AI SEO site audit tool for agencies
Per-page action plans you can actually execute - prioritised by impact, white-labelled, with the AI search analysis Semrush and Ahrefs do not do.
Built for the SEO landscape as of 2026: AI search engines now drive a growing share of discovery, and the audit tools agencies rely on were designed for the pre-AI Google. Crawl your domain, batch-scan every page, ship branded reports your clients can really understand. 99 metrics across 20 dimensions in one per-page report - AI Search Readiness (40% weight) plus every traditional SEO ranking factor.
Modern audit for modern search - replaces 80% of what agencies pay Semrush + Ahrefs for, at a fraction of the cost. Use OptimAI for the audit work that actually moves the needle.
10 free Pro page scans (160 credits). Full Pro access. Domain crawling, metrics, keywords, and executive summaries included free. You only pay for page scans.
How the AI SEO site audit works
Five steps from domain to board-ready report
Add your domain
Enter any domain. We crawl your sitemap and internal links, discovering up to 500 pages. See your full site structure as an indented page tree - orphans, missing sitemap entries, broken links.
See your domain intelligence
Backlinks, referring domains, domain rank, every keyword you rank for in Google, page 2-3 opportunities, estimated traffic and traffic value. All included - no extra cost.
Batch scan your pages
Select pages from the tree, hit scan. Each page gets 99 metrics across 20 dimensions plus AI visibility scoring. Dynamic budget display shows costs as you select. 10 pages free.
Get your executive summary
AI-generated strategic report for your domain. Score distribution, strongest and weakest pages, content gaps, keyword cannibalisation, and prioritised recommendations. Generate as many as you want - free.
Track and improve
Rescan pages after making changes - your action plan ticks off what's resolved and flags what still needs work. Track score history on every page. Watch AI citation trends across Google, ChatGPT and Perplexity. Share reports with your whole team. Export white-label PDF reports for clients.
Unlimited reports
Once pages are scanned, generate unlimited segmented executive summaries - by section, URL group, or label. Each one ships as a white-label PDF carrying your brand, not ours. Slice your data any way you need. No extra cost. Ever.

The Tool Does the Thinking
Semrush gives you dashboards full of charts. You still have to interpret the data, write up what it means, and figure out priorities. OptimAI gives every page a personalised action plan - specific fixes prioritised by impact. Hand it to the client. Done.
Scan, Fix, Rescan - Prove the Work
Every rescan updates the scorecard and tracks what improved. Resolved badges show progress. Your client sees the before and after. No more "trust us, we're working on it" - the numbers speak for themselves.
Unlimited White-Label Reports
Your logo, your colours, your brand. Individual page scorecards and executive summaries - all branded as yours. Generate as many as you want from existing scan data. Monthly client reports at zero extra cost. Semrush charges $20/report/month for this. Ahrefs locks it behind their £799/month Enterprise plan.
Continuous Intelligence
Every scan refreshes keyword opportunities, SERP competitors, AI visibility checks, and action plan recommendations. The intel evolves with your client's site. No stale data, no guesswork - just an updated to-do list every time you rescan.
Unlimited Users, Zero Seat Fees
Share everything across your team via Google or Microsoft domain authentication. Everyone @youragency.com sees the same data. Semrush charges $45-100 per extra user per month. Ahrefs charges £16-80 per seat. OptimAI: free. Always.

Realistic agency usage comparison

Billed monthly whether you use it or not. This is Semrush's best case - annual billing, 1 user, no extras. Add a second seat ($80/mo) or more clients and it climbs fast. You still have to interpret the data yourself - no action plans, no executive summaries, no prioritised recommendations.

