Cheapest SEO Tools in 2026
A desktop crawl can stay $0. Screaming Frog SEO Spider Free crawls 500 URLs; the paid licence is £199 a year (about $16.60 a month). Ubersuggest Individual is $29 a month, or $290 one-time Lifetime; free is 3 searches a day. Frase has a 7-day trial, then Starter at $39 a month billed yearly ($49 month to month). Moz Standard is $99 a month or $79 billed yearly; Moz also publishes a $49 single-site entry plan. Surfer SEO Discovery is $49 a month billed yearly. Clearscope Essentials is $129 a month with no annual discount on the live card. Ahrefs Starter is $29 a month; the real suite starts at Lite $129. Semrush Pro is $139.95 a month or $117.33 billed annually. Ubersuggest does not replace Ahrefs.
8 tools compared on price, features and fit, with prices checked on vendor pages in September 2026.
Cheap SEO is a desktop crawl or a $29 research seat, not a $129 backlink suite sold as if it were the same product. Screaming Frog SEO Spider Free covers 500 URLs. Ubersuggest Individual is $29 a month. Ahrefs Lite is $129 a month. Those three jobs (crawl, budget research, full index) do not substitute for each other. Toolradar data: Toolradar lists 10,429 published tools as of September 1, 2026, including 230 published seo-tools, 47% of them free or freemium (13 free-only, 94 freemium, 123 paid).
This guide ranks 8 SEO products by standing entry paid price, or by a usable free crawl when that crawl is the real cheap path. We checked screamingfrog.co.uk/seo-spider/pricing, ahrefs.com/pricing, moz.com/products/pro/pricing, surferseo.com/pricing, frase.io/pricing, and clearscope.io/pricing as of September 2026. Moz's page ran a "save up to 40 percent, ends today" banner; standing Standard is $99 a month or $79 yearly. Frase no longer ships a permanent free plan (a 7-day trial, then $39 yearly). Eight picks is the full set. A ninth slug was not invented.
The split that matters is desktop crawl versus content AI versus a full suite. Do not pretend Ubersuggest replaces Ahrefs or Semrush.

| Tool | Starting price | Rating | Best for |

| Moz | From $39/mo | 4.4 958 reviews | Teams that want Domain Authority and a beginner suite, and will quote $79 yearly Standard, not a 40 percent banner |
| Surfer SEO | From $99/mo | 4.8 968 reviews | Writers who need content scores and AI-search guidelines, not a backlink database |
| Clearscope | From $129/mo | 4.9 92 reviews | Content teams that will pay $129 a month to grade long-form against the SERP, and do not need Ahrefs' link index in the same login |

Technical SEOs who can finish a small-site audit at $0, or will pay £199 a year for unlimited crawls on a desktop
- Pro: Free 500-URL crawl with no account, the cheapest technical audit on this list
- Pro: Paid at £199 a year is about $16.60 a month, under Ubersuggest Individual at $29
- Pro: JS rendering, saved crawls, scheduling, and GSC / GA / PageSpeed connectors sit on the paid licence
- Con: Free stops at 500 URLs. A 2,000-URL site needs the paid licence
- Con: Desktop only. There is no browser team workspace like Ahrefs Site Audit
Screaming Frog's pricing is fair, offering a robust free tier for small projects and a competitive annual license.
Solo marketers who want keyword volume and a site audit at $29, and who will not treat it as Ahrefs Lite
- Pro: Individual at $29 a month is the cheapest standing paid research suite on this list
- Pro: Lifetime Individual at $290 is 10 months of $29, a standing toggle rather than a vanished promo
- Pro: Free 3 searches a day plus a Chrome extension quota for one-off lookups
- Con: Backlink and keyword depth trail Ahrefs Lite and Semrush Pro. This is the budget index, not the second-largest crawler
- Con: Lifetime is nonrefundable. Confirm the tool on monthly before you prepay 50 years
Ubersuggest's pricing is quite generous, especially with the lifetime options.
