seo.co
Link authority for seo.co (registrable domain: seo.co) from the Common Crawl web graph: PageRank and harmonic centrality history since 2017, current scores, and the site's top backlink sources.
Web-graph authority (0-100)
Domain scores measure seo.co as a whole: every subdomain's links rolled up into one node of Common Crawl's domain-level web graph. Host scores measure the exact hostname seo.co. WWW scores cover the www variant of that hostname, which the graph tracks as its own entry since January 2026 (before that, www and bare host were merged). A big gap between domain and host usually means the domain's authority lives on other subdomains. PageRank is link-endorsement authority: how much weight the sites linking here carry themselves. Harmonic centrality measures reach: how close this site sits to the rest of the web when following links, which favors broadly connected sites over ones boosted by a few heavy linkers. All are normalized 0 to 100 within each crawl snapshot; a dash means that series does not exist for this site.

{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What does an SEO company actually do?","acceptedAnswer":{"@type":"Answer","text":"A full-service SEO company improves how a website ranks in organic search and how it's cited by AI answer engines. At SEO.co that means three connected disciplines: technical SEO (making the site fast, crawlable, and machine-readable), on-page content and keyword strategy (matching real search intent), and off-page authority through editorial link building and digital PR. We tie all of it to organic traffic and revenue rather than vanity metrics."}},{"@type":"Question","name":"What's the difference between an SEO company and an SEO agency?","acceptedAnswer":{"@type":"Answer","text":"In practice the terms are interchangeable — both describe a team you hire to grow organic search visibility. \"SEO agency\" tends to imply a broader marketing relationship, while \"SEO company\" often signals a specialist focused purely on search. SEO.co is both: a specialist SEO company with the full-service depth of an agency, including technical SEO, content, link building, local SEO, and AI search optimization."}},{"@type":"Question","name":"How much does it cost to hire an SEO agency?","acceptedAnswer":{"@type":"Answer","text":"Most credible SEO agencies in the US price retainers between roughly $2,500 and $15,000+ per month depending on scope, competition, and the size of your site. Enterprise programs and aggressive link-building campaigns run higher. SEO.co scopes engagements to your goals and gives you a clear breakdown of strategy, content, technical work, and authority building so you know exactly what each dollar buys."}},{"@type":"Question","name":"How long does SEO take to show results?","acceptedAnswer":{"@type":"Answer","text":"Most clients see early movement in 3–4 months and meaningful organic growth in 6–12 months. Technical fixes and existing-page optimization can move rankings within weeks; new content and link authority compound over quarters. Timelines depend on domain authority, competition, and how much technical debt the site is carrying — we forecast all of this in the initial audit."}},{"@type":"Question","name":"What makes SEO.co different from other SEO companies?","acceptedAnswer":{"@type":"Answer","text":"Three things. We approach SEO with engineering discipline — audits, hypotheses, and instrumented rollouts rather than a content treadmill. We build AI search optimization (GEO/AEO) into every engagement instead of selling it as an add-on. And we only build real, editorial authority — no PBNs, link farms, or shortcuts that get clawed back at the next core update."}},{"@type":"Question","name":"Do you optimize for AI search like ChatGPT and Google AI Overviews?","acceptedAnswer":{"@type":"Answer","text":"Yes — it's built into every engagement. Generative engine optimization (GEO) and answer engine optimization (AEO) make your brand recognizable as a real-world entity in knowledge graphs, structure your content to be retrieved and quoted, and monitor which prompts cite you across ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews."}},{"@type":"Question","name":"What's included in technical SEO?","acceptedAnswer":{"@type":"Answer","text":"Crawlability and indexation control (log-file analysis, robots.txt, XML sitemaps, canonicalization), Core Web Vitals and page-speed optimization, information architecture and internal linking, JavaScript-rendering audits, and Schema.org structured data that powers both rich results and AI citations."