Every scan gives you what Semrush and Ahrefs can't
They give you a spreadsheet. We give you a to-do list that updates every time you rescan.
What you'd genuinely keep them for
Honest version: there are two real reasons to keep a Semrush or Ahrefs subscription alongside OptimAI. Knowing which is which is half the battle.
- Daily rank tracking at scale - if your agency runs continuous client rank monitoring across hundreds of keywords, that's their core product and we don't replicate it.
- Deep backlink-building tools - if you're actively running outreach campaigns, link prospecting, or competitor backlink mining, Ahrefs is the specialist tool for that. We surface backlink metrics; we don't replace link-building software.
Everything else - site audit, domain intelligence, AI search visibility, executive summaries, white-label reports, action plans - is OptimAI territory. At a fraction of the cost. With the AI search analysis they don't do at all.
Domain intelligence is free. Page scans are £16 each (£10 rescan). 10 free scans to start. Credits never expire. No lock-in.

Frequently asked questions
Site audit
What does the AI SEO site audit include?
Everything you need to understand a domain's SEO health. We crawl your site (up to 500 pages), build a page tree showing sitemap coverage, provide domain-level metrics (backlinks, referring domains, organic keywords, traffic estimates), let you batch scan pages with 99-metric scoring, generate AI-powered executive summary reports, and track AI citation trends over time.
Site crawling, domain metrics, keyword intelligence, and executive summaries are all free. You only pay for individual page scans.
How many pages can I audit?
Site discovery crawls up to 500 pages per domain. Batch scanning handles up to 100 pages per batch with 3 concurrent scans. Your 10 free page scans are enough to audit the key pages of most small-to-medium business sites.
What are executive summaries?
AI-generated strategic reports for your domain - or any subset of pages. They include score distribution (how many pages are green, amber, red), improvement tracking between scans, your top 5 strongest and weakest pages with commentary, common issues across the site, content gaps, keyword cannibalisation detection, and 3-5 prioritised strategic recommendations.
Once pages are scanned, you can generate as many executive summaries as you want at no cost. Segment by URL group, label, or section. Monthly client reporting without monthly fees.
What does "unlimited segmented reports" mean?
Executive summaries are generated from your existing scan data. That means once you've scanned pages, you can slice the data any way you need - by section (blog vs service pages), by label (Q1 audit vs Q2 audit), by URL pattern - and generate a fresh strategic report each time. No additional credit cost. An agency managing 5 client sites can produce monthly board reports for all of them from existing scans.
Pricing
What exactly is free?
Site crawling and page tree discovery. Domain metrics (backlinks, referring domains, domain rank, traffic). Keyword intelligence (all ranked keywords, page 2-3 opportunities, clusters). Executive summary reports (unlimited). AI citation tracking. Team sharing. CSV export.
You only pay for individual page scans: £16 per new scan, £10 per rescan. That's where the 99-metric scorecard, AI visibility check, AI advisor action plan, keyword opportunities, and SERP intelligence come from.
How does this compare to Semrush or Ahrefs?
Semrush Pro starts at $139.95/month for 5 projects and 1 user. Add white-label reports ($20/report/month), AI visibility tracking ($99/domain/month), and an extra seat ($45-100/month) and an agency managing 5 clients is looking at $845/month - roughly £650/month or £7,800/year. Ahrefs locks white-label behind their Enterprise plan at £799/month.
OptimAI gives you domain metrics, keyword intelligence, site crawling, executive summaries, AI visibility, and citation tracking - all free. You only pay per page scan (£16 new, £10 rescan). An agency managing 5 clients with ongoing monthly rescans spends roughly £1,900/year - 74% cheaper than Semrush. And every scan includes a personalised action plan, keyword opportunities, and AI visibility checks that neither Semrush nor Ahrefs offer at any price. No guesswork - just a prioritised to-do list that updates every time you rescan.
Do credits expire?
No. Credits never expire. Buy them when you need them, use them at your own pace. Automatic refund if a scan fails.
For agencies
Can I white-label reports?
Yes. Customise PDF reports with your own logo, colours, and branding. Both individual page reports and executive summaries support white-labelling. Your clients see your brand, not ours.
Can my team access reports?
Yes. Team access works via Google or Microsoft authentication domain sharing - anyone with the same email domain can view shared reports. No invite flows or per-seat pricing. Collaboration is free.
Do you offer volume pricing for agencies?
Yes. For agencies running high scan volumes we offer custom credit pricing. Book a call and we'll put together a package that works.