Watch out
No overage fees mentioned, but search limits apply.
Frase
- 4.8 on Capterra (335 reviews)
- 4.8 on G2 (310 reviews)
- 4.3 on SourceForge (67 reviews)
- 1.4 on Trustpilot (49 reviews)
Solo sites that want a content operating loop at $39 yearly and already have a crawler or GSC for technical SEO
- Pro: Starter at $39 a month billed yearly undercuts Moz Standard at $79 yearly and Surfer Standard at $99
- Pro: 7-day trial with no credit card, on Professional's feature set with capped trial quantities
- Pro: Articles, audits, and Content Guard on one loop, which Screaming Frog does not try to be
- Con: Not freemium in 2026. Older 'free Frase' listicles are stale. After 7 days you pay or leave
- Con: Starter is 10 articles and 50 audit pages a month. A real editorial calendar hits Professional at $103 yearly
Frase's pricing is on the higher side compared to some market alternatives, especially for the Starter tier at $39 for only 10 AI-optimized articles.
Watch out
Overage fees for exceeding article limits
Teams that want Domain Authority and a beginner suite, and will quote $79 yearly Standard, not a 40 percent banner
- Pro: Yearly Standard at $79 a month ($950) is cheaper than Ahrefs Lite at $129 and Semrush Pro monthly at $139.95
- Pro: A $49 single-site entry plan is the cheapest Moz card if you truly have one site
- Pro: Free Moz Community still unlocks limited MozBar, Keyword Explorer, and Link Explorer
- Con: A homepage 'save up to 40 percent, ends today' strip is a promo. Standing Standard is $99 / $79
- Con: Backlink depth still trails Ahrefs. Moz is the teaching suite, not the largest index
While the Medium ($143) and Large ($239) tiers offer more robust features, the initial entry points might deter smaller businesses.
Watch out
Overage fees for exceeding limits
Writers who need content scores and AI-search guidelines, not a backlink database
- Pro: Discovery at $49 a month billed yearly is the cheapest standing Surfer rung
- Pro: Standard at $99 yearly adds 360 documents and AI-visibility tracking on 25 prompts
- Pro: Yearly save amounts are published ($120 off Discovery, $240 off Standard), so the monthly premium is visible
- Con: Discovery is a content floor, not Site Explorer. You still need a crawler or a suite for links
- Con: Yearly cards assume you prepay. Month-to-month costs more; confirm the monthly toggle before you compare to Frase $49 monthly
Surfer SEO's pricing is on the higher side, with the Essential tier at $99/month being a significant investment for small businesses.
Watch out
Potential overage fees for content limits
Content teams that will pay $129 a month to grade long-form against the SERP, and do not need Ahrefs' link index in the same login
- Pro: Essentials at $129 a month is a published self-serve card with unlimited users
- Pro: 14-day trial, no permanent free tier, so the $129 figure is the real floor
- Pro: Content grading and topic inventory are the product, clearer than stuffing Semrush Content Marketing into a crawl budget
- Con: No annual discount on the live card we and third-party 2026 reads saw. $129 times 12 is $1,548
- Con: $129 is Ahrefs Lite money without Site Explorer. Do not buy Clearscope to replace a suite
Clearscope's pricing, starting at $129/month for Essentials, is on the higher side compared to some market alternatives, especially for smaller businesses.
Watch out
Overage fees for exceeding credit limits
SEOs who need the Ahrefs index and will pay Lite at $129, or who can live on Free plus Starter at $29 for thin research
- Pro: Ahrefs Free gives Site Explorer and Site Audit on domains you verify, a lasting $0 path for your own site
- Pro: Starter at $29 matches Ubersuggest Individual on headline price for light research
- Pro: Lite at $129 is the first real suite: 5 projects, 6 months of history, 750 tracked keywords, 100,000 crawl credits
- Con: Lite at $129 is 4 times Ubersuggest Individual and about 8 times Frog paid on a monthly equivalent
- Con: Starter is not Lite. Credits and unverified research are thin; most working SEOs still need Lite
Ahrefs is the industry standard for backlink analysis and a serious contender for keyword research, but it remains one of the most expensive SEO tools on the market.
