Built to rank — ranking less every month.
1.65M organic visits on 60,150 keywords, but the footprint is bottom-heavy and shed a net 35,000 rankings. We crawled and scored all 474 pages: a clean technical base undercut by a bare homepage with no schema, no canonical, no entity markup — and Reddit owns #1 on 13 of 22 of your money terms.
The verdict — composite & the three pillars
SEO is MODERATE — strong technically, hollow on-page, sliding in the rankings.
A clean technical base and genuinely strong off-page authority (123,340 referring domains), undercut by a bare homepage with no schema, no canonical, no entity markup. Across all 474 crawled pages, not one reaches STRONG. The bullets below mark each pillar's target — the gap is the work.

Ranks only for its own brand and inventions. Reddit owns #1 on 13 of 22 targets — none defended by a strong page.
Competitive — anthropic.com vs openai.com
The gap, metric by metric
Anthropic sits #4 of 7 AI labs by organic traffic — and your closest rival turns the same category into 22× the organic traffic, 21,209 top-3 rankings to your 3,430. Same product tier, a sliver of the search real estate. Competitive Gap tool →
Content signals
The link mismatch — deep pages, starved of links
Off-page authority
Authority Score 69 — healthy, natural, under-converted
A clean, natural backlink profile — no link farms, 81.6% follow, tier-1 media earned (NYT, Guardian, NASA.gov at Authority 91+). The off-page foundation is genuinely strong. The problem isn't authority — it's that this authority isn't translating into rankings, and you still trail OpenAI's 414K referring domains by 3.4×. Reclaim the 23,133 lost-but-vital links, then close the gap. Full Backlinks & Authority →
SEO fixes — impact-ordered, deployable
The lift bridge
The fixes, in priority order
Organization + Person + sameAs schema
+10463 of 474 pages carry zero JSON-LD. Define the entity with sameAs to Wikipedia / Crunchbase / LinkedIn / GitHub — template-level, so it ships site-wide.
Rewrite the homepage title
+5"Home \ Anthropic" (16 chars, no keyword) → a descriptive, keyword-led title.
Add self-referential canonicals
+3Only 8% of pages declare a canonical — add <link rel=canonical> in the template.
Freshness dates site-wide + de-dup metas
+40% of pages dated. Add datePublished + dateModified; write unique metas.
Add H1 to the pages missing one
+2/claude-corps & /engineering forfeit their strongest on-page signal.
Fix the 87 slow pages (TTFB > 4s)
+2Worst is 9.98s. Slow TTFB throttles crawl budget across the long tail.
