Semrush and Ahrefs are the expensive suites agencies buy for keyword, competitor, and (on Semrush) broader marketing reports. Screaming Frog is the cheap desktop crawl (free 500 URLs; paid license for real sites). Surfer SEO, Clearscope, and Frase are content-brief tools you should not confuse with a backlink index. Moz is the gentler all-in-one. Ubersuggest is the low-end keyword rung, not an agency suite.
Ranked for multi-client reporting, crawl budget, and content briefs, not for a single blog's free quota.

Agency SEO is a reporting and throughput problem. You need projects per client, crawl capacity for sites that are not 400 URLs, and briefs a writer can follow without a strategy call every time. A free daily search quota is not that stack. 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 tools for agency work: multi-client reporting, crawl budget, and content briefs. Semrush and Ahrefs are the expensive suites (Pro and Lite in the low $100s a month, Guru and Standard in the mid $200s, Business and Advanced near $450 to $500). Screaming Frog is the cheap desktop crawl that those suites do not replace. Surfer SEO, Clearscope, and Frase write and score pages. Moz is the third suite. Ubersuggest is the low-end.
If you run one site, start with Google Search Console and a single suite trial. If you run twelve client properties, the question is which suite plus which crawler plus which brief tool, not which free Chrome extension.

Best for: Agencies that need white-label reporting, multiple projects, and SEO plus PPC-adjacent research in one login
- Pro: Projects, reporting, and a wider marketing feature set than a links-only story
- Pro: Pro around $139.95 a month (500 keywords, 5 projects); Guru around $249.95; Business around $499.95
- Pro: Content and competitive templates sit in the same vendor as ranks
- Con: You will pay for modules you never open if you treat it as 'the Ahrefs plus extras' bundle
- Con: Backlink index is the usual reason people still keep Ahrefs anyway
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: SEO 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
- Starting price
- From $29/mo
- Free plan

Best for: SEO teams that sell link research, content gap, and Site Explorer as the core of the retainer
- Pro: Site Explorer and the backlink index are why agencies keep paying suite prices
- Pro: Content gap and competitor views are faster than rebuilding the same study in a crawler
- Pro: Webmaster Tools remains a free verified-site path for properties you own
- Con: Lite at about $129 a month is already an agency line item; Advanced near $449 is a second line item
- Con: Reporting and PPC extras trail Semrush, which is why shops buy both and then regret it
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.
Screaming Frog
Desktop crawler. Free Lite is 500 URLs. Paid license is the cheap way to crawl a real client site.
- Starting price
- From $23.25/mo
- Free plan
- Yes
- Rating
- 4.8 (218 reviews)
Best for: Technical SEO on client sites where a sampled cloud audit is not enough
- Pro: Lite crawls 500 URLs with no account, enough to demo, not enough for most retainers
- Pro: Paid license unlocks JavaScript rendering, saved crawls, scheduling, and sites past 500 URLs
- Pro: Flags broken links, redirects, duplicate titles, canonical issues, and index bloat on your machine
- Con: Desktop-only; there is no browser team workspace like a suite
- Con: The 500 URL cap makes Lite unusable as the only crawl on a real client WordPress install
Screaming Frog's pricing is fair, offering a robust free tier for small projects and a competitive annual license.
Surfer SEO
Content briefs and on-page editor. Essential around $89 a month for 30 articles. Not a backlink suite.
- Starting price
- From $49/mo
- Free plan
- No
- Rating
- 4.8 (968 reviews)
Best for: Content teams that need a scored brief a writer can open without a strategist on the call
- Pro: Content editor and briefs are the reason agencies add a fourth login next to a suite
- Pro: Essential around $89 a month (30 articles) and Scale around $129 (100 articles) undercut a second suite seat
- Pro: Google Docs and WordPress paths keep the score in the draft, not in a PDF nobody updates
- Con: No backlink index and no replacement for Screaming Frog on technical debt
- Con: Recommendations can feel like a term-stuffing checklist if you follow them blindly
Yearly billing is paid upfront and saves up to about 17%.
Watch out
Advertised prices assume yearly billing paid upfront; monthly costs about 17 to 20% more

- Rating
- 4.5 (350 reviews)
Best for: Agencies that want a simpler suite and a metric clients already recognize (DA)
- Pro: Pro around $99 a month is the cheaper suite floor versus Ahrefs Lite or Semrush Pro
- Pro: Domain Authority is a number clients already put in decks
- Pro: MozBar and learning resources shorten junior onboarding versus Semrush's surface area
- Con: Backlink depth trails Ahrefs, which is why link-heavy retainers still pay Ahrefs
- Con: Reporting and project limits still push you up a tier as the roster grows
This pricing structure is best suited for established businesses or agencies with a clear need for comprehensive SEO data and a budget to match.
Watch out
Overage fees for exceeding limits
Clearscope
Premium content grader for long-form teams. No crawl, no backlink index.

