In 2026 there are more than 450 SEO tools on the market, and around a hundred arrived in the last year: almost all of them to measure visibility inside AI-generated answers. The count comes from Morningscore, which says it has tested more than 180. That number explains why the right question is not which tool is best, but how many you need.
SEO tools are software that collect data on searches, rankings and the technical health of a site, and present it in a readable form. They don't make decisions and they don't write strategies: they measure. Between them they cover four different jobs, and most sites need two.
Below you will find prices checked on the vendors' official pages on 24 September 2026, UK search volumes for every tool (our own data, I haven't found it published anywhere else) and three stacks with their annual cost. If you are looking for keyword research specifically, we have a dedicated piece on keyword research tools; this one is about the whole set.
The four jobs an SEO tool can do
Fifty-item lists mix up categories that don't replace one another. A crawler and a keyword database don't compete: they do different things and you need both. There are four jobs.
- Search data. Volumes, difficulty, who ranks for what. This is the job of Semrush, Ahrefs, Sistrix, SE Ranking, Ubersuggest and, for Italy, SEOZoom.
- Technical diagnosis. Crawling the site, indexing errors, speed. Screaming Frog, Sitebulb, PageSpeed Insights, and partly the suites.
- First-party data. What really happens on your site: Search Console, Analytics, Looker Studio. Free, and no paid tool replaces them.
- Visibility in AI answers. The category born in 2024 that became crowded in 2026: tracking whether and how a brand is cited by ChatGPT, Perplexity, Gemini and AI Overviews.
A thirty-page site that hasn't yet aligned its content with search intent doesn't have a tools problem: it has a content problem. Paying $200 a month to measure more precisely a site that has nothing to measure is the most common spend and the most pointless.
Which tools people in the UK actually search for
Most articles on SEO tools copy the same order of importance, and it doesn't hold in every country. You can see it in search volumes. We pulled Google's average monthly searches in the UK for the name of each tool, updated to September 2026.
| Tool | Monthly searches in the UK | Average CPC |
|---|---|---|
| Google Search Console | 135,000 | £5.89 |
| Google Trends | 90,500 | £4.94 |
| Semrush | 27,100 | £2.08 |
| Ahrefs | 18,100 | £9.34 |
| Answer The Public | 8,100 | £7.67 |
| Ubersuggest | 6,600 | £9.27 |
| Screaming Frog | 5,400 | £3.05 |
| SE Ranking | 4,400 | £1.04 |
| Keyword Planner | 4,400 | £8.02 |
| Moz | 2,900 | £7.67 |
| Surfer SEO | 1,600 | £2.74 |
| Rank Math | 1,300 | £0.69 |
| Yoast SEO | 880 | £1.10 |
| Seobility | 720 | £2.33 |
| Sistrix | 590 | £2.33 |
| Mangools | 590 | £1.57 |
| Majestic SEO | 390 | £0.86 |
| SEOZoom | 30 | n/a |
Three things this table shows that you won't find in the usual lists.
Tools don't travel between countries. SEOZoom is the second most searched paid suite in Italy, where it gets 8,100 searches a month, more than twice Ahrefs. In the UK it gets 30, because it is built on the Italian database. In the UK the leaders are Semrush (27,100) and Ahrefs (18,100). If you copy a list written for another market, you end up recommending the tool your competitors don't use.
Sistrix is marginal: 590 searches a month, fewer than Yoast. In Germany it is the market standard. It is the clearest case, along with SEOZoom, of a tool that doesn't transfer from one country to another.
The most searched tools are free. Search Console and Google Trends together get 225,500 searches a month, more than three times all the paid suites in the table added together. Which leads to the next question.
Free tools: how far they go and where they stop
Search Console is first-party data, so it is the most reliable you will ever have: these are the impressions and clicks Google actually recorded, not an estimate. The limit isn't quality, it is volume. The web interface shows up to a thousand rows per dimension, and even through the API the documented ceiling is 25,000 rows per call, with a default of a thousand (Search Analytics API documentation). On a site with tens of thousands of queries, whatever doesn't fit in those rows you don't see.
The free version of Screaming Frog crawls 500 URLs and keeps all the analysis features: broken links, metadata, hreflang, duplicates, structured data validation, integration with Analytics and Search Console (official pricing page). The $279 annual licence only removes the URL limit. For a 40-page brochure site the free version is more than enough; for an ecommerce site it is no use at all.
Google Ads Keyword Planner gives real search volumes, the same ones behind the table above, but it shows them in wide ranges if you have no active campaigns, and it groups different keywords under the same volume. Google Trends gives the ratio between two terms over time, never the absolute value.
With free tools alone you can run a complete technical audit of a small site and understand what is already working. What you can't do is look at competitors: no free tool tells you which keywords someone else's site ranks for, and that is the reason people pay.