Watch out
Crawl credits are consumed per page crawled in Site Audit. A 50K-page site burns half of Lite's 100K monthly allocation in a single audit cycle. Standard's 500K credits handle larger sites but enterprise sites with 500K+ pages will need Advanced.
Teams that want Semrush's toolkit and will quote $117.33 annual Pro, not a first-month Semrush promo screenshot
- Pro: Annual Pro at $117.33 a month undercuts Ahrefs Lite at $129 and monthly Pro at $139.95
- Pro: Projects, keyword tracking, and a site audit live in one suite, which Frog plus Ubersuggest still split
- Pro: Guru and Business step-ups are published, so the upgrade path is visible
- Con: Monthly $139.95 is not the cheap card. Annual $117.33 is. First-month Semrush ads are promo
- Con: One user on Pro. Extra seats near $45 a month move the bill off the $117 comparison
Semrush is the most comprehensive all-in-one SEO and digital marketing platform, and its pricing reflects the breadth.
Watch out
Keyword tracking limits are per DAY, not per month: Pro gets 500 keywords total in Position Tracking, not 500 new keywords per month. Once you've added 500 keywords, you must remove old ones to add new
What 'Cheapest SEO Tools' Actually Means
A cheap SEO tool is software you can crawl, research, or grade content with, at a published standing price. Screaming Frog SEO Spider is a local crawler: Free at 500 URLs, paid at £199 a year. Ubersuggest is a budget research suite at $29 a month Individual. Frase, Surfer SEO, and Clearscope grade or draft content; they do not replace a backlink index. Moz, Ahrefs, and Semrush are suites with rank tracking, site audit, and (at paid tiers) competitor research.
Ahrefs also sells Starter at $29 a month and Ahrefs Free for verified sites. Starter is not Lite. Ranking Ahrefs at the expensive end of this list is about the suite people mean when they say Ahrefs, starting at Lite $129, not about hiding Starter.
Why a $29 Research Seat Is Not a $129 Index
Ubersuggest Individual at $29 a month and Ahrefs Starter at $29 a month look like the same rung. They are not. Ubersuggest's daily report caps and index depth are built for a solo blog. Ahrefs Lite at $129 buys Site Explorer, Keywords Explorer, and a crawler credit pile that Ubersuggest does not match. Semrush Pro at $117.33 annual is in that same suite band.
Content AI is a third bill. Frase Starter at $39 yearly and Surfer SEO Discovery at $49 yearly optimize pages. They do not crawl 50,000 URLs or show referring domains the way Screaming Frog SEO Spider paid or Ahrefs Lite do. Stacking a $39 writer on a $0 Frog crawl is often cheaper than buying Semrush to "do content."
Key Features to Look For
Free crawl versus paid licence (Essential)
Screaming Frog SEO Spider Free: 500 URLs, no account. Paid: £199 a year, unlimited URLs (memory and disk permitting), JS rendering, saved crawls, scheduling.
Standing suite price versus a 40 percent banner (Essential)
Moz Standard standing is $99 a month or $79 yearly. A 'save up to 40 percent, ends today' strip on moz.com is a promo, not the list card you renew on.
Trial versus permanent free (Essential)
Frase is a 7-day trial, then $39 a month billed yearly. Ubersuggest free is 3 searches a day. Ahrefs Free covers verified sites. Screaming Frog Free is a lasting 500-URL crawl.
Lifetime Ubersuggest versus monthly (Important)
Ubersuggest Individual is $29 a month or $290 Lifetime (50 years per Ubersuggest's own help article). Lifetime is a standing toggle, not a weekend flash sale, and it is nonrefundable.
Ahrefs Starter $29 versus Lite $129 (Important)
Starter is a thin research seat. Lite at $129 is the first suite most SEOs mean. Ahrefs does not run discounts.