- 4.9 (92 reviews)
Best for: Retainers that ship researched long-form and will pay more than Surfer for a tighter grade
- Pro: Content grading and SERP term coverage are the product, not a side tab
- Pro: Google Docs and WordPress integrations match how editors already work
- Pro: Trusted on senior content teams that outgrew a cheaper scorer
- Con: Premium team pricing; wrong buy if you only needed Ubersuggest ideas
- Con: No backlink analysis and no technical crawl
It's best suited for established content teams and agencies with a clear ROI from SEO.
Watch out
Overage fees for exceeding credit limits
Frase
Research-and-draft content tool. Free plan was cut; treat current tiers as paid research seats.
- 4.8 on Capterra (335 reviews)
- 4.8 on G2 (310 reviews)
- 4.3 on SourceForge (67 reviews)
- Starting price
- From $39/mo
- Free plan
- Yes
- Rating
- 4.0 (761 reviews)
Best for: Agencies that want SERP research and a first draft in one content login
- Pro: SERP clustering and brief generation sit next to a draft, which cuts a second research tab
- Pro: Cheaper than running Clearscope plus a separate writer tool on small retainers
- Pro: Useful when the deliverable is a briefed article, not a crawl report
- Con: The old permanent free tier is gone; Frase is trial-then-paid as of the 2026 free-SEO check
- Con: Draft quality still needs an editor; a brief is not a published page
This pricing is best for small to medium businesses with a consistent need for AI-driven content optimization.
Watch out
Overage fees for exceeding article limits
Ubersuggest
Low-end keyword and audit rung. Free is 3 searches a day. Not an agency suite.
- 4.4 on Trustpilot (577 reviews)
- 4.2 on G2 (160 reviews)
- 4.4 on Capterra (93 reviews)
- Starting price
- From $12/mo
- Free plan
- Yes
- Rating
- 4.3 (830 reviews)
Best for: Pitches, intern research, and tiny retainers that cannot open Ahrefs Lite yet
- Pro: Free account: 3 searches or reports a day, no card, plus extra Chrome-extension lookups
- Pro: Keyword volume, difficulty, content ideas, and a basic audit in one cheap login
- Pro: Lifetime-licence option exists for buyers who refuse another monthly suite
- Con: 3 searches a day dies in one research session; this is not multi-client reporting
- Con: Volume and link data trail Ahrefs and Semrush, which clients will notice on competitive categories
Ubersuggest's pricing is quite generous, especially with the lifetime options.
Watch out
No overage fees mentioned, but search limits apply.
What Agency SEO Software Actually Covers
Three jobs get billed as 'SEO tools.' Suites: keyword research, rank tracking, competitor gaps, backlinks, site audit, and a client PDF. That is Semrush, Ahrefs, and Moz. Crawlers: a full HTML pass for status codes, canonicals, index bloat, and render issues. That is Screaming Frog on the desktop (Lite 500 URLs free; paid annual license for real crawl budget). Briefs: SERP terms, outline, and an editor score. That is Surfer SEO, Clearscope, and Frase.
Ubersuggest does a thinner version of keyword and audit work at a consumer price. It is on this list so agencies know the low-end, not so they replace Ahrefs with it on an enterprise retainer.
White-label and project limits decide whether a suite is an agency product. Semrush has long sold that story. Ahrefs is the backlink and competitor database people pay the suite premium for.
Why Two Suites and No Crawler Is a Bad Stack
Buying Ahrefs and Semrush together is a common agency bill north of $3,000 a year before seats and add-ons. The overlap on keywords and ranks is large. The usual split, if you buy two, is Ahrefs for links and gaps plus Semrush for reports and PPC-adjacent views, not two full suites for every junior.
Crawl budget is the other hole. Cloud audits sample. Screaming Frog on a laptop (or a box in the office) walks the site you actually shipped. The free 500-URL cap is a demo. Client WordPress installs with 8,000 URLs need the paid license (about £199 a year on older public figures; confirm screamingfrog.co.uk).
