Bear in mind that Yahoo Site Explorer Links API can only provide 100 back link samples at a maximum. They can provide the total number of back links pointing to the domain but this is NOT unique data. You will still need to do some statistical approximation of the overall UNIQUE back link count.

Below is the formula for the unique back link count:

Unique Back link count = (Number of Unique Back links in 100 Yahoo API samples/100) x Total number of back links pointing to the domain (not unique data)

For example, if there are 20,674 back links pointing to the entire domain, and in the sampling analysis of Yahoo Inbound Links API data there are 32 back links from unique domains out of 100 back link samples, the estimated/overall back link count should be:

Unique Back link count = (32/100) x 20,674 = 6,616 unique back links pointing to the entire domain.

Since this is an estimate, this is not guaranteed to be entirely accurate. Use this result only as a rough guide.
