Opensite explorer results and old links

[ThomasH]

Hello,

Within a week after the penguin update (Apr. 24), I removed all site wide footer links pointing to my site. However, if I run a opensite explorer on this site I still see these links pointing to my site. And I'm sure I deleted them!

How long will it take that these links disappear from  the opensite explorer results?

Do you think Google's algorithm has the same results to check my website on? Or does the algorithm have another "tool"?

Thank you.

Regards,

Thomas

@ Ryan, thank you for your detailed answer!

If you visit http://www.opensiteexplorer.org/ there is a link which says "View update calendar". If you view that link you will notice the OSE data was updated on May 31st and the next update is scheduled for June 27th.

If you are seeing links which you are sure have been removed, it is likely the links were removed during the crawl cycle which was published on May 31st. It takes roughly a month for SEOmoz to crawl the web, process the data then publish it. In summary, the data is 30-60 days behind.

As sophisticated as the SEOmoz crawler is, Google's is a lot better. Google's crawler is the best in the world and obtains more data, faster, then anyone else. Even so, when you remove a footer link, it usually applies to every page on the site and it generally takes Google several weeks to crawl every page of a decent site.

The last Penguin update was around May 25. I would expect the next update around June 26th. To be clear, I have absolutely no insider information on this topic. It is a complete guess based on the prior updates being released a month apart (April 24th & May 25th respectively).
