Like all backlink monitors, it doesn't pick up anywhere near all backlinks and is slow to pick up new backlinks. However, all backlink tools have this same problem and Ahrefs is the best of those tools. One of my biggest gripes is that Ahrefs drops backlinks and count them as a lost domain, but after looking into the dropped campaigns you find that a majority of them are still there and Ahrefs dropped them from your backlink profile for an unknown reason.
One thing I don't like is that Ahrefs sometimes does not provide exact keyword search volume. Instead – it provides approximate numbers which confuses us in cases when we think a keyword should get more traffic that it actually does once the SEO content is published. To get the most up to date and exact numbers, you'd better off use Google's keyword planner.
The Content Explorer is a nice addition for convenience, but it doesn't come close to replicating what a tool like BuzzSumo can do. Then again, it likely isn't intended to, but it's the one area of the product that feels like it might be a bit tacked on at this point. This isn't so bad though as the feature still offers a useful purpose, it's just that purpose is a little shallow.
Many websites rely on other traffic generation methods such as traffic from social media, email, referrals, and direct traffic sources over search engines. For sites like these, SEO errors aren’t as important because search engines aren’t their #1 traffic source. For a smaller website, a couple of errors can have a much bigger negative effect than those same errors on a larger website.
Checking a website’s on-page health is indispensable to making and keeping a website SEO- and user-friendly. Whether you manage a small website or a large one composed of thousands of webpages, detection of issues can be challenging. You just cannot afford to spend days looking for every possible mistake in the code or checking for broken images or URLs.
Ahrefs make use of two link updates in your website - the Fresh Index and the Live Index. Fresh Index which updates at a longer time frame. It shows the dead links on your website, giving you the chance to change or reclaim the dead link. The Live Index, on the other hand, makes link updates every 15-30 minutes. This provides you with the chance to see regular link updates on your website.
