How big can your site be before Semrush Site Audit needs a pricier plan?

Summary

A 15,000-page site audited weekly fits Semrush One Starter’s crawl allowance; auditing it daily needs Advanced among the three standard bundle tiers. Starter covers 100,000 pages a month and 20,000 per audit, Pro+ covers 300,000 and 20,000, and Advanced covers 1,000,000 and 100,000. Check both ceilings, plus JavaScript rendering, before choosing.

Two crawl ceilings, not one

Plan	Pages/month	Pages/audit	What it changes
Starter / Pro	100,000	20,000	A small enough site can be audited repeatedly
Pro+ / Guru	300,000	20,000	More frequent audits, same single-audit ceiling
Advanced / Business	1,000,000	100,000	Larger sites in one pass

Scroll horizontally to see all columns on a narrow screen.

Source: Site Audit limits. The names after the slash are the included SEO Toolkit tiers. A free account allows 100 pages a month and per audit. Unused monthly pages do not carry over. Moving from Starter to Pro+ does not make a 50,000-page site fit into one audit.

For the $139 “SEO” card on the current pricing page, confirm which SEO Toolkit tier your purchase grants. The help publishes Pro, Guru and Business limits with separate standalone pricing; do not infer the allowance solely from the word “SEO.”

A 15,000-page store, audited at different frequencies

Each crawl uses monthly capacity again. Assuming every run crawls all 15,000 pages:

Frequency	Monthly pages	Smallest fitting bundle tier
Weekly, 4 or 5 runs	15,000 × 4 = 60,000; × 5 = 75,000	Starter
Twice weekly, 8–10 runs	120,000–150,000	Pro+
Daily in a 31-day month	15,000 × 31 = 465,000	Advanced

Scroll horizontally to see all columns on a narrow screen.

These examples leave out other sites and reruns, which use the same account allowance. Twice-weekly schedules can produce ten runs in a long calendar month, so eight or nine is not a safe maximum.

On monthly billing, the plan charges are $199, $299 and $549 before tax. Moving from weekly Starter to daily Advanced adds $549 − $199 = $350 per month. You can also reduce the crawl scope or frequency if that still covers the pages you need to inspect.

A larger site can be inspected in sections

The configuration guide lets you restrict a crawl to a subdomain or subfolder. If a 50,000-page site can be divided into three non-overlapping sections of no more than 20,000 pages each, auditing every section weekly uses 50,000 × 4 or 5 = 200,000–250,000 pages a month. That fits Pro+ if there are no other crawls consuming the allowance.

You receive separate section reports, not a single whole-site audit. Advanced is the standard bundle tier for a single pass through those 50,000 pages. Its 100,000-page per-audit ceiling also has a limit: a 150,000-page site still does not fit in one standard audit.

Rendering can decide the tier before page count

JavaScript rendering lets the crawler read content that appears only after scripts run. Site Audit makes it available on Guru and Business, corresponding to Pro+ and Advanced. A small site that requires this rendering can therefore need Pro+ even if its page totals fit Starter. AMP checks are Business/Advanced only.

AI crawler-access checks are a separate issue. The current AI feature guide says these are available with any Site Audit, including free and paid plans. The standalone AI Visibility Toolkit lists checks for up to 100 pages. Buying AI Visibility alone is not a replacement for the larger SEO crawl allowance.

Budget for the schedule you intend to keep

Choose Starter when both crawl ceilings fit and JavaScript rendering is unnecessary. Choose Pro+ for more monthly crawls or required rendering, while retaining the 20,000-page per-audit ceiling. For a larger single report or the 465,000-page daily example, Advanced fits the published limits. A team that only needs occasional section checks may spend less by narrowing the crawl than by upgrading for every URL on the site.
