Research on the key-yahoo of Yahoo optimization

Keyword density in the Yahoo ranking rules still occupy a large proportion, some people feel that if you set the highest possible density in the title tag, you will have a 10% percentage of the overall ranking, and the keywords will be 3% in the ALT, Meta, description, and so on. Header label Export link text and Body keywords will also occupy 3% of the ratio on the surface, Yahoo's algorithm and Google's algorithm are very different, but this is not the case, some of these factors and Google two years ago the algorithm is similar. Since Yahoo acquired the Inktomi, Yahoo has been more focused on the reverse link in the algorithm, but we still believe that Yahoo's algorithm is not derived from Google
When optimizing Yahoo, it should be remembered that Yahoo always values page factors, such as "body, keyword usage and density, bold, header label" instead of non page factors, such as "Import links, link text, and so on." Yahoo likes keywords to appear in the actual site URL or page weight, but here does not show that Yahoo prefers bold and Google's preferred keyword and label density is about 1.5%, and Yahoo's best choice is its twice times 3%, the key to get a good position in Yahoo is about 2.7%-3.3%, other factors like the title tag is probably between 15%-20%. In the new Yahoo algorithm, the title tag is the most important element in the page.
Recently, we've seen a growing proportion of keyword factors in scoring, as this factor is still being abused, but Yahoo is still the only search engine that insists on scoring keyword tags in rankings.
