it can cause issues when you need something done and they don't do the job from 9-5.

If all these things check out then you have found someone who you can work with and provide you with a service that will get you your desired result.

Remember; choose a designer with the right skills, but also one you believe you can work with on an ongoing basis. Build a working relationship that will benefit you both and your web project will benefit as well.
