LSI Relevance Density - Advanced SEO Using Latent Semantic Indexing

What is LSI?

The traditional singular keyword density percentage known well throughout the SEO community is quickly becoming less effective.

The search engine algorithms are getting much smarter, just look at how well they pick off duplicate content now compared with early 2006. However, making your content unique is just one part of what you need to be doing to get and maintain good Search Engine Rankings.

If your content is basic and only written around single keyword phrases there is a high chance your content will struggle to rank well.

This is due to a new Search Engine algorithm technology called 'LSI' or 'Latent Semantic Indexing'. What this new algorithm essentially does is it looks at your whole page (and website) from a relevance and thematic point of view.

I will let an expert in this field explain exactly what LSI is and how it effects you. Charles Heflin from SEO2020.com and author of 'The Master Plan' has been teaching about LSI for a while and I consider him to be at the forefront of these advanced SEO strategies. You can learn from him for free via his LSI SEO tutorials. Visit his website here to learn in detail about LSI and how you can use it to get an edge over the vast majority of your competition.

How DupeFree Pro Can Help You With LSI...

I will briefly explain here the on page keywords side of LSI so you can quickly understand how the 'LSI' function in DupeFree Pro can help you... but for full details on LSI do check out Charles Heflin's LSI tutorials.

The common keyword density calculation is based on the idea that the Search Engines look at the number of times a word or phrase ("golf shoes " for example) appears on a webpage in order to deem it relevant to that term and "rank" the page for it.

This is how the Search Engines used to work. Now they do things quite differently...

If you want to rank for a particular phrase (i.e. "golf shoes") you need to get terms that are "semantic" (mean the same as) with that phrase. However, this is not a simple as just looking up a thesaurus and throwing in all the words found there. Search results work differently because they are geared towards human trends.

Luckily Google provides a way to find the terms they consider semantic.

You can perform a "semantic" search at Google using the "~" (tilde) function by typing "~phrase" (without the quotes). Throughout the search results simply look for all the BOLD terms and collect them together. These are the terms that Google considers to be semantic to your phrase and they should be present on the page you are going to create. You have to perform a seperate tilde "~" search for each word in your keyword phrase.

Here is an example for the phrase "golf shoes"...

Click here to see the tilde search results for "~golf"
Click here to see the tilde search results for "~shoes"

These search results BOLD terms indicate you would need to include the following words/phrases in your "golf shoes" article:

Occasionally you may notice the search engines throw up some strange terms, but usually in one way or another they are related to your term. Perhaps not for your specific topic however (i.e. try a "~apple" search), so you must also use your own judgment as to which BOLD terms to include in your article.

The main point to note is that these terms are "Search Engine determined" synonyms NOT thesaurus determined. This is key.

What the Search Engines are looking for is "expert verbiage" and terms related to your topic throughout your content, not just one phrase stuffed everywhere with no real relevance to the rest of the content on the webpage or site.

As you can imagine, performing this for all your articles and keywords is yet another time consuming laborious process. So we have integrated an 'LSI' button in to DupeFree Pro to help automate collecting the LSI terms as well as analyzing your article for "LSI relevance density".

The DupeFree Pro 'LSI' Button...

The LSI button is located to the right of the keyword phrase entry box.

You can use this button to get all the LSI Search Engine determined synonyms for a keyword phrase in an instant and/or examine an article for the keyword densities of all the LSI Search Engine determined synonyms for a particular keyword phrase.

Below is an example of how to use the LSI function in DupeFree Pro...

First enter a keyword phrase in to the keyword phrase input box.

You can then optionally import or copy and paste an article in to the associated window if you want DupeFree Pro to examine the article with the LSI synonyms it will find for your keyword phrase.

With your keyword phrase entered press the 'LSI' button. DupeFree Pro will then take each word in your phrase and perform a tilde "~" search at Google.

DupeFree Pro will look for all of the BOLD terms in the top 100 results. We've found that there can sometimes be new bold terms appearing as low as the 90^th result so DupeFree Pro checks right up to the 100^th search result. Because DupeFree Pro does such a thorough search allow a little time if your phrase consist of many words.

When DupeFree Pro has completed the search it will display a small popup window containing a list of all the Search Engine determined synonyms found. If you placed an article in the article window prior to pressing the LSI button you will also get the number of times each synonym was found in your article and the density percentage for each.

This is an example popup window result:

When viewing this popup window you can still control the main DupeFree Pro interface below. This is very handy because if you had an article present in the article window DupeFree Pro will highlight all the LSI synonyms found in the article each with separate colours (shown in the previous screenshot above) and so you will want to be able to scroll the article window to view the spread of LSI synonyms.

The density percentage for each LSI synonym is a simple keyword density percentage calculation. Even though this is based on the old and now ineffective keyword density method it is still good information to know when comparing the densities of all the LSI synonyms at once.

Situated at the bottom right hand corner of the popup LSI window there is a 'Copy LSI Keyword List' button. Clicking this button will place all the LSI synonyms on the system clipboard so they can be pasted elsewhere such as Microsoft Word or Windows Notepad (this is shown in the previous screenshot).

This is very handy if you want to send these LSI synonym lists to your writers so they can include them when they rewrite your articles.

Or simply instruct your writer to use the LSI function in their own copy of DupeFree Pro and include all sensible synonyms returned by DupeFree Pro within the rewrites - you will no longer need to do any time consuming LSI keyword research!

I hope you can see the huge potential of this DupeFree Pro feature and how implementing LSI strategies together with DupeFree Pro can place you effortlessly ahead of your competition.
