How do I code a backlink checker tool?
- SEO |
Right, so.. any clue on how I'd go about making my own backlink checker tool?
It seems sites like backlinkwatch gather their data from the existing resources of a crawler with a large index (seemingly yahoo, in this case).
Basically, I'm wondering if I can use the Google API (which I have experience with) the Yahoo API (which I don't have a clue in hell about) and whatever else I can find (Microsoft and other folks?) to harvest info on the links to a particular site.
If I can accumulate this data, I can conglomerate it all and weed out duplicate URLs, then render it in a nice table with fields like dofollow, pagePR, domainPR and a few others that I could guess domain authority with.
(PS I am trying to make a free tool)
So, questions:
1) Am I going about this in the right way?
2) Can anyone give me a hint on how to use these API's for my purpose?
3) Are their other sources (crawlers) that I should investigate?
