The best service right now is linkchecker.pro
Shows Overall Project Statistics
You can choose a category, and it automatically detects where the link is placed – from an image, for example
Indexing status is visible, along with a check for dofollow/nofollow.
Overall, it’s currently the top service for link checking. There is also a self-hosted enterprise version for $1,000.
Why monitor links at all? Most paid links die within a year – only 50% of what was bought remains. Therefore, it’s an absolute must for link building.
