Error in Google Webmaster Tools
The error is in the “pages that link to yours” option. It isn’t accurate, it doesn’t show all the sites who really have links to yours. The external links to your site aren’t accurate.
I figure this with this new site who I’m writing. Google Webmaster Tools only shows 3 links to my site but really there are more. I write another web pages with links to my site(they already was indexed by Google), so it should appear like sites with links to yours, but in the option “pages that links to yours” of Google Webmaster Tools it doesn’t appears.
So… here comes the idea, I wrote a tool to find all the web pages that links to my site.
With this tool I found the real total number of web pages in internet with links to my site, and I can see this web pages to verify if it really have links to my site. And for my sites the results are 100% accurate.
Now my online tool shows you how many sites link to your site and the first 10 of this sites.
You can try it here: GooLinks
You should know the difference between this and the Google “link:” operator. This operator returns only the links to a exact URL, not to all the web pages of a site.
For example, you can test this tool with my URL, “goohackle.com”, if you use the “link:” operator in Google doesn’t return nothing, if you try with my tool, returns web pages with links to my site, the correct result expected.
