Most agencies end up with three to five audit tools open at the same time. Each one answers a different question, costs a different amount, and generates a different kind of deliverable. That's not a workflow problem — it's a sign that the category is fragmented, and nobody has built the single tool that handles everything an agency actually needs.
Here's an honest breakdown of what's available in 2026, organized by what each category of tool is genuinely good at — and where the gaps are.
Before comparing products, get clear on the two distinct jobs an audit tool does:
Operational auditing — crawling a client's site, surfacing broken links, duplicate titles, redirect chains, and crawl budget waste. This is the technical substrate. You use it after you've signed a client.
Prospecting and lead capture — turning a cold contact into a paying client by showing them their site's problems before you've had a sales call. This is a fundamentally different job: the output has to be readable by a non-technical person, it has to arrive within 30 seconds, and it has to make the agency look competent.
Most tools are built for one of these, not both. Choosing the wrong one for the wrong job is why agencies end up juggling five tabs.
Lighthouse is the reference standard for performance measurement. It runs in Chrome DevTools or via the CLI, and Google PageSpeed Insights exposes the same engine via a free API. If you're debugging an LCP problem or a CLS regression, this is where you start — not because it's the friendliest UI, but because it's the data Google actually uses.
What it doesn't do: brand itself as yours, generate a lead, explain findings to a client who doesn't know what "render-blocking resources" means, or score anything outside of performance and accessibility.
Use the Page Speed Grader to translate Lighthouse output into a client-facing grade — same underlying data, readable deliverable.
Best for: Deep technical crawls of existing client sites. £259/year.
Screaming Frog is the closest thing to an industry-standard operational crawler. You point it at a domain, it crawls every URL, and it surfaces missing meta descriptions, broken internal links, orphaned pages, redirect loops, and duplicate content faster than anything else in the category.
The ceiling is that it's a desktop application. You can't embed it anywhere, white-label it, or hand a prospect a link to run it on their own site. It's a tool for you, not a tool that generates leads for you.
If your workflow involves auditing client sites you've already onboarded, Screaming Frog is hard to beat on depth and price. If you're trying to get new clients in the door, it plays no role in that motion.
Best for: Existing clients in ongoing retainers. $129–$449/month depending on tier.
Both platforms include site audit modules that rival Screaming Frog's coverage — and add backlink data, rank tracking, keyword gap analysis, and competitive benchmarking on top. If your agency is running retainers and needs one consolidated platform, the audit module is a reasonable bonus feature.
What neither does: let you embed the audit experience on your own website, capture leads through it, or generate something a prospect can read without you narrating it. These are enterprise tools designed for agency-to-client reporting, not agency-to-prospect conversion.
The common mistake is paying $449/month for a platform because "it has auditing" when you only needed the audit part. If the rank-tracking and backlink features aren't getting used, you're subsidizing features you don't need.
Best for: White-label reports for existing clients. $29–$99/month.
SEOptimer was the first to productize the white-label audit report. You enter a domain, it runs a quick scan, and you get a PDF or shareable link with your agency's branding. For a long time, this was the only game in town for agencies that wanted a client-facing deliverable without building one themselves.
The gaps in 2026 are real: no AI-generated summary in plain English, no AI-visibility scoring (llms.txt, crawler access, schema completeness), and no embeddable widget that captures leads on your site and routes them to your CRM. The report format is also showing age — it looks like it was designed before mobile-first design was a consideration.
If your only need is a branded PDF to attach to a proposal, SEOptimer still works. If you're trying to use an audit as a top-of-funnel lead magnet on your own site, it's not built for that.
Best for: Agencies who want an embeddable lead magnet. $39–$79/month.
MySiteAuditor's core value proposition is the embeddable widget: drop a form on your website, a prospect enters their URL, and they get a basic audit report while you capture their contact information. This is the right idea.
The execution in 2026 is dated. The reports are technical rather than readable, the AI-visibility scoring is absent, and there's no way to score emerging signals like structured data quality or AI crawler accessibility. The product hasn't changed materially in several years.
Best for: Agencies using audits as a lead-capture mechanism with AI-visibility scoring.
Recon's differentiation is the combination of embeddable lead capture + AI-visibility grading in a single product. You embed a widget on your agency site or landing page. A prospect enters their URL. Within 30 seconds they get a readable, graded report covering performance, SEO, security, mobile, and accessibility — plus an AI-visibility score that no other embeddable tool currently provides.
The AI-visibility score covers signals like llms.txt presence, robots.txt AI-crawler rules, structured data completeness, and content extractability — the signals that determine whether a site appears in ChatGPT, Perplexity, and Google AI Overviews responses. For agencies selling GEO services, this is a concrete differentiator.
What Recon isn't: a Screaming Frog replacement for deep technical crawls, or a Semrush replacement for rank tracking and backlink analysis. It's a prospecting and lead-capture tool that happens to generate high-quality audit data. Use it at the top of your funnel; use the operational tools after the client has signed.

Generic contact form + PDF attachment. Sending a prospect a PDF audit you ran manually doesn't scale. Automating it is the point.
Enterprise platform licenses for audit-only use. If you're not using Semrush's rank tracking or Ahrefs' backlink analysis weekly, the audit module alone doesn't justify the price.
Tools that score only performance. Lighthouse clones that ignore security headers, schema markup, and AI-crawler access are incomplete in 2026. Prospects with clean Lighthouse scores still have conversion-killing issues the tool won't surface.
Non-branded reports. Every deliverable that goes to a prospect should have your agency's name on it. Tools that can't white-label are a missed branding opportunity at the moment of maximum prospect attention.
Buying tools before defining the workflow. An audit tool is only useful if you know when in the sales or delivery process it gets used, who reviews the output, and what action it triggers. Buy the tool after you've sketched the workflow.
Conflating "comprehensive" with "useful for clients." A 200-point technical audit is useful to you. A prospect reading it on a Tuesday afternoon needs five clear problems, a grade, and a reason to reply to your email.
Skipping AI-visibility scoring because it's new. AI search traffic is already measurable. Agencies that can show prospects their AI-visibility score have a concrete opening to conversations that competitors who only discuss traditional SEO can't have.
Letting the free tier do the work of the paid tier. Most audit tools limit crawl depth or hide key signals on free plans. If you're using a free plan to generate prospects, you're showing them an incomplete picture — which undercuts the authority the audit is supposed to create.
Opinionated take: The embeddable lead-magnet audit is the highest-leverage tool for a small agency in 2026. It works while you sleep, it qualifies prospects before a sales call, and it gives you a data-driven reason to reach out. Agencies that are still relying on cold email alone are doing the hard version.
The audit one-liner for agencies: Match your tool to the job — lead capture needs an embeddable, client delivery needs a crawler, and AI-visibility scoring is the differentiator every prospect hasn't heard from your competitors yet.
