    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. At the beginning of each month, you are allocated a number of credits, which varies depending on the plan, and these credits are depleted as you use many of its features. And believe me, the credits run out faster than you realize.
