Latent Semantic Indexing. All of the Search Engines have invested in this technology and if they are not using it now, they will be soon.
The definition for
Latent semantic analysis (LSA) is a technique in natural language processing, in particular in vectorial semantics, patented in 1988 [1] by Scott Deerwester, Susan Dumais, George Furnas, Richard Harshman, Thomas Landauer, Karen Lochbaum and Lynn Streeter. In the context of its application to information retrieval, it is sometimes called latent semantic indexing (
LSA uses a term-document matrix which describes the occurrences of terms in documents; it is a sparse matrix whose rows correspond to documents and whose columns correspond to terms, typically stemmed words that appear in the documents. A typical example of the weighting of the elements of the matrix is tf-idf (term frequency-inverse document frequency): the element of the matrix is proportional to the number of times the terms appear in each document, where rare terms are up weighted to reflect their relative importance.
This matrix is common to standard semantic models as well (though it is not necessarily explicitly expressed as a matrix, since the mathematical properties of matrix are not always used).
What does all of this mean in English? Well, it’s pretty simple for the human brain to comprehend, but complicated to approximate mathematically. Essentially, what all of this means for the average site builder is that instead of thinking exclusively in terms of niches and whole pages based on single keywords, you should think more about organizing whole thematic relationships in contextual hierarchies sometimes called inverted pyramids, Silos or Matrices? Pages and sites should contain thematically related words and subdivisions rather than being completely keyword centric and the linking in general should flow from general to specific.
Thematic Keyword Technique – Manual Approach
It seems everyone and their brother sells or promotes a keyword tool. The good news is that the best one is
The best keywords on the internet come not from WordTracker, Keyword Discovery, Overture or the army of keyword tools that get their words from one or all of those sources. The best keywords come from GOOGLE. How do I know they are the best? Google is the most used Search Engine on the internet. Consequently, their source of keywords is vast.
If you let them, Google will provide all the tools you need to make money on the internet for
Let me show you how to make a killer list of thematically related words with the Google Adwords Keywords Tool External.
First, copy and paste the following URL into the address bar of your browser:
https://adwords.google.com/select/KeywordToolExternal
The page will open to the following:
2. Put in your keyword – use synonyms and click get more keywords – let’s do fishing for an example.
3. At the bottom of the returned list, click add all. The keywords are then transported over to the right side of the page and you have all the words that Google provides for that specific keyword phrase.
4. Pull up another web page window and go to google.com. Do a search for your main theme and just leave that page open showing all the results.
5. Now go back to the Google Keyword Tool and select Site-Related Keywords and your browser should display the following:
6. Take the first URL from your Google search (in this case www.fishing.com) and put it into the tool and click get keywords.
You should get a list of words thematically grouped by the words in the Showing keywords grouped by these terms area below:
Continue down the page and you will see the groups and words like this:
Send all the keywords over to the right side of the page and repeat the process with all of the URLs on the first and second pages of Google. Then, edit, filter and hand select your words as needed and you’re done.
Take a look at all the words that are returned by Google and think about what is really going on here. You are essentially getting Google to give you all the words they determine are thematically relevant to the content on each of the sites on the first and second pages of results. It is not simply a drill down to the useless and obscure. It is relevance by thematic relationship and these word sets contain the perfect building blocks for their Latent Semantic Indexing algorithms. If you create sites with these word sets, provide good content, properly construct your site and linking architectures and execute some well thought out promotion, your sites should rank very well.
The part that may be somewhat hidden or elude some of you is that in the process of extracting related terms, Google also returns thematic subdivisions that can form the basis for a fully themed website. You may have to pick and choose a bit, but I think you get the basic idea. You can also get a good idea of how to section your web site by using a tilde (~) in front of a Google search term inside the search box. Those features return all the words that are related to the original word and they can also be used as the basis to formulate web site sections or subdivisions for proper site theming.
Another much simpler way to do all of this plus a lot more is to make a small investment in NicheBot. $1 gets you started with NicheBot and as little as $9.97 per month gives you access to the best (and least expensive) keyword tool on the market. Did you read the part where I said you can get started for a measly dollar bill?
If you’ve done any sort of keyword research, then I’m sure you are used to seeing a keyword and a count number that represents the search demand.
It’s sort of one-dimensional. Know what I mean?
What if I told you that you could look deeper into a keyword and look at monthly trends of a keyword.
That would be much more insightful, now wouldn’t it?
Well, I would like to show you exactly how you can pick winning keywords every single time — and you can literally do this blindfolded. Well, not really, but close enough.

Awesome information here about keyword search.
You are a wealth of information. Thank you!
I use Google keyword tool too, but never use the site related option. Thanks for the tips and for remaining me.
Thanks for giving some very useful stuffs concerning how to identify relevant keywords. I tried to sign up for the $1 offer at http://ez-money-online.com/nichebot.html but the sign up page didn’t respond when I tried to make a selection for “countries”. I had emailed Nichebot. If this continues to happen you would be losing your affiliate commission since your visitors would try to access its main page.
I manage to secure a position among the top 50 for a high competitive keyword of “debt free” by Google for my http://crushbadcredit.com and “cheap ebooks” and “cheap software” for my http://digitalproductscenter.com
The information I had gathered at you blog would surely make me a better person in researching relevant keyword.
Awesome post suz, thats my major problem KW research, i look forwards to using your step by step method
Hey thanks! It never dawned on my thick scull to use google’s tool this way. It should actually simplify how I get effective keywords.
This is getting a bit more subjective, but I much prefer the Zune Marketplace. The interface is colorful, has more flair, and some cool features like ‘Mixview’ that let you quickly see related albums, songs, or other users related to what you’re listening to. Clicking on one of those will center on that item, and another set of “neighbors” will come into view, allowing you to navigate around exploring by similar artists, songs, or users. Speaking of users, the Zune “Social” is also great fun, letting you find others with shared tastes and becoming friends with them. You then can listen to a playlist created based on an amalgamation of what all your friends are listening to, which is also enjoyable. Those concerned with privacy will be relieved to know you can prevent the public from seeing your personal listening habits if you so choose.

One day. Xiao Ming another class …. a sudden “rush”() a cry,sitting next to a small U.S. scolded and said: Xiao-Ming Ah ~ if you could not make a noise!
Very cool tips for keywords.
Great blog.
