The risk aversion and Links blog

link address

Links is mutual promotion between blog sites in a way that is usually composed of blogs and personal web sites only, can be personalized, the portal is usually not Links. If the blog program content did not change it is possible cause is noble baby downgrade home page link, obviously, links to some cheating or spam sites will be noble baby downgrade, in addition, there are several possible link exchange risk, we need to pay special attention to.

The number of

Links number should not be too much, the number of control in less than 50, too many links to search engines will not be indexed, but also have a negative impact on the site, if more than 50 links, you should add the nofollow attribute or Javascript form, otherwise easy to search engines that are linked factories for demotion or punishment.

The correlation between

should be added to the same type of blog link, blog content should be relevant, if the content does not have the relevance, the search engine will often be considered cheating.