}},{"@type":"Question","name":"Do you offer local SEO and multi-location SEO?","acceptedAnswer":{"@type":"Answer","text":"Yes. We optimize and manage Google Business Profiles, build local citations with consistent NAP data, run review-acquisition programs, and handle multi-location and franchise local SEO at scale. Every local landing page is built bespoke for its market — we never ship name-swapped templates."}},{"@type":"Question","name":"What kind of link building do you do?","acceptedAnswer":{"@type":"Answer","text":"White-hat, editorially placed links and digital PR from publications people actually read. We earn coverage and brand mentions, manage anchor-text strategy and link velocity so placements survive core updates, and run backlink audits with disavow management to clean up toxic legacy profiles. No PBNs, link farms, or paid link schemes."}},{"@type":"Question","name":"Can you handle enterprise and ecommerce SEO?","acceptedAnswer":{"@type":"Answer","text":"Yes. For enterprise we provide templated optimization that scales across millions of URLs, SEO governance and workflow, and migration planning so replatforms don't cost you rankings. For ecommerce we optimize category, product, and faceted navigation across Shopify, Magento, BigCommerce, and WooCommerce, including product schema and Google Shopping visibility."}},{"@type":"Question","name":"Which industries does SEO.co work with?","acceptedAnswer":{"@type":"Answer","text":"We work across SaaS and technology, healthcare, finance and fintech, legal, ecommerce and retail, real estate, B2B and manufacturing, education, and travel and hospitality — from venture-backed startups to Fortune 500 enterprises. Our process adapts to regulated industries and competitive SERPs alike."}},{"@type":"Question","name":"How do you report on SEO performance?","acceptedAnswer":{"@type":"Answer","text":"Transparent, revenue-oriented reporting. You get dashboards built on GA4 and Google Search Console, plus visibility tracking in tools like Ahrefs and Semrush. We report on organic traffic, keyword rankings, conversions, and AI-citation share — and we tell you plainly what worked, what didn't, and what's next."}},{"@type":"Question","name":"Do you require long-term contracts?","acceptedAnswer":{"@type":"Answer","text":"SEO is a compounding investment, so we recommend a runway of at least six months to see meaningful results — but we earn renewals with performance, not lock-in. We're happy to scope a defined initial engagement (such as an audit and 90-day roadmap) before you commit to an ongoing program."}},{"@type":"Question","name":"Is SEO still worth it with AI answer engines changing search?","acceptedAnswer":{"@type":"Answer","text":"More than ever — the surfaces just multiplied. The same fundamentals that earn Google rankings (authority, relevance, structured content, technical health) are what get you cited in ChatGPT, Perplexity, and AI Overviews. A modern SEO company optimizes for all of them at once, which is exactly how we built SEO.co."}}]}Authority over time
Every Common Crawl web-graph release since 2017, roughly quarterly. The domain series goes back to 2017; Common Crawl only began publishing the host-level graph in 2020, so host lines start there. Click a legend entry to show or hide that line. Flat lines are normal for established sites; watch for sustained rises or drops, which track real gains or losses in who links here.
A note on www: through the end of 2025 the source web graph merged www and non-www hostnames into the bare name, so one host line covers both. Starting in January 2026 the graph splits them into separate entries, which is why www can carry its own scores going forward.
Backlink counts
Unique linking domains seen in Common Crawl's link graphs. This is a different dataset than the 0-100 authority scores above: these are raw counts, host-level for seo.co and domain-level for seo.co with all its subdomains combined. Common Crawl covers a large sample of the web, not all of it, so treat counts as comparable between sites rather than absolute totals.
Top backlinks in the domain graph
Common Crawl publishes two link graphs. The DOMAIN graph connects whole domains: every link from any page of one domain to any page of another. This table shows the highest-authority domains linking to seo.co (including its subdomains), ranked by the linker's PageRank. The table shows the top 752; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
Top backlinks in the host graph
The HOST graph connects exact hostnames, so subdomains count separately. This table shows the highest-authority hosts linking to seo.co specifically, ranked by the linker's PageRank. The table shows the top 771; the download carries the full stored list (up to 10,000 linkers) as JSON. Click a linker for its own site profile.
