OK, I admit a bit harsh headline - but it's true. Besides the resent changes in google favoring the social graph - content is still relevant for your sites and backlink strategies - surprise ;-) This is about how the search engines look at your content so you can create/spin better content. I have been working on generating premium unique articles/content, based on keywords, for years on and off. A resent JV kicked it back to life at full speed again. Well you will hear more once it's ready and all that. While working on this I went through my private files and notes about this. Some of the notes are based on datasets published by the search-giants for other purposes. I realised this info is still not available anywhere so because I'm a nice guy and all I want to share parts of this in public. Search-engines index their content via it's crawlers and store them in several tables in their advanced database-setup. When searching for content (or detecting dublicate content) search-engines split combinations of words together also refered as n-grams. There are stored several million ngrams. "this is cool" is a 3 word ngram "this is awesome" is also a 3 word ngram that has the same meaning. Since the search-engines don't really understand the content - it uses a lot of ngrams to link (or glue) searches/relevance together. How many tires of n-grams that are stored are hard to say. I have proof that Microsoft stores up to 7-tiers n-grams. So nearly every combination of 7 words - a LOT of data I can tell you. You can think of this as a MONSTER spyntax-database on steorids. ngrams is just a small part of the game creating a search-engine. Let's look at some real examples from a real database (simplified for better reading): Code: as growth is unlikely to | is set for zero growth as growth is unlikely | economic growth as growth is unlikely | growth as growth is unlikely | is forecasting gdp growth Another example: Code: bruce almighty | also generated the | bruce almighty earned bruce almighty | also generated the | bruce almighty bruce almighty | also generated the | film bruce almighty bruce almighty | also generated the | jim carrey comedy bruce almighty So you see here that bruce almighty is also linked to "Jim Carrey" and knows that it's a comedy. Code: cisco systems plans to announce %%number%% | cisco systems is to announce %%number%% clinton said %%day%% . | clinton said on %%day%% Note here that days and numbers can vary in a single ngram. Please spare us all for comments like - you knew that and have done it for years. Enjoy and hopefully I have helped you a bit.
