2. Content relevance. Although external links are related, diversity, universality and other characteristics, but the author found that the relevance is very important in practice, a sales of electronic products Web site links to beauty site, the effect is certainly worse, the content of the relevant degree can be applied to the entire site level, can also apply to the page level, the theme of the site is better, If a site page does not coincide with the entire site theme, but the theme of the page itself and is linked to the page, it will be more than irrelevant page link weight. In fact, the content of the judgment of the relevant degree of what clear boundaries, can only rely on the experience of the construction staff to judge.

Anchor text in search engine rankings have a large proportion. Anchor text is not the more the better, too many may be cheated punishment. Not too much, not too centralized, a website to get the external links all use an anchor text is usually the most important target keyword, often leading to the punishment of one of the reasons, unnatural, excessive optimization obvious. The solution is important pages such as home links as far as possible use the target keyword to do anchor text, the weight of the page can be a variety of anchor text, manually published links can avoid the problem of excessive concentration of anchor text.
4. The location of the link. Site footer, left or right navigation in the advertising section of the Special link page is the most common link and exchange link location, search engine through the page block, you can identify the location of these links to reduce its weight, so the best external links should be in the body, Only the text is the most likely spontaneous link with editorial significance.
5. Click Flow. Click Traffic is the original meaning of the link. But from an seo point of view, external links are the most direct means to improve rankings. If you get a link from a large traffic site, whether or not the link has a nofollow or turn, as long as the click of traffic, can be regarded as a good external links, even if the link can not directly enhance the site rankings.

In terms of external links, not necessarily ranked in the top 10 or the top 20, as long as the top dozens of pages have a certain weight and ranking ability, is a good outside the chain of resources.
7. Page weight ranking. Sometimes the link from the inside page is not necessarily worse than the first page link effect, many of the site inside the page itself has a large number of external links, the weight of the page is also very high, so you can also consider and the site within the link Exchange page.
8. Page Update snapshot. If the snapshot of the page in the search results is very new, description This page is often crawled by search engine spiders, which means that the added links will soon be detected, if the page snapshot date is in the previous months, may be a link after several months to be included.
9. Export the number of links. The more links that are exported on the page, the less weight each link will have, so avoid those pages that are specifically used for Friendship link exchange, which results in poor links.
10. From edu,gov and other domain names. Most of the SEO staff will think that the edu,gov and other domain names of the site itself, the real reason is because in these domain names of the Web site garbage content is less, these sites because of the relationship with other government agencies, scientific research institutions, itself access to high-quality external links than the commercial site is much higher, Even if the weight of the beginning is low, but the link after the cumulative effect will be better.