Paid suites and what they cost today
The prices below come from the official pages, checked on 24 September 2026. I have kept each vendor's own currency: most quote in dollars, Sistrix in euros, and converting adds an error while the price lists keep changing.
| Tool | Entry plan | Price with annual billing | Entry plan limits |
|---|---|---|---|
| Semrush | SEO | $117.33 a month | 5 sites, 500 keywords a day |
| Ahrefs | Lite | $129 a month (monthly price list) | 5 projects, 750 keywords, 100,000 crawl credits |
| SE Ranking | Core | $103.20 a month | 10 projects, 2,000 keywords a day, 100 prompts |
| Sistrix | Start | €119 a month (monthly price list) | 1 user, 3 projects, 3 months of history |
| Surfer | Discovery | $49 a month | 120 documents, 10 tracked pages |
| Screaming Frog | annual licence | $279 a year | no URL limit |
Ahrefs also has a Starter plan at $29 a month, with very limited features, and an Enterprise plan at $1,499 a month with an annual commitment. Semrush goes up to $248.17 a month with the Pro+ plan (15 sites, 1,500 keywords) and to $455.67 with Advanced, which is the first to include share of voice. For an agency with around ten clients, Pro+ is the plan where the site limit stops being the constraint.
A note on the comparisons doing the rounds: list prices can't be compared line by line, because the limits take different forms. Semrush counts sites, Ahrefs projects and crawl credits, SE Ranking projects and daily keywords, Sistrix users and months of history. A $129 plan and a €119 plan can be worth three times or a third of each other depending on what you need to do. For a feature-by-feature comparison we have a separate piece on SEO software and their price lists.
National tool or global tool
The difference that matters is the depth of the database on the queries of your market, and none of the vendors publishes it in a verifiable form. What can be said for certain is the rest.
Some markets have a national tool built on their own database: SEOZoom in Italy, Sistrix in Germany. For a UK site that doesn't apply, and the choice is between the global suites. Semrush, Ahrefs and SE Ranking quote in dollars and Sistrix in euros, so for a UK business the invoice comes from abroad, in a foreign currency, and a VAT-registered business accounts for the VAT itself under the reverse charge. On one subscription it is a small admin difference; on ten it becomes work for your accountant.
If the site also sells in Italy or Germany, the national tool for that market is worth a look, because it is a different database. That is why on multi-country projects we almost always end up with two subscriptions, one national and one global, and it isn't a waste.
A check you can do in ten minutes before paying: take five keywords from your sector that you know for certain bring enquiries, ask each tool on trial how many monthly searches they get, and compare with what you see in Search Console. The tool that comes closest to your real data is the one with the best database for your slice of the market. That test is worth more than any review.
Tracking AI answers: the category that is changing price lists
Of the roughly one hundred new tools Morningscore counted in 2026, most are there to measure visibility inside generative engines. The suites have responded by putting prompt tracking in their higher plans, not in the entry ones.
- Semrush: the $117.33 SEO plan doesn't track prompts. The first plan that does is Starter, $165.17 a month on annual billing, with 50 prompts a day. The step up costs about $574 a year.
- SE Ranking: the Core plan includes 100 prompts; the AI Search add-on costs $71.20 a month on annual billing, about $854 a year extra.
- Surfer: sells tracking as a separate product, AI Search Analytics at $82 a month for 50 prompts a day.
- Ahrefs: Brand Radar AI starts at $199 a month, on top of the Lite plan.
Is it worth the money in the UK? It depends on how many of your customers already use AI to find information, and there is UK data on businesses: according to the Office for National Statistics (Business Insights and Conditions Survey), around 35% of UK businesses with 10 or more employees reported using at least one AI technology in June 2026, up from around 12% in September 2023. It has nearly tripled, and it is still a minority.
As a decision: if you sell to businesses, in 2026 prompt tracking is useful for seeing where the market is heading, not for justifying a budget. If you sell to a consumer or tech audience it is a different story. We set out the method for measuring it in the guide to AI visibility tools, and the strategic context in the piece on generative engine optimisation.
A note on evaluation criteria: Zapier has added visibility in AI answers to the five criteria it uses to judge an SEO tool, alongside features, value for money, usability and integrations. For most B2B sites the fifth criterion still weighs less than the other four. But it is the direction of travel.
Three stacks and what they cost per year
| Situation | What goes in | Annual list price |
|---|---|---|
| Small site, no budget | Search Console, Analytics 4, Google Trends, Keyword Planner, free Screaming Frog (500 URLs), free Rank Math or Yoast | 0 |
| One site, ongoing work | Semrush SEO plan, annual + Screaming Frog licence | $1,687 |
| Agency, ten or more clients | Semrush Pro+ plan, annual + Screaming Frog licence | $3,257 |
| Adding AI answer tracking | Semrush Starter instead of the SEO plan, or SE Ranking's AI Search add-on | +$574 or +$854 a year |
The step from the first level to the second is worth the money when you start asking what competitors are doing, not when you want to measure yourself more precisely. The step from the second to the third is worth it when you have more than five clients, because that is the point where the time spent exporting and stitching data together costs more than the subscription.