Content grader versus backlink suite (Nice to have)
Frase, Surfer, and Clearscope do not replace Ahrefs or Semrush Site Explorer. Clearscope Essentials at $129 a month is a content bill, not a crawl bill.
Mistakes to Avoid
- ×
Treating Ubersuggest Individual at $29 as Ahrefs Lite at $129. Same-looking $29 Starter on Ahrefs is also not Lite. The suite starts at $129.
- ×
Budgeting Moz at 40 percent off. Standing Standard is $99 a month or $79 yearly. The 'ends today' banner is promo.
- ×
Calling Frase freemium. frase.io/pricing as of September 2026 is a 7-day trial, then Starter at $39 a month billed yearly ($49 monthly).
- ×
Buying Clearscope Essentials at $129 to replace a crawler. It grades content. Screaming Frog Free still crawls 500 URLs at $0.
- ×
Quoting Semrush at a first-month promo. Standing Pro is $139.95 monthly or $117.33 annually as of mid-2026 public cards.
Expert Tips
- →
Crawl first on Screaming Frog SEO Spider Free (500 URLs). Pay £199 a year only when the site is larger or you need JS rendering and saved crawls.
- →
If you need keyword volume and can live with a thinner index, price Ubersuggest Individual at $29 or Lifetime at $290 against Ahrefs Starter at $29, then stop. Lite at $129 is the next conversation.
- →
If the job is drafting and scoring pages, compare Frase Starter at $39 yearly, Surfer Discovery at $49 yearly, and Clearscope Essentials at $129 monthly. None of those replace Site Explorer.
- →
Write Moz as $99 / $79 Standard, plus the $49 single-site entry if it still shows on moz.com. Ignore a 40 percent strip unless you are on the checkout that day.
- →
Ahrefs does not discount. If a blog still says 'Ahrefs 20 percent off,' it is stale. Semrush annual at $117.33 is the suite discount that is real.
The Bottom Line
The cheapest usable SEO path in 2026 is Screaming Frog SEO Spider Free at 500 URLs, then the paid licence at £199 a year. Ubersuggest Individual is $29 a month or $290 Lifetime. Frase Starter is $39 a month billed yearly after a 7-day trial. Moz Standard standing is $99 / $79 yearly, with a $49 single-site entry. Surfer SEO Discovery is $49 yearly. Clearscope Essentials is $129 a month. Ahrefs Starter is $29; the suite starts at Lite $129. Semrush Pro is $139.95 monthly or $117.33 annually. Ubersuggest does not replace Ahrefs.
Frequently Asked Questions
What is the cheapest SEO tool in 2026?
Screaming Frog SEO Spider Free crawls 500 URLs at $0. The cheapest standing paid technical licence on this list is Frog at £199 a year. The cheapest standing paid research suite is Ubersuggest Individual at $29 a month, or $290 Lifetime. Ahrefs Starter is also $29, but Lite at $129 is the first full Ahrefs suite.
Does Ubersuggest replace Ahrefs?
No. Ubersuggest Individual at $29 is a budget keyword, audit, and backlink snapshot. Ahrefs Lite at $129 is a different index, credit pile, and Site Explorer. Use Ubersuggest when $29 is the budget. Use Ahrefs when you need that crawler. Ahrefs Free still covers your verified site at $0.
Is Frase still free?
No permanent free plan. frase.io/pricing as of September 2026 offers a 7-day trial with no credit card, then Starter at $39 a month billed yearly or $49 month to month. Older listicles that call Frase freemium are stale.
Is Moz $99 or $49?
Standard is $99 a month, or $79 a month billed yearly ($950 the first year) on moz.com/products/pro/pricing as of September 2026. Moz also publishes a $49 single-site entry plan. A 'save up to 40 percent, ends today' banner is promo, not standing Standard.
Why only 8 tools?
Those 8 slugs cover crawl, budget research, content AI, and the two major suites. A ninth tool was not invented to pad the list. Clearscope, Ahrefs, and Semrush already mark the expensive end.