Content tools do not invent links. Surfer SEO at a lower monthly than a suite is for briefs. Clearscope is the premium grader. Frase is the research-and-draft lane. None of them replace a crawl when the client is losing indexation to parameter URLs.
Key Features to Look For
Projects and client reporting (Essential)
How many properties, keywords, and white-label PDFs you get before the next suite tier. Semrush sells this harder than Ahrefs.
Crawl budget you control (Essential)
Screaming Frog paid license versus a sampled cloud audit. Free Frog at 500 URLs is not an agency crawl.
Content briefs as a separate SKU (Essential)
Surfer SEO, Clearscope, and Frase. Do not expect Ahrefs to be your editor.
Suite price honesty (Important)
Ahrefs Lite and Semrush Pro live in the low $100s a month. Advanced and Business live near $450 to $500. Ubersuggest is the cheap rung.
Backlink index versus Domain Authority (Important)
Ahrefs for link research. Moz for DA as a client-facing metric. They are not the same database.
Writer workflow (Nice to have)
Google Docs or WordPress plugins on Surfer, Clearscope, and Frase. A CSV from a suite is not a brief.
Mistakes to Avoid
- ×
Paying for both Ahrefs and Semrush on every junior seat. That is two expensive suites. Pick one suite, add Screaming Frog, add one brief tool.
- ×
Using Screaming Frog Lite (500 URLs) as the only crawl on a client site with thousands of URLs.
- ×
Treating Surfer SEO, Clearscope, or Frase as a replacement for a backlink index.
- ×
Pitching Ubersuggest as the agency platform because the monthly number looks kind.
- ×
Ignoring project and keyword caps on Semrush Pro or Ahrefs Lite until the fifth client will not fit.
Expert Tips
- →
Default stack: one suite (Semrush or Ahrefs), Screaming Frog paid, one brief tool (Surfer SEO for volume, Clearscope for flagship pages).
- →
If the client already quotes Domain Authority in the RFP, Moz can be the suite. If they quote referring domains, pay Ahrefs.
- →
Run Frog on staging and production before you write the technical deck. Cloud audits miss parameter bloat.
- →
Put Frase or Surfer on the writer seat. Keep the suite login on the strategist seat.
- →
Use Ubersuggest for a same-day keyword sanity check. Move the real study into Ahrefs or Semrush before the proposal goes out.
The Bottom Line
Semrush and Ahrefs are the expensive suites. Screaming Frog is the cheap desktop crawl (500 URLs free; paid for real crawl budget). Surfer SEO, Clearscope, and Frase are content briefs. Moz is the gentler third suite. Ubersuggest is the low-end, not the retainer platform. Buy by job: reporting, crawl, brief. Do not buy two suites and zero crawler.
Frequently Asked Questions
What SEO tools should an agency buy in 2026?
One expensive suite (Semrush for reporting and broader marketing data, or Ahrefs for backlinks and competitor research), a paid Screaming Frog license for crawls past 500 URLs, and one content-brief tool (Surfer SEO, Clearscope, or Frase). Ubersuggest is optional for cheap keyword checks.
Do I need both Ahrefs and Semrush?
Usually no. They overlap on keywords and ranks. Buy both only if you have a written split (links in Ahrefs, client PDFs and PPC-adjacent views in Semrush) and the budget for two suite bills in the low $100s to $500 a month each.
Is Screaming Frog enough without Ahrefs?
No. Screaming Frog crawls HTML. It does not replace a backlink index or keyword database. It is the cheap desktop crawl next to a suite, not instead of one.
Which content tool is best for agency briefs?
Surfer SEO for volume briefs at a lower monthly (Essential around $89). Clearscope for premium long-form grading. Frase for research-plus-draft in one login. None of them crawl the site or score backlinks.
Is Ubersuggest good enough for clients?
For a tiny site or a same-day keyword check, yes. For multi-client reporting and competitive link work, no. It is the low-end on this list on purpose.
