I have not really had much luck with this one. Meta tags are recognized. Not case sensitive. This is one of the better ones. And they get new listings on board in a reasonable time.
Indexing is less than a day.
Case sensitive . The good old standby . But it takes about 6 months to be listed in there if you are lucky. Meta tags are recognized. This is supposed to be good, but I find that they do not respond to a lot of different keywords, and it is almost impossible to be listed within a reasonable time frame. .
