    Excellent for discovering low competition keywords

    I've enjoyed using Ahrefs to inform content creation due to their keyword explorer being so useful for finding low difficulty keywords. I do prefer the legacy version of their site explorer in comparison to the new format so I hope that they do not retire certain elements of the platform.

But all this comes at a price. Ahrefs is quite expensive, especially considering that even with a subscription, its use is not unlimited.

And believe me, the credits run out faster than you realize.
