SEOptimer
SEOptimer crawls a website you point it at, scores it against on-page and technical SEO checklist items, and exports a white-label PDF report — built explicitly for agencies reselling audits to clients rather than technical SEOs running deep crawls. Paid plans add keyword tracking, a capped number of backlink lookups, and an 'AI Search Visibility' score for how a site shows up in AI platform answers.
SEOptimer's own crawler scoring on-page checklist items is a well-known, buildable pattern — what's harder to replicate is the white-label report branding and CRM-connected lead-gen forms built for agencies reselling audits, plus the backlink and keyword lookups, whose underlying data source SEOptimer doesn't publicly disclose.
What you lose building it yourself
- ✕White-label PDF branding and an embeddable lead-gen audit form
- ✕CRM integrations (Salesforce, Mailchimp) wired into the embed
- ✕Bundled keyword and backlink search credits per plan
- ✕The 'AI Search Visibility' score across AI platforms
Why people still pay
A single script can brand one PDF for one site; SEOptimer's real audience is agencies who need that report white-labeled and re-generated for many clients on demand, plus an embeddable form wired to their CRM to capture leads — reproducing that multi-tenant workflow is the ongoing product, not the one-time script.
A WHITE-LABEL-FREE AUDIT SCRIPT
An AI coding tool can build a script that crawls a handful of pages, checks common on-page factors, and calls Google's free PageSpeed Insights API for a performance score — genuinely a weekend build. Matching SEOptimer's white-label branding, embeddable lead-gen forms wired to a CRM, and bundled keyword/backlink search credits is real, ongoing engineering aimed at agency workflows, not a single script.
StackPython + requests/BeautifulSoup (or Playwright for JS-rendered pages) for the crawl · Google PageSpeed Insights API (free) for performance scoring · Jinja2 + WeasyPrint (or a spreadsheet template) for the exported PDF report.
Build a Python script that takes a homepage URL and crawls up to 50 same-domain pages (respect robots.txt, 1s delay). Check each page for: title tag presence/length, meta description presence, H1 count, image alt-text coverage, and broken internal links (4xx/5xx). Call Google's free PageSpeed Insights API for the homepage's performance and Core Web Vitals scores. Score the site 0-100 using a simple weighted rule set, and render one branded PDF report (your own logo/colors hardcoded) summarizing the score, worst pages, and a prioritized fix list.

QUESTIONS
Where does SEOptimer's backlink and keyword data come from?
Neither the pricing page nor the product pages disclose whether backlink and keyword numbers are self-crawled or licensed from a third-party data provider — treat it as a bundled data feed with an undisclosed source, not a confirmed proprietary index.
Is there a free plan?
No permanent free tier for the core audit product — SEOptimer offers a 14-day free trial before billing starts, plus a separate page of 60+ smaller free SEO tools that don't require an account.
What is GrowthBar, and is it part of SEOptimer now?
GrowthBar was an AI keyword-research and blog-writing tool that SEOptimer acquired; its site now redirects to a SEOptimer product page describing an in-progress merge, though GrowthBar still sells standalone plans as of this review.
