You can check the backlinks of any site with these tools. I use them for all of the following:
1. Overview of what’s going on with a site (any anomalies etc)
2. Checking for over-optimization
3.Checking competitors to see if they have any good links / trying to jack competitors links
4. Doing general research on domains That all being said, these 3 tools do about the same thing but each one has strengths &weaknesses.
Here’s what I think about all 3:
1. Ahrefs– Best at catching backlinks. Most accurate checker.
2. Open Site Explorer– Most commonly used statistics for judging website power or strength, however DA & PA metrics scale with spam so you really need to look at the actual backlinks too.
3.Majestic- Best for determining websites trust / strength.
