Sellable URL — eligibility estimate

Score 0-100 across 7 axes: indexability (HTTP 200 + no noindex), editorial substance (≥ 500 words), structure (1 H1 + multiple H2), link profile (reasonable external density), brand signals (Organization Schema or OG site_name), cleanliness (few scripts/iframes), freshness (detectable recent date). Each axis carries its weight — a site missing 1 non-critical axis stays viable.

The tool is conservative, as we are when accepting a URL on the Stringer network. It penalizes pages without H1/H2 (often landing pages without editorial body), short pages (< 500 words = not enough semantic context to carry a link), and the absence of brand signals (Organization Schema or og:site_name) which raises an E-A-T concern. If you know one of these axes is intentionally absent (category page, home page), look at the other axes in isolation.

Ahrefs and Majestic measure external health (RD, TF/DR, existing backlink profile). This tool measures the editorial health of the page itself — the prerequisite question, before even looking for a placement. You can have a DR 50 site where 80% of pages are empty landing pages, not eligible. And a DR 25 site whose every article is a solid editorial cocoon, perfectly eligible.

If your page is eligible: you know it can carry an outbound editorial link without dragging quality perception. To buy an inbound link pointing to this page, we can handle that on the Stringer network — the page is credible enough to be worth it. If not eligible: before investing in backlinks, fix the structure (add H2, lengthen the text, remove noindex) — otherwise injected authority dilutes.
