Flat seat subscriptions versus metered usage credits: a comparison for SEO tool buyers
Compare flat seat plans from Semrush, Ahrefs and Moz with metered credits from DataForSEO, SerpApi and AccuRanker. See real prices and limits before buying.
What to take away
- Flat seat plans suit small teams and agencies doing steady hands-on work: you pay for named users and get caps on keywords, projects and reports.
- Metered credits suit developers, bulk data pulls and burst projects, because there is no seat fee and the bill follows requests.
- For a three-person team needing 5,000 SERP checks, Semrush Guru plus extra users costs about $339.95, against $75 for a metered SerpApi plan.
- List prices below are in USD, GBP or EUR and are indicative, so confirm the figure on the vendor page.
- Decide on cost per unit of work, not the headline number.
What each vendor actually charges
Vendor price claims count as comparative advertising, so the ASA advertising codes apply when a provider calls itself cheapest. Figures are list prices in the currency shown, taken from public pricing pages at the time of writing.
| Vendor | Model | List price | Unit | Included limits |
|---|---|---|---|---|
| Semrush | Seat | $139.95 (Pro) to $499.95 (Business) monthly | named user | extra user about $45 a month |
| Ahrefs | Seat | $29 (Starter) to $1,499 (Enterprise) monthly | named user | extra user about $50 on Lite; API sold in units |
| Moz Pro | Seat | $49 to $599 (Premium) monthly | named user | caps on campaigns and tracked keywords |
| Screaming Frog | Seat, desktop | £199 a year | named user | free version crawls 500 URLs |
| Sitebulb | Seat, desktop | monthly or annual per user | named user | fixed cost, no credit meter |
| DataForSEO | Metered | pay as you go per call | API call | no seat; SERP, keyword and backlink calls |
| SerpApi | Metered | from $75 monthly | search | 100 free searches monthly; $75 covers 5,000 |
| Majestic | Mixed | £39.99 (Lite) and £79.99 (Pro) monthly | plan plus API units | API units sold separately |
| AccuRanker | Metered by keyword | from about €109 monthly | tracked keyword | 1,000 keywords, not named users |
Seat prices spread widely. Semrush lists Guru at about $249.95 and Business at about $499.95 a month. Ahrefs runs from $29 to $1,499, and an extra user on Lite costs about $50.

Moz Pro starts at $49 a month and reaches $599 for Premium, with campaigns and keywords capped by tier. Crawl jobs consume allowance, and the crawling and site audit resources explain which tasks burn units.
Metered vendors work differently. DataForSEO sells pay-as-you-go calls for SERPs, keywords and backlinks with no monthly seat. SerpApi offers 100 free searches a month and charges from $75 for 5,000. If you buy data by the call, our rank tracking APIs buyer's guide lists the contract terms worth checking.
Majestic lists Lite at £39.99 and Pro at £79.99 a month, with API units sold separately. AccuRanker prices by tracked keyword, from around €109 a month for 1,000 keywords rather than by named user.
Metered vendors sell through an API, and what an API is helps non-technical buyers read their pricing pages.
Example: three people, one month, two models
Illustrative figures below use the list prices above, not quotes. The team needs about 5,000 SERP checks and some crawl work a month.
On the seat route, Semrush Guru at about $249.95 plus two extra seats at roughly $45 each gives about $339.95 a month before overage. Screaming Frog adds £199 a year, about £16.60 a month.
On the metered route, SerpApi at $75 covers 5,000 searches with no seat fee, so all three share one allowance. The limit is scope: it returns search results and does not replace an audit suite.
Which model wins for which buyer
A flat seat plan wins for small teams and solo consultants with steady work. Caps keep the bill predictable, and the interface does the analysis. Our guide to choosing an SEO tool for a small UK agency explains how to size the tier.
Agencies usually need both. Seats cover the client-facing team, while credits pull large volumes of SERP data for research. Keep software access, data credits and human work on separate contract lines.
Developers and high-volume users should default to metered credits, because there is no seat to pay for and the cost tracks requests.
How do I compare vendors on price?
Normalise seats, credits and service days into one monthly figure for your expected volume.
- Write down monthly volumetracked keywords, SERP checks and API calls.
- Find the cheapest tier that covers it, then add extra user fees and overage rates.
- Divide annual licences by 12 so desktop tools sit in the same column.
- Seat route total = plan price + extra seats + overage. Metered total = expected units x unit price.
- Divide each total by monthly volume to get cost per check.
A three-seat plan at about $339.95 for 5,000 checks is about 6.8 cents per check. The same volume on SerpApi costs $75, or 1.5 cents. Compare only when scope matches.
If you report positions monthly, visualising rank tracking data in Data Studio shows how to reuse one data pull across several client reports.
Common questions
Can I combine a seat subscription with API credits or service fees?
Yes, and many agencies do. Ask for separate lines for software access, data credits and human work, then check whether API calls are included or billed in units.
Are free tiers a real alternative or just a demo?
Treat them as a test of fit. Ahrefs Webmaster Tools gives verified owners free audit and backlink data with limits, and Google Search Console caps automated checks by quota. If you cannot finish a real task without upgrading, budget for the paid tier.
How do I know the quoted prices are current?
Check the vendor's own pricing page before you sign. Tier names change, and these are list prices rather than negotiated rates.
