Which indexer is good for backlinks?

I researched my competitor, and it seems he is using RankerX like me because the backlinks are quite similar. However, his backlinks have a high index rate while mine have a low index rate.

I don't know which indexer he uses. Can you help me?

Thank you!

If the backlink sources are indeed the same and the method of indexing is the same, the correct answer is the number of index requests.

If you're using a low-quality backlink source and a low-quality indexer, the reason your competitor is indexed better is because they've requested index requests repeatedly.

It's hard to keep track of which indexers your competitors are using, so instead of spending time tracking, find a quality indexer. Many indexers offer free trials.

three tools are best for indexer status of backlinks.

Open Site Explorer

OpenLinkProfiler
