You may know Google’s link command. It allows you to find web sites that link to another web site which is a special search query .
Give an example, if you want to find web pages that link to Microsoft.com, enter “link:www.microsoft.com” in Google’s search box.
Unfortunately,Google’s link command is not as useful as it used to be. Many links are missing in Google’s link search. Actually,It shows only a small selection of links to yours.
Many people think that Google’s link command only returns links from web pages that have a PageRank of 4 or higher. This opnion is not true.
Google’s search results pages show only a sample of the links that point to a page, so this list is in no way indicative of the link structure utilized by Google to formulate a page’s PageRank.
Google doesn’t show every web page with a PageRank of 4 or higher that links to you,Although many of the returned web pages have a PageRank of 4 and higher.
You can quickly verify that google also often returns pages with a PageRank below 4 by visiting some of the returned pages.
There’s a better way to find who links to your site on Google
Perform a Google search on your URL to obtain a more accurate list of the links that point to your page,
Click the “Find the web pages that contain the term” link on the result page then Google will provide you with the web pages that mention the address.
To remove pages from your own web site from the results, add the term
“-site:yourURL.com” to the query in the search box.
You might also get a few sites that just mention your web site URL without actually having a link. However, the results are still much better than the results of the standard Google link command and it will god for your SEO.
