Ask buyers what frustrates them about their SEO tool and the answers come mostly from people who like it: SEO buyers rate their tools well, and many complaints arrive alongside praise. What they complain about is the commercial wrapper and the work around the tool more than its core — add-ons and credits, caps on projects and crawls, platforms that outrun the team, and numbers that are estimates rather than measurements. The tools divide clearly. Price is common on every tool, and on Semrush it is about add-ons and tiers rather than the headline figure; BrightEdge draws complaints that the platform outruns the team; Similarweb draws the accuracy complaint; Ahrefs draws caps and gaps. Most complaining users stay, and nearly half of the completed moves where buyers named a complaint did not lead to another SEO platform the company runs itself.

The six complaints — graded
Each complaint is classified by how buyers in these interviews typically respond: tolerating the issue, working around it, waiting for the vendor, or reconsidering the contract. These are observed responses, not fixed severity ratings; the same limitation may be manageable for one company and unacceptable for another.
Price, add-ons, credits and tiers
Common on every tool, and on Semrush it is about the commercial wrapper rather than the headline price. “It's very difficult getting into SEMrush to know the price you're actually going to pay to get enough credits to do what you want to do,” says one user; another describes “add-on after add-on after add-on to try and design the environment that you need,” and a third found it “really frustrating that they kept moving the goal line.” An Ahrefs user finds it “can be very pricey, especially as new features get added, like API usage,” and a Similarweb user calls it “kind of pricey for what it is.” Price appears in more than half of the completed moves where buyers named a complaint as the reason, more than any other.

Caps and gaps
Limits on tracked projects, keywords, competitors and crawls, and jobs the tool does not do. It is Ahrefs' signature: “some of the functionality that I expected to have maybe isn't there or is on a higher tiered plan, such as keyword tracking.” A Semrush user who arrived from an enterprise platform doubts it “can handle very, very large organizations,” and a Similarweb user notes it “only covers desktop web and mobile web, leaving us with a huge blind spot.” Buyers mostly work around it with a second tool — one team describes a gap “which is why we were looking for a secondary tool” — and the moves it does drive are scale moves, to a bigger or broader platform. For why many teams run several tools, see the second lesson on what SEO buyers wish they'd known.

Too much tool for the team
Platforms that are dense and hard to learn, or that sit under-used without an SEO operator. It is BrightEdge's signature: nearly seven in ten of its complaining users raise it. “It's very hard to find a person, the end user who operates on the platform that squeezes the platform and maximizes its utilization all the way to the end,” says one BrightEdge user, and another allows that “it may be user error, but again, the platform just isn't super intuitive.” Self-serve suites draw a milder version: “There's just so many different facets of Semrush that I feel a bit overwhelmed,” and one Semrush user calls it “a super steep learning curve, which is why I'm always looking for somebody who has some sort of SEO background.” Most buyers live with it or hire for it; on enterprise platforms it can end the contract when nobody is left to run the tool. For why a platform does not replace an SEO person, see the fourth lesson.

Numbers to take with care
Buyers raise concerns about modelled traffic estimates, fluctuating rankings and delayed or incomplete reporting. Similarweb draws the clearest complaints about estimates that differ from internal analytics, though the two do not measure the same thing — third-party traffic models, recorded site visits and Google's search data use different methods, so a discrepancy does not by itself establish an error: “sometimes their data can be directionally correct, but it's not as precise as our internal data because it is based on estimates,” says one user, and another finds “the algorithms they use behind the scenes are not that clear” when the figures have to be reconciled with the business's own. Google Search Console draws the same complaint from the other side — “some data can feel sampled or delayed” — and a seoClarity user finds that “The rank data is very volatile.” Semrush users raise it less, and mostly about traffic estimates rather than keyword data. Buyers treat modelled figures as directional, watch ranking changes over time and compare relevant metrics with their own analytics and search reporting: “We typically track ourselves within the platform so that we can tell how accurate or not we think the data is.” Those comparisons help spot unexpected differences, though they cannot always validate one figure against another. Few buyers leave over it alone.

Slow to change, behind on AI search
A complaint about the self-serve suites more than the enterprise platforms. “I don't feel like that tool in particular has evolved that much over the years,” says one Semrush user, who keeps it anyway because it is inexpensive; another says “I don't think that they develop things as quickly as we would want them for being such a big tool in the market,” and an Ahrefs user notes “I feel like I've seen less new features in Ahrefs.” One Semrush buyer calls it “more of a legacy product that is trying to improve itself.” It leads the evaluations here, but most of those buyers are looking to add an AI-visibility tool beside the suite rather than replace it — see what AI-visibility buyers wish they'd known. It is rarely the only reason anyone leaves.

