Since Xianyang SEO added to the city after the alliance, found that everyone in the group are crazy to exchange links, for a new station, exchange links is a very good increase in the chain and get the weight of the site method. But there are two sides to everything, if there is no choice to add friends chain, or endless add, to the site can only be harmful without a benefit.

Add friendship links must be cautious, do eye view, ears (a bit exaggerated, hehe). Since said so glare, that add friend chain should pay attention to Which? listen to Xianyang seo one by one for you to:

1, check the other site IP. The site of the same IP is best not link, otherwise spider will think cheat. How to check? Use the website IP address query tool. If you already have a lot of links, want to know if they have and you stand in an IP, you can use the Link IP Bulk query tool.

2, check the other site is punished. If you are being punished by search engines, do not chain. about how to view the site by K, or search engine into the sandbox, Xianyang SEO in the previous article has said.

3, see the other side of the link is the use of JS call output. The search engine to JS is not crawl, if this is the case, do not chain, to your station has no meaning. To determine the use of JS to call the link method: Put the mouse on the link, see the browser bottom left corner of the status bar, if the display is not your URL, but a long list, that is called.

4, see whether the links use the nofollow tag, this tag is to limit the spiders to the URL, such links are also no use. View the method: Look at the source of the other site, first look at the link to the place, there is no use of rel=nofollow, and the head of the site has no use nofollow tag.

Xianyang seo in [Xianyang seo: Interpretation of Baidu "Search Engine Optimization Guide v1.0"] mentioned, Baidu on the IFRAME tag is not crawled, so the friend chain exchange is also useless. View method: Look at the source code, Friendship link area is not an IFRAME tag.

7, check the other side of the form of friendship links. It is best to use text links, if the other side use the picture link, tell the other side in the picture link Alt tag, that is, the mouse on the picture, there are text prompts.

8. Check the location of each other's links. If it is placed in a special link to the page, do not exchange. Search engines are unfriendly to such pages.
