8 Best Cheap SEO Tools in 2026: Picked by What You Need

Ubersuggest Individual costs $29 a month billed monthly, $192 a year, or $290 once for lifetime access, and it covers one user and one project with 150 searches a day, 125 tracked keywords and 1,000 page scans. Keyword research, rank tracking, site audits, backlinks and AI tracking all sit in the same account, and seven $5 add-ons let you buy extra searches, keywords or a project instead of jumping to a higher tier.

The catch is the free plan and the lifetime fine print. The free account allows about three searches a day, which is a demo, not a workflow. The lifetime purchase excludes most AI features and is non-refundable, and yearly plans have no trial and no refund either. Business, at $49 a month, is the real floor once you run more than one site.

Mangools Basic costs $49 a month, or $29.90 a month billed annually, and it includes the whole suite: KWFinder for keywords, SERPChecker for results pages, SERPWatcher for ranks, LinkMiner for backlinks and SiteProfiler for domain checks. Higher tiers only raise limits, so the cheapest plan never hides a feature behind a paywall. Basic covers 100 keyword lookups a day and 200 tracked keywords, which is enough for one or two small sites.

The catch is that the limits are the product. Basic allows one login and 200 tracked keywords, so a second site or a teammate means Premium at $44.90 a month billed annually. There is no site audit, so technical checks need another tool, and the backlink data comes from Majestic rather than a first-party index.

Ahrefs Starter costs $29 a month and opens the door to the biggest backlink index in this list, with Site Explorer, Keywords Explorer, Site Audit and Rank Tracker included. It covers one unverified project plus unlimited verified projects for domains you own, with 50 tracked keywords. For occasional research on your own sites, it is the cheapest way to see Ahrefs data.

The catch is the credit meter. Starter gives 200 report credits a month, and one disappears every time you open a report or apply a filter, so heavy research burns through it in days. There is no free trial, extra users cannot be added on Starter, and Lite at $129 a month is the real floor for daily use.

WebCEO Solo costs $36 a month, or $32 a month billed annually, and it packs 24 tools into one account: keyword research, rank tracking, audits, internal links, backlinks, social and PPC. One project covers 100 keywords, 1,000 audited pages and 1,000 analyzed backlinks, with weekly automated scanning. For a single site owner who wants breadth over depth, it is a lot of tool for the money.

The catch is the ceiling. Solo covers one project and one user, so a second site means Startup at $119 a month. Rank tracking covers only the Top 50, and there is no free plan, only a 14-day trial. The interface shows its age next to Mangools or Ahrefs, and the learning curve is steeper than the price suggests.

SpyFu Basic costs $29 a month billed annually, or $39 monthly, and it gives unlimited search results and data exports, 100 domain overviews a day and six months of history. The database covers rival keywords, ad spend and backlinks across 109 million domains, and there is no free plan, only a 30-day money-back guarantee. For competitor research alone, nothing else here is this cheap.

The catch is scope. SpyFu has no site audit, no on-page grader and no content tool, so it cannot be your only SEO tool. Basic caps exports at 10,000 rows, Pro + AI at $119 a month removes the caps and adds API access, and the sales-lead lists are thin outside the US.

Ranktracker Launch costs $39 a month, or $31.20 a month billed annually, and it tracks 500 keywords a day with five competitors per project, plus a keyword finder, SERP checker, backlink monitor, web audit and AI article writer. Every plan includes unlimited projects, unlimited users and unlimited on-demand reports, so the bill never grows with your team.

The catch is that Launch is a rank tracker first and a suite second. The keyword database and backlink data are thinner than Semrush or Ahrefs, and the 7-day trial is your only evaluation window: there is no free plan and no refunds during the current promotional period. Growth, at $89 a month, is the step up for 1,000 keywords a day.

Moz Pro Starter costs $49 a month, or $39 a month billed annually, and it is the cheapest entry point among the three big suites. One user, one site, 50 tracked keywords and 5,000 pages crawled a week, with the keyword tools, site audit and Domain Authority that clients still ask about. The interface is the plainest here, so a beginner gets moving fast.

The catch is how thin Starter is. Fifty keywords and one campaign cover a single small site and nothing else, and there is no free trial on Starter. Standard, at $99 a month, is the realistic floor, with three sites and 300 keywords, and extra seats cost $49 a month each.

Serpstat Individual costs $69 a month, or $50 a month billed annually, and it covers five projects, 100 searches a day and 10,000 position checks a month. Team, at $129 a month or $100 billed annually, adds three users, unlimited projects, 500 searches a day and API access, which is the cheapest API in this list outside SpyFu Pro + AI.

The catch is the monthly price. The $50 figure is the annual rate; paying month to month costs $69, which puts it above Mangools and Ubersuggest for a solo user. There is no free plan, only a 7-day trial, and the backlink index is smaller than Ahrefs or Semrush.