Support and account service
The least frequently cited of the six, but the buyers who raise it are relatively likely to describe replacement activity — a completed move, a plan or an evaluation. The number of cases is small, and support almost always appears alongside another concern, such as price or a missing capability. It splits the enterprise platforms from the self-serve suites. A BrightEdge user describes the cost of a rebuilt account team — “It takes them at least a few months to understand what we're doing” — and another finds the platform “a little bit more self-service than I would personally want.” A Semrush user wishes “they had more training that they could provide or more of a day-to-day account manager,” and another that “Their customer service isn't great sometimes, but that's about it.”

Two further complaints sit outside the matrix. Audits that over-flag or recommend without doing are mostly a Semrush complaint, and they are covered by the third lesson on what SEO buyers wish they'd known. And getting data out is a complaint about older tools: “to get data out of them is like pulling a tooth,” says one buyer, and another has “to go month by month and pull the data manually.”
Who leaves, and why? Most complaining users stay. Among completed moves where buyers named a complaint as the reason, price appears in more than half, and caps and gaps in about half — usually moves to a bigger or broader tool. A single move can involve both, so the shares overlap. The destinations are the surprise: nearly half of those moves did not lead to another SEO platform operated by the buyer. Some companies dropped the subscription or the work, others transferred SEO to an agency, and some turned to an AI assistant. Those outcomes differ — an agency may still run paid SEO tools, and an AI assistant is a different workflow rather than no software at all. The rest went to another self-serve suite or to an enterprise platform. Slow progress on AI search leads the evaluations, mostly as additions. For where Semrush leavers go, see Semrush alternatives.

The counter-current: complaints from mostly satisfied users
Many of these complaints come with praise attached. A Semrush user notes “They've been pretty consistent with their pricing strategy as well. It's not like they're changing prices every year,” and another says that once “you get enough tokens to deal with your quantity of data, it works pretty well.” A Similarweb user puts the trade plainly: “It's a very complex tool. We need to have good training on it, but really the license is worth it.” An Ahrefs user says “The way that we use the tool, it does its job well,” and a Conductor user watched the vendor fix the complaint: “I think they've really leveled up in the past year or so and strengthen their team and gotten far more innovative.” Before you conclude the tool is the problem, separate the commercial terms from the product, and the product from the team running it.
What this means — whether you run one or you're buying one
If you already run an SEO tool, most complaints are worked around or tolerated: buyers add a second tool for the job the first one caps, read estimates directionally and calibrate them against their own data, and hire or train for the platform's depth. Price is different: it is the complaint cited most often in completed moves where buyers named a reason. Support is raised less often but is more often tied to replacement activity among the buyers who mention it, usually alongside another issue rather than on its own. If you're evaluating one, our recommendations — not practices buyers describe — are to price the plan you will actually need, including the add-ons, credits and tier for the projects and keywords you track; to check the caps against your site's size; to have the person who will run the tool use it during the trial; and to compare a tool's figures for your own site with your analytics.

Common questions
What are the most common complaints about SEO tools?
Among the Semrush, BrightEdge, Similarweb, Ahrefs and other users in these interviews, six complaints recur: price, add-ons, credits and tiers; caps on projects, keywords and crawls, and jobs the tool does not do; tools that outrun the team running them; numbers that are estimates rather than measurements; slow product change, especially on AI search; and support and account service. Many of these complaints come from buyers who are otherwise satisfied. Among completed moves where buyers named a complaint as the reason, price appears in more than half.
What are the biggest complaints about Semrush?
Semrush users in these interviews most often raise price — in particular add-ons, credits and features gated behind higher tiers rather than the headline price — along with caps on projects and keywords, and slow progress on AI search. Few raise its keyword data as inaccurate; the accuracy complaints that do come up are mostly about traffic estimates. Support comes up less often than for the enterprise platforms.
What are the biggest complaints about BrightEdge?
BrightEdge users in these interviews most often say the platform outruns the team running it — powerful, but hard to use fully without an experienced SEO operator — followed by support and account service, and price. Buyers who have the vendor's team or managed service behind them are the most positive.
What are the biggest complaints about Ahrefs?
Ahrefs users in these interviews most often raise caps and gaps: features such as keyword tracking on a higher tier, limits on site audits and API usage, and a narrower toolset than Semrush at a similar cost. Some also raise price and slower feature development.
Why do companies switch SEO tools?
In these interviews, price appears in more than half of the completed moves where buyers named a complaint as the reason, and caps and gaps in about half — usually moves to a bigger or broader tool. Nearly half of those moves did not lead to another SEO platform the company runs itself: some dropped the subscription, some handed the work to an agency (which may still use paid tools), and some turned to an AI assistant. Slow progress on AI search leads evaluations, though most of those buyers are adding an AI-visibility tool rather than replacing their SEO suite. Most complaining users stay.
