Findatom (http://www.findatom.com/) is Xwaylab's world's first third-generation Chinese search engine, which employs many new technologies and algorithms to improve the quality of search results.

What exactly defines it as a third-generation search engine? I have consulted a lot of information that should be the definition of the first generation, second-generation and third generation search engines:

First generation search engine: Search engine for content matching based on content relevance.

Second generation search engine: Search engine based on content correlation and Web page weight.

Third-generation search engine: Search engine based on content correlation, Web page weight and user search behavior results.

This shows that the third-generation search engine is "user search behavior."

The so-called user search behavior, refers to the user search the keyword, the gaze stops the webpage and clicks browses the webpage, three are indispensable, therefore the third generation search engine is has the tracking function, in protects the user privacy situation, and unifies the advanced sorting method, may return the user generally likes the search result.

Findatom is such a highly humane search engine. In addition to the very accurate search results, the page's picture preview, text preview is also available, enough to meet the needs of ordinary users.

Webmaster should also grasp the third generation of search engine development trends, to find suitable for the future SEO methods and promotional skills.
