At the beginning, no one tried to use the method of cheating to build external links, thus affecting the search engine rankings, the network of external links are natural, real. When more and more people realize the importance of external links, they began to use external links to rank cheating technology, such as mass blog comments link, mass forum links. So, to differentiate these cheating external links, the search engine began to study the gap between real good links and junk links, thus forming a set of criteria for judging excellent external links.

1. External links should exist between related pages

Both for search engines and for users, the launch of external link polling pages and the Web pages subject to external links voting should be closely related.

In the past, the construction of external links tended to be more inclined to the transfer of weights. For example, see other people's website PR high, want to through the external link way, let other people's web page to pass higher weight, but ignore the relationship between the content. This content is completely unrelated external links, although there is a certain weight transfer effect, but because the content is not relevant, so the role of the stimulus to the rankings is very small.

From the user's point of view, if a user wants to search for "Mei-pork" by searching engines, come to the Web page that introduces "plum dish pork" from the result of the cable.

This web page introduces a detailed "Plum pork" method, as well as an external link to a "home-cooked recipe", an external link to a football manufacturer's phone. But many visitors will not be interested in the external links of soccer manufacturers.

2. Websites providing external links should be healthy

Connected to the site can be seen as a site group, the site group, each site should be "healthy" and relevant, and should not appear completely unrelated, poor quality, unhealthy sites.

For example, a website is originally to provide high-quality content, natural SEO site, but and a group of low quality, and all because of SEO cheating is severely punished the site for external link exchange, this original normal site will often be considered a low quality, And SEO may also have the site of cheating behavior.

3. The growth of external links to the natural

The growth of external links should be natural, smooth, and should not be an abrupt increase of thousands of external links.

For a website, the user who likes the website will spontaneously recommend to the friend, feel the website valuable other stationmaster will use the Exchange link, the recommendation link and so on the way points to you. This natural external link increase is relatively gentle, there are a certain number of range and law.

If a Web site grows by tens of thousands of or hundreds of thousands of external links overnight, the site is either growing in a way that uses some kind of cheating, or the site itself is being widely watched for important events-a situation in which the mainstream search engine introduces a similar "sandbox" Mechanism: First of all, this drastic change of the site as a cheat site treatment, and put it into the sandbox, with time to verify that this site is really cheating. If it is cheating, then the corresponding punishment, if not cheating, 2-6 months after the release of the sand box, the normal ranking.

For ordinary small and medium-sized websites, if because of external links to increase the exception to enter the sandbox, whether or not cheating, it will take a long time to recover-if not an abrupt increase in external links, this 2-6 months of time, often keyword ranking has achieved a certain effect, the site's brand building is also on the right track, So you don't have to waste time because the external link grows too fast.

4. External link anchor text should be diversified

Anchor text is linked text, in the external links, anchor text should be as diverse as possible, the more natural the better.

In the external links, anchor text to the keyword ranking is very helpful, but search engine optimizer should not all point to their own anchor text set into a unified format, which often may trigger the search engine down the right or punishment.

For example, if the main content of a Web site is about a TV program, then point to the entire site's anchor text link to the home page, may appear the program name, host, program on the television station, the main content of the program, such as a variety of text, rather than a unified program name.

From the user behavior analysis, spontaneous, active reverse link is not possible to use a link text, there will certainly be different perspectives of visitors value different aspects of the content, and then the recommendation of different angles.

5. External links may exist in various locations of the Web page

Excellent external links should not only exist at the bottom of the page, but should exist in all locations of the page.

There are many use hacker technology to invade other people's Web site, and then embed the external link code behavior, in common is that a large number of external links exist in a fixed area of the page, such as the bottom of the page. Such external links are blunt, unnatural, and risky. Normal external links, may exist in the various locations of the Web page, such as the general presence of the site at the bottom of the links, the existence of the content area of the spontaneous recommendation, exist in the text at the bottom of the "reprint source" and so on.

6. External links should come from different IP, different sites, different pages

Because the real external links are often the user to recommend spontaneously, so exist in different IP, different sites, different pages is certain.

If all the external links of a website are from other sites of the same server, the search engine may think that the owner of the site is the same person, these external links are controlled, are not natural, thereby reducing the target site's external link voting role.

7. Appropriate external link exchange

There is no search engine in the network, the external link between the site exchange has already existed, such as links. This normal external link exchange behavior is not considered problematic, and search engine optimizer should be treated with a normal heart.

This is mentioned because some people think that friendship links have become more and more unimportant, and even suggested the abandonment of links. Although the importance of friendship links is indeed increasingly small, but this from the emergence of the Internet, the existence of user behavior, absolutely in line with the nature of the network, it should not be abandoned, the search engine is not likely to be normal links as a cheat.

8. External links should point to various levels of the page

In the site's external link building, do not put all the external links to the home page.

Many search engine optimizer think should first raise the homepage of the main keyword ranking, so all the external links point to the home page. This approach is obviously not in line with user habits, nor is it natural, if too many of the outside chain all point to the home page, may trigger the search engine related punishment mechanism.

The better case is that the external link should point to various levels of the page, such as a site most of the external links are pointing to the home page, but there are one or two of links to the column pages, or even content pages, this is a very normal situation, but also the most natural situation.

Generally speaking, excellent external link standard is only two words: nature. Search engines are designed to serve users, and user behavior is increasingly interfering with keyword rankings. If you want to get better keyword ranking, the natural way to carry out the external link construction is the best, but also the most consistent with the virtuous cycle of the standard way.
