I'm fairly new to SEO. When I put my site through SEOQuake, I took a look through the density report, it brought up something funny. A 2-word keyword phrase is repeated throughout the homepage (and other pages) that is not an intended keyword. One word is an intended keyword, but the other no. The thing is, SEOQuake has determined this to be the primary keyword, because on some pages, it occurs at 30% density! Yikes. So, if SEOQuake has determined this to be a primary keyword, will Google make the same assumption? Also, this keyword is mainly present in a complex-ish, sidebar drop down menu. Thanks!!!
I assume google works the same as above example. Except it will firstly scan for tags,titles and h1. These are the places where the main keyword are placed.Hope this helps.
Google Crawlers always look for content and sitemap, So crawlers can easily find my website and rank on the best position.
