OP, thank you for 20 credits to try your indexing service.
I didn't expect to index practically anything (because of the links I used) but OP's service indexed 50% of the links which is quite surprising and good. And it's only $0.02 per link which is cheap, especially at a time when people are struggling to index anything.
Yesterday, I added 3 more new links and they were all indexed so the total indexing rate for me was about 60%.
Also, OP told me that it was possible to have the package lasting 6 months so for $10 you get 500 links to index within 6 months. Which is a good plan for people who don't need to index thousands of links.
