1. Semrush: best all-round SEO platform

Semrush is an online visibility platform that combines keyword research, competitor analysis, site audits, rank tracking and AI-search monitoring. It is our top pick because one subscription covers most of what a small team does day to day, and it appears in our directory as Semrush. On its pricing page, shown in pounds to us, the SEO plan costs £95.07 a month billed annually (£113 monthly) and covers 5 websites and 500 keywords tracked daily.

Starter SEO + AI Search is £133.84 a month billed annually (£161 monthly) and adds 50 daily AI prompts. Pro+ is £201.09 billed annually (£242 monthly) with 15 websites, 1,500 keywords, historical data, content optimisation and cannibalisation analysis. Advanced is quote-only. There is a free account with one demo project and 10 reports a day, plus a 7-day free trial; extra users start from £36 a month.

Reviewers broadly favour Ahrefs for backlinks and Semrush for keyword and marketing breadth, though many comparison sites are affiliate-supported and their accuracy figures conflict, so trial both against your own Search Console data.

Pros

• Keyword, audit, tracking and AI-visibility tools in one login
• Free account and a 7-day trial for testing
• Clear annual saving of up to 17%
• Content optimisation unlocks at Pro+

Cons

• 500-keyword cap on the cheapest plan
• Extra users cost from £36 a month
• Content optimisation and historical data need Pro+
• Advanced tier is quote-only

Pricing: Free; SEO £95.07/month billed annually (£113 monthly); Starter SEO + AI Search £133.84 (£161); Pro+ £201.09 (£242); Advanced custom. GBP as shown to us, as of 29 October 2026.

Best for: Marketing generalists, agencies and in-house teams wanting one platform. Visit Semrush.

2. Ahrefs: best for backlink research and power users

Ahrefs is an SEO suite known for its backlink index, Site Explorer and Keywords Explorer, and it is the strongest alternative to Semrush. Its pricing page showed Lite at £99 a month, Standard at £199, Advanced at £359 and Enterprise at £1,199 (annual commitment), with annual billing saving up to 17%. The cheapest listing is a Starter plan at £23 a month plus an Ahrefs Free plan covering your own site.

Lite includes 750 tracked keywords, 150 AI prompt checks, 100,000 crawl credits, six months of historical data and one user; extra users cost £32 a month each. Standard raises that to 2,000 keywords, two years of history and 500,000 crawl credits. API and MCP access come with each tier. Brand Radar, its AI-search tracker, is a separate product from £159 a month.

That history limit matters: on Lite you only see six months of data, so serious competitor research tends to push buyers to Standard at £199.

Pros

• Powerful backlink and competitor data
• Starter at £23 a month for light use
• Free plan covering your own site
• API and MCP access on each paid tier

Cons

• Lite has six months of history and 750 keywords
• Brand Radar AI tracking is an extra product from £159
• Jump from Lite to Standard is £100 a month
• Switching to annual billing means contacting support

Pricing: Starter £23/month; Lite £99; Standard £199; Advanced £359; Enterprise £1,199 (annual commitment); annual billing saves up to 17%. GBP as shown to us, as of 29 October 2026.

Best for: SEO specialists, link builders and agencies who prioritise backlink data. Visit Ahrefs.

3. Mangools: best for beginners and budgets

Mangools is a bundle of five simple SEO tools: KWFinder, SERPChecker, SERPWatcher, LinkMiner and SiteProfiler. Its pricing page showed Basic at $37.70 a month billed annually ($452.40 a year) or $61 billed monthly, Premium at $52.70 ($632.40 a year) or $81 monthly, and Agency at $97.70 ($1,172.40 a year) or $141 monthly, all in USD.

Every plan includes an AI search tracker with 500 monitored prompts, plus API and MCP access. Basic allows 100 keyword lookups and SERP analyses a day, tracks 200 keywords with weekly updates and gives 100,000 backlinks a month. Premium raises that to 500 lookups and 700 keywords, and Agency to 1,200 lookups, 1,500 keywords and daily updates.

There is a 48-hour money-back guarantee, which is short, and the refund does not apply to two consecutive subscriptions. The headline discount for yearly billing is 35% on the page.

