About hits algorithm

The hits algorithm, presented by Cornell University in 1997, is an algorithm for analyzing the importance of a page. The hits algorithm has two concepts, namely hub value and authoritative value.

The value of the hub is the weight and the value of all exported links on the page.

For example: Fuqing SEO Blog Export link 20, these 20 export links of the weight and is the hub value of www.fqseo.org.

Authoritative values mean all the weights and values that are linked to the page that you import.

For example: Fuqing SEO blog site authoritative value is 20, it means that there are 20 links to become Hub value import the page.

This shows that if a page only imports and does not export links, then will lose authority value or hub value, and search engine ranking factor is based on the combination of the two.

About TrustRank algorithm

The TrustRank algorithm was a joint study of Stanford University and Yahoo in the 2004, and the translation came from the Trust index.

This algorithm is relatively easy to understand, and the algorithm represents authority and trust.

For example: There is a high weight of the site link to your site, search engines will feel that your site is also trustworthy. Because search engine feel good site is not bad friend.

A very simple example is that there are 3 sites a-b-c weights from high to low, if your site is imported for a, then relative to your authoritative trust value is high.

So we are now looking for the chain are selected PR high, domain age, authoritative (such as Gov), because this is the public algorithm.

About Hilltop algorithm

The hilltop algorithm is the search engine results sequencing patent that Google engineers obtained in 2001.

The most obvious of the algorithm is the relevance of the link, Fuqing seo can be considered as a supplement to the TrustRank algorithm. Imagine, if there is no hilltop algorithm, then if there are government websites and Fuqing SEO blog to do friends chain, then my SEO blog rankings should be very good, but in fact not seen. Hilltop algorithm takes into account the relevance of the link, once again confirmed that even the high weight but not high relevance of the site link to import rankings is limited.

The hilltop algorithm also has an expert page concept. Search engine for keyword ranking is screened, ranked first is the expert page, if you can get expert page support, then is the highest relevance.
