1.http://www.aliyun.com/zixun/aggregation/8475.html "> reverse link with nofollow attribute or chain immediately after delete
Link Exchange is still a white hat method, is to establish a reverse link one of the methods, but unfortunately, there are many illegal webmaster cheat you. When you see someone with your friend chain, the friend chain suddenly disappears or has the nofollow attribute, you should delete it immediately. So you should always check links to see if the link still exists or has nofollow attributes.
2. Reverse link of the site PR high but the anchor text is not appropriate
Site PR High but anchor text is "Click here" or something like this, the validity of this anchor text is very weak. Anchor text keywords are critical, so if the reverse link anchor text is so, this is worthless.
3. Anchor text is the best choice
Sometimes, when the webmaster does not add anchor text but add picture link. Yes, the image link is good, it can even bring you more users than text links (if the image is attractive, of course, the user clicks it), but the SEO perspective does nothing better than the anchor text keyword.
4. If the picture link is the only choice don't forget alt attribute with keyword
Picture links may not be as valuable as text links, but if the image link is the only option, do not reject it. However, make sure that the Alt text link for the image is with the keyword.
5. Get links from a website with irrelevant relationships
Now, this is a very common situation! When exchanging friends ' chains, you should only focus on relevant websites. If you have a dating site that gets an export link from a financial site, it is worthless. Of course, it's not easy to find relevant sites and get links, but unless your site theme is in a very narrow area, there are hundreds of or even thousands of related sites that can get a reverse link.
6. Reverse link Page A large number of export links
It is more valuable to export only one reverse link from a Web page. Many pages have 200 or more links, if your link is one of them this will be the result of this export link is very little. On the other hand, many directory pages, even if there are 200 of links, most of which are nofollow, are still valid even nofollow.
7. Export links on the page the spider cannot crawl
A link may look completely valid (the anchor text does not have the nofollow attribute and the keyword is correct), but it may still be invalid because the page it is on may not be crawled by spiders, or the spider cannot crawl to a dynamic page.
8. Best links
The best way to link the links is not the way to link the picture, but the text to illustrate the link, such as <a href= "http://www.seotea.com" title= "English seo" > website name, Link added title= "Text description" , can better tell the spider, this site is what to do, easy to search the database sorting collation.
9. A separate "link page" is not suitable for a friend chain
There are a lot of sites doing "link pages" like links.htm, Links.asp, links.cgi, and so on. If the search engine sees this, not only can it be recorded as an inner page link, it is more likely to ignore it. So don't exchange links on such pages.
