12 website experience to summarize the six stages of SEO outside the chain

As early as 1998 began to do Web pages, these more than 12 years, witnessed the changes of the entire Internet. Today to briefly summarize the site to do these years, the site link change process. For your seoer to check their work in the outside chain position.

First Stage

The earliest links, is the pure link, at that time the engine has not been based on the link algorithm, so the site links to other sites, is simply to enable visitors to benefit. Gradually, the engine began to pass this, to distinguish which sites are of high quality, giving high quality priority rankings.

The seoer are also beginning to realize the engine changes, so, seoer to do their best to make every site to establish links to their own site, regardless of the good and bad links, regardless of the origin and origin of these links, anyway is a lot of unrelated sites, linked together.

Second Stage

In seoer efforts, the site rankings have changed, in the short term, many poor quality of the site, have been very good rankings. The engine then adjusts the algorithm.

Search engines found that the link from the important site than from the unknown site of the quality of the link is significantly higher, so, the link to add a number of criteria for evaluation, which is important standards of quality and quantity. This algorithm changes the number of sites that contain links to low quality sites with little rankings.

Seoer found the change and made technical adjustments: "Get links from the most important websites." So, seoer to find the most important web site, so that their own site to join such sites, such as the Yahoo directory, as well as countless other small directories, are seoer must go to. Seoer's efforts to make those just fell into the bottom of the site, and then climbed to high.

Phase III

Search engines found that many directory sites did not care what links they had exported, and popular important sites seem willing to link to any site, regardless of whether the links are related, so the engine into the algorithm adjustment, the engine that the current import links are linked to the homepage of the site, and the site is rarely linked to the page, so, Start focusing on the anchor text for each hyperlink and the links to the site's pages.

When Seoer found that the high ranking of the site gradually retreated to the second line, this just understand that the engine to do only the homepage linked to the site down right. Seoer began a "deep link" technical adjustment, which focused on making the other site contain links to internal pages of its own site, creating a large number of such two-way links between them.

Phase IV

Seoer's efforts to make the search engine aware that two-way links do not have a one-way link quality is high, so the search engine to adjust the algorithm, reduce this reciprocal nature of the site rankings, and improve those with many one-way links to the rankings of the site.

Fortunately Seoer can also find this situation in time, so, Seoer began in other sites BBS, blogs, guest books and other places to accumulate their website Web site. Gradually, the SEO software development into the spring, and for the seoer hand-piling site work.

Fifth phase

The mass SEO software makes the search engine for each type of link to do more detailed inspection, and reduce those have dozens of or hundreds of export links of the importance of the page, but the algorithm did not make major changes, still very focused one-way links.

Seoer found that the effect of software mass is getting worse, and then find another way: "In high-quality sites to buy one-way link", because the search engine can not distinguish a one-way link is free or charge to provide, so seoer everywhere to buy a large number of high-quality links, again so many unknown new sites, Has a high ranking.

Sixth phase

The search engine found some sites that didn't make any improvements, but got a lot of quality links, and their rankings soared, finally, the engine was tuned, and the engine began to focus on the absolute relevance between links, reducing the importance of high quality without relevance links.

Seoer also smell to this point, so the technical adjustment, "buy high-quality related industry site one-way link", and, these links directly linked to a very deep site inside page.

The above is I do the site, encountered outside the chain changes, the article may be omitted, please the reader criticized.
