The number of reverse connections (backlinks) is an important factor used by search engines to determine page rankings. It is important for an SEO to get a correct number of outgoing connections. Not only do we know what's going on in our website, but we can also find out where the gap is with other people by reversing the number of links to other sites.
There are several tools available to check for reverse connections. Here we introduce:
1. Google's link: directive: The search engine provides link: Instructions are the first tools to appear. Microsoft stopped supporting the directive in 2007, while Yahoo put the directive's functionality in the Yahoo! Open Explorer tool (see below). Link is now available: This feature is only Google. Although this tool is the most widely known, but it shows the result is very obvious low.
2. Google Webmaster Tools: In addition to link: instructions, Google in its webmaster tools also provides a reverse connection report. In comparison to link: instructions, Google webmaster Tools to the number of reverse connections is clearly a lot more accurate. The limitation of this tool is that it only shows the number of backlinks that you have on your site, and you don't see any other websites that you don't have. In addition, Google webmaster Tools out of the number although the link: instructions to find out the number of the accurate, but still on the low side.
3. Yahoo! Site Explorer: This tool is the best of all the tools provided by the search engine itself. And so for a long time, the tool was considered the most accurate. Unfortunately, the Yahoo! Site Explorer is no longer updated after Yahoo and Microsoft announced a search for this piece of work. There is more information that the tool may disappear soon.
4. SEOMoz: Because the search engine itself provides tools that are not allowed, it is likely to disappear, so other companies are also starting to develop their own crawler to crawl the entire network, in an attempt to provide you with a reliable number of reverse connections. SEOMoz is a company in Seattle, USA. The two tools provided by Linkscape and Open Site Explorer are based on the crawler that it developed. The tool claims that it has 400多亿个 Web pages in its database. So far, the industry has commented that SEOMoz these tools are still not very stable and that the numbers are too low.
5. Majesticseo:majesticseo is a British company. This is another company that has developed its own crawler to crawl across the Internet. It claims to have 1.8 megabytes (1 trillion is 1 plus 12 0) pages in its database.
Which of the above tools is most accurate? I use the Twitter page of the blogger Rinkello as an example to compare:
1. Google Link: directive: 103
2. Google Webmaster in the report: N/A
3. Yahoo! Site explorer:4,698
4. seomoz:531
5. majesticseo:11,095
As you can see from the above, the Majesticseo provides the most accurate number, followed by Yahoo Site Explorer. SEOMoz and Google Link: The numbers provided by the directive are clearly a quarter from the fact. For the above information, the old cat suggests using Majesticseo to track the number of reverse connections.