Pros

• Beginner-friendly tools at a lower price
• Annual billing cuts Basic to $37.70 a month
• AI prompt tracking included on every plan

Cons

4. Surfer: best for optimising written content

Surfer is a content optimisation platform that scores articles against top-ranking pages and now tracks AI-search visibility; it is listed in our directory as Surfer.

A separate AI Search Analytics plan is $82 a month billed yearly, tracking 50 prompts daily. Higher tiers add internal linking, cannibalisation reports, a content-ideas tool and, at the top, API access and a success manager. Enterprise is custom.

Surfer does not replace a full toolkit with backlink data and large keyword databases, so most users pair it with another tool on this list.

Pros

• Content score guides writers while drafting
• Plans start at $49 a month billed yearly
• Tracks AI-search visibility
• Rank drop detection from Standard

Cons

• Not a full backlink or site-audit suite
• Document limits per plan
• Annual plans are charged for the whole year up front
• Higher tiers jump to $182 and $299

Pricing: Discovery $49/month, AI Search Analytics $82, Standard $99, Pro $182, Peace of Mind $299, all billed yearly; Enterprise custom. USD, as of 29 October 2026.

Best for: Content teams and writers who need to optimise articles for search. Visit Surfer.

• $49 entry plan for a single site
• Free community account with limited tools
• Clear tier ladder

How we compared these tools

This is desk research, not a lab test. We read each vendor's live pricing page on 29 October 2026, used a browser to read Mangools, whose prices load by script, and ran no tests of data accuracy. Coverage claims such as index sizes are not verifiable by us, so we do not repeat them.

We weighed price transparency and value after year one most heavily (about 35%), then limits such as tracked keywords, history and users (25%), breadth of tools (20%), ease of use and support (10%) and lock-in (10%). More in our marketing tools category.

How to choose

• If you want one tool for most jobs, pick Semrush.
• If you build links or run competitor research, pick Ahrefs.
• If you are a beginner or on a tight budget, pick Mangools.
• If you write a lot of content, add Surfer.
• If you manage one small site and know Moz metrics, pick Moz Pro.
• If you also send marketing email, read our email marketing software guide.

Frequently asked questions

What is the best SEO tool in 2026?

Semrush is our top pick for most people because one plan covers keyword research, site audits, rank tracking and AI-visibility, starting at £95.07 a month billed annually. Ahrefs is better for backlink research, Mangools is cheapest for beginners, Surfer helps optimise content and Moz Pro suits small sites. The best option depends on your keyword volume and budget.

Is Ahrefs better than Semrush?

Neither wins everywhere. Reviewers broadly rate Ahrefs ahead for backlinks and Semrush ahead for keyword breadth and marketing features, but accuracy claims conflict and most comparison sites are affiliate-supported. Ahrefs Lite is £99 a month with 750 tracked keywords, against Semrush SEO at £95.07 billed annually with 500. Trial both against your own Google Search Console data.

What is the cheapest paid SEO tool?

Mangools Basic at $37.70 a month billed annually ($61 monthly) is the cheapest full bundle here, and Moz offers a $49 single-site entry plan. Ahrefs lists a £23 Starter plan with narrower access. Surfer Discovery is $49 a month billed yearly but focuses on content, not backlinks or audits.

Do I need Surfer if I already use Semrush?

Not always. Semrush Pro+ includes content optimisation, so you may not need Surfer. Surfer is stronger as a writing workspace, with a content score, internal linking and AI-search tracking from $49 a month billed yearly. If you publish many articles each month, trial Surfer; otherwise rely on your existing suite.

Can SEO tools track visibility in AI search?

Yes. Semrush lists AI visibility prompts and reports, Ahrefs sells Brand Radar from £159 a month, Surfer tracks prompts across AI models, Mangools bundles an AI Search Watcher with 500 prompts, and Moz tracks 150 prompts on Standard. Prompt limits, platforms and refresh rates differ, so check these on the plan you want.

Which SEO tool suits UK and EU businesses?

Semrush and Ahrefs displayed prices in pounds to us, which avoids exchange-rate surprises, while Mangools, Surfer and Moz price in US dollars. Check VAT, which is usually added at checkout, and each vendor's data processing terms. All five let you target UK search results, but confirm location options for your plan.
