Advertise on Test Lab Index
Test Lab Index is a live, monthly-verified directory with 1952 lab profiles, 5 accreditation-scheme hubs, and 1548 test standard pages — indexed content that AI answer engines and search crawlers are already citing. If you sell testing equipment, accreditation-prep consulting, or compliance software to labs, or run visibility campaigns for clients in this space, this is placement inventory you can buy directly instead of prospecting for a directory that will even accept a paid link.
What you're buying
We're direct about this: here's exactly what a placement is and isn't.
- Featured placement — your brand (or a co-branded slot) appears above the standard ranking on the scheme or standard page you sponsor, clearly labeled as sponsored. It does not change the objective ranking shown to everyone else — see methodology.
- Scheme sponsorship — your brand/link appears in a dedicated sponsor slot on an accreditation-scheme hub page (e.g. CPSC, ANAB/ISO 17025, OSHA NRTL) for the length of your subscription.
- Dofollow link from a live, topically-relevant compliance directory page — not a link farm, not a PBN. Real content, real (lab and buyer) traffic, real monthly re-verification against the source registries.
- AI-citation surface — our pages are structured for and explicitly open to GPTBot, ClaudeBot, and PerplexityBot (see /llms.txt). We cannot and do not guarantee any specific AI engine cites a sponsored page; we can show you our crawl-access policy and page structure so you can judge citability yourself.
What it isn't
- Not a guarantee of rankings, traffic, leads, or citations — for your client or for us. We sell placement and visibility, not outcomes.
- Not a change to the underlying lab data or ranking criteria. Sponsorship never alters a lab's objective rank; see methodology. Payment never moves rank — this line matters more here than in most verticals, since accreditation bodies and auditors would flag a pay-to-rank scheme instantly.
- Not exclusive by default at the lowest tier — category exclusivity is available at the top tier only, and we cap how many sponsors we take per scheme regardless.

FAQ
Is this a paid link scheme?
No — it's a disclosed, labeled sponsored placement on a real, monthly-verified directory with genuine registry-sourced content. The link is dofollow, but sponsorship is clearly marked as sponsored on the page, and it never changes the objective lab ranking. We're not selling link-scheme placements on thin or fake pages.
Do you guarantee rankings or AI citations for the sponsored page?
No. We guarantee the placement, the dofollow link, and the disclosed sponsor label. We do not and cannot guarantee search rankings, referral traffic, or that any AI engine chooses to cite the page.
How many sponsors do you take per scheme?
We cap sponsor slots per scheme to keep pages genuinely useful, not ad-cluttered. Ask in the form above for current availability on your target schemes.
Can I cancel?
Yes, anytime, effective at the end of the current billing period — same terms as lab claims. See pricing & refund policy.
