External links are an important part of SEO, but many seoer and not to the external links for the research and analysis, just blindly to carry out the external link construction, the following recommended a few I often use the external link query analysis tools, I hope the beginners can help SEO.
1. Yahoo Tools
Http://sitemap.cn.yahoo.com
Yahoo China's external chain query tool, but only show 1000, as if seoer used more than a tool.
2.Smart PageRank

can query the external links of the site and the URL under the link, but the accompanying PR query function seems to be unable to show, more regrettable, than Yahoo tools more refined points.
3.Linkvendor
Http://www.linkvendor.com/seo-tools/domain-popularity.html
Domain name popularity query, you can query the external link domain name, IP address, PR value (PR value function need to register for free), but also to query out of the chain by PR, IP address classification. Query the competitor high quality outside the chain recommend this tool.
4.SEO Tool Software
SEO Elite, Linkdust. SEO Elite 4 Online has free crack version, Linkdust is free software. The former link query function is part of the software, English software, suitable for English. The latter is the domestic seoer developed, including the location of external links and aiming text, and so on, but also a simple classification, can be downloaded online search.
5. Comprehensive query Tools
For example, webmaster home, Chinaz, Admin5 and other types of tools, query the major search engines and the number of the chain, but the macro figures, most of the webmaster use is also more.
6. Common Search engine Instruction
Basically, most of the above tools call Yahoo China or Yahoo's external chain data. However each search engine treats the external link the standard to be different, therefore the search engine instruction to the specific search engine link analysis appears very necessary.
Direct input URL: such as www.admin5.com admin5.com form observation
Domain, link "intext" instruction (Baidu with domain,google link data less)
such as: domain:www.920574.cn
Link:www.920574.cn "
Intext:www.tnseo..com.cn (Google is strongly recommended to use, the average person I do not tell him)
7. Search Engine Webmaster Tools
Basically Google and Yahoo webmaster tools are more popular, but Google Webmaster tools can not check other people's links, personal type, Yahoo belongs to the common type. Baidu does not have webmaster tools, but I never use Baidu statistics. There is the use of Sogou sogou rank and Yodao query tools.
