Author: NO.1 SEOSince October 21, and many owners observed in Yahoo! Site Explorer backlinks in query dramatic reduction site to reduce the rate to half or more. I was responsible for a number of sites can be clearly observed in this phenomenon. Before the larger station more than 5,000 backlinks, now only 2,000 less than the amount collected is also down nearly 4 percent, the site included a smaller reduction was not obvious, the reverse link are reduced by about half.

However Yahoo! Site Explorer results does not mean that the reduction does reduce the number of backlinks, because no one data source is entirely accurate, and my site traffic and ranking them were not affected, which means most likely data itself.

For this, Yahoo! Site Explorer product manager Hemant Minocha conducted high-profile response (link here: yahoo):

We are working with Microsoft team has been to ensure that owners are still able to use Yahoo! Site Explorer to see the site back links, and data will be provided after the CSV export function.

Bing Yahoo! search has been replaced by the two engines of the data to be integrated is sooner or later, is not caused by integration? We can safely guess the following possibilities:

1) Yahoo! Site Explorer Google has also begun to learn to hide the real data (using the Google search command link: domain.com reverse link data found that only 1% of the actual data)

2) Yahoo! Site Explorer backlinks and included changes in the amount of statistical algorithms (with Bing integration), so drastic changes in the data

Conclusion: As long as traffic and ranking are not affected, these results only clouds.
