I have done extensive experiments on this particular topic and read through experts' opinions. Here is the sum total of what I have spent my time on. You need to refocus your webpage content to what the search engine (Google) calls as Semantics. Read on. (Please PM me if you need to know more) The old keyword density based method used to write articles is no longer a good idea nor is it sufficient to optimize your web pages. It was based on the premise that Search Engines look at the number of times a keyword or phrase repeats itself on a page so as to deem it relevant to that keyword or phrase and "rank" the page for it. So, why optimizing your pages for a couple of phrases is insufficient? Are the search engines really fed up with the rat race due to the practice they started sometime ago? Okay, the point is keywords are user determined and are mostly synonyms taken from thesauruses or phrases containing the base word. Since search engines have changed their algorithms, you’ve got to be making use of what I call as "Search Engine determined" equivalents all through your articles and web pages if you want to retain your SE rankings. Let me say you want to rank for a particular keyword phrase “abs workoutsâ€; you would be better off using the "semantic" (similar in meaning) words. Well, I will simplify this out for your quick understanding. Since it is not easy to find out the "semantic" words, Google has made our lives easy by letting us search for semantic words of phrases preceded by a tilde (“~â€) operator. You can run a Google search for semantics of abs workouts by typing “~abs workouts†into its search box (without quotes). Lookout for all the bold words in the results page and these are what I mean the semantics. For example, the semantics of abs workouts is here. Semantics for abs workouts (taken from the first 100 results) abs ab abc .... abdominal Workout Workouts Drills ~workouts You may need to conduct the tilde search individually for each word in your keyword phrase. However, the result may surprise you too with irrelevant returns occasionally (try ~apple for yourself). The key is, these are determined by the search engine and not by thesauruses. What the SEs are looking for is "expert phraseology" and terms in relation to your topic all through your page, and certainly not just a page stuffed with a single keyword phrase or built around it with no true relevance to the rest of the content elsewhere on your website. If you optimized your pages or content in the old fashion, that is, around single keyword phrases alone, your pages are very likely to suffer a lot to rank these days. This is because of the algorithm built around the technology called as 'LSI' or 'Latent Semantic Indexing'. Fundamentally, what this new algorithm does is look at your web page and the entire structure of your website from a thematic and relevance point of view. This could mean a lot of work but don’t you think it is worth the effort? (Please PM me if you need help with your article writing)
Great article dude... I have written an article about LSI optimization in my blog... check it out... Advanced SEO: Latent Semantic Indexing (LSI) Unlike yours, I use a different method to get the LSI keywords..