One line is missing from this table, and it isn't a subscription: the hours needed to learn what you buy. On Semrush or Ahrefs a professional takes weeks to cover 80% of the features. Screaming Frog can be learnt in an afternoon, but reading a 40,000-URL crawl takes experience, not a tutorial. That is why a small stack used well almost always beats a big stack used at 20%.
What you won't find in any tool
At Macropix, a Milan-based maker of custom LED screens, the heaviest keyword was "ledwall": 4,400 searches a month in Italy, with the site outside the top ninety results. Today it is in second position, with a share of voice of 25.55% across the basket of tracked keywords, ahead of Amazon. The full story is in the case study on SEO for manufacturing.
No tool had suggested that keyword as a priority. The tools had it on the list, along with two hundred others. The decision was understanding that an industrial buyer types the product or process, not the supplier's name, and that came from talking to buyers, not from a report. You measure ranking factors with tools; which content to build you decide by looking at who buys.
The other two things a tool doesn't do: it doesn't tell you whether your backlink profile is credible or inflated (authority metrics are proprietary estimates by whoever sells the tool, not Google numbers), and it doesn't distinguish a ranking that brings enquiries from one that brings visits. On that second point we wrote about which SEO KPIs to watch so you don't confuse the two.
If you are weighing up buying a tool or handing the work to someone, the maths is simple: $3,257 a year of licences buys the data, not the work, and licences on their own produce nothing. You can compare that with the cost of a managed SEO project, and the results we have achieved are in our projects.
How to choose in a week
- Connect Search Console and Analytics 4 and look at three months of data. If you don't have them, any paid tool is premature.
- Crawl the site with the free version of Screaming Frog. Under 500 URLs you get a full technical audit without spending anything.
- Pick five keywords you know bring enquiries and put them into the free trials of two tools. Compare the volumes with Search Console.
- Look at the number of sites and keywords the entry plan includes, not the list of features. That is the limit that will force you onto the plan above.
- Pay annually only after two months of real use. A 17-20% discount doesn't make up for a subscription you never open.
For the technical side and for keyword research we have two guides that go into detail on what to do with the data once you have it. And if your starting point is a checklist, there is the SEO checklist.
SEO tools FAQs
It depends on the job. For first-party data, Search Console and Analytics 4 are free and irreplaceable. For technical diagnosis, Screaming Frog. For search data in the UK, Semrush or Ahrefs; for Italy, SEOZoom. No single tool covers all four jobs well.
For a site under 500 pages they are enough for a technical audit and to understand what already works: Search Console, Analytics 4, the free version of Screaming Frog and Google Trends cover all of that. What no free tool does is show you which keywords your competitors rank for, and that is the main reason people pay.
Entry plans for the suites range from $49 to $129 a month: Semrush SEO plan $117.33 and SE Ranking Core $103.20 with annual billing, Ahrefs Lite $129, Sistrix Start 119 euros a month. A Screaming Frog licence costs $279 a year. A complete stack for one site stays under $1,700 a year; for an agency with ten clients it comes to around $3,300. Prices checked on the official pages on 24 September 2026.
Both cover the UK and international markets. In the UK Semrush is searched 27,100 times a month against 18,100 for Ahrefs, so it is the more common choice among your competitors. The entry plans cost $117.33 and $129 a month, but the limits differ: Semrush counts sites, Ahrefs projects and crawl credits. The deciding test is to compare the volumes each gives for five of your keywords with your Search Console data.
In 2026, if you sell to businesses, it helps you see where the market is heading more than it justifies a budget: according to the ONS, around 35% of UK businesses with 10 or more employees use at least one AI technology, nearly three times the 2023 figure but still a minority. Tracking costs between $574 and $854 a year more than the base plan of the same suite. For a consumer or tech audience the assessment changes.
Two or three. One for first-party data (Search Console, free), one for technical diagnosis (Screaming Frog) and one for search data and competitors. Fifty-item lists mix up categories that don't replace one another: there are more than 450 SEO tools on the market, but the jobs to cover are still four.
One last thing the industry rarely says: the number of active subscriptions is a sign of disorganisation, not of expertise. In the agencies we have seen up close, the share of licences paid for and opened less than once a month sits steadily between a third and a half, and nobody checks it because the amounts are small taken one at a time. Put a review in the diary for January and July: open the list of recurring payments and, for each item, ask yourself what decision you have made in the last six months thanks to that tool. Items without an answer get cancelled.
