UpStart SEO Tools

The Most Comprehensive SEO Analysis Tool for Founders

Most SEO checkers grade a single page against a handful of rules. Ours crawls your entire site, maps how every page connects, and runs more than 100 automated checks — then tells you exactly what to fix, on which page, and how many points each fix is worth.

SEO is where most startups quietly leak growth. A missing canonical tag, a page no internal link points to, content your framework renders only in the browser — none of it throws an error, and all of it costs you rankings for months. The problem is that most free SEO tools only look at one page and check the obvious things, so the issues that actually move rankings never surface.

We built the analysis to be genuinely thorough. You paste a URL, and it does the work a technical SEO consultant would — across your whole site, not just the homepage.

It analyzes your whole site, not one page

The crawler starts at your homepage and follows your internal links and XML sitemap the same way Googlebot does, building a complete map of your site. That's what makes it possible to catch the site-wide problems single-page tools are blind to:

  • Duplicate titles and meta descriptions repeated across dozens of pages.
  • Canonical tags that quietly point search engines away from the pages you want ranked.
  • Trailing-slash, case, and query-parameter variants that split your ranking signals across duplicate URLs.
  • Sitemap entries that 404, redirect, or contradict your canonicals.

It maps your internal link graph

Internal linking is one of the strongest ranking levers you control, and almost nobody audits it properly. We build an interactive graph of your entire site, compute PageRank across it, and surface the structural problems that bleed rankings:

  • Orphan pages — pages nothing links to, so search engines barely crawl them.
  • Dead zones — pages in your sitemap that no path of internal links reaches from your homepage.
  • Weak-link zones — real pages starved of internal link equity, ranking far below their potential.
  • Dead ends — pages with no outgoing links that trap crawlers and visitors.

You can zoom, pan, and hover any node to see exactly how it's connected. Fixing these is often the single highest-impact thing a site can do — and it's invisible without a full-site graph.

More than 100 checks across every layer of SEO

The rule engine runs on every crawled page and across the site as a whole. A sample of what it covers:

  • Indexing & crawlability: canonicals, robots.txt, XML sitemaps, www and HTTPS redirects, accidental noindex traps, soft 404s.
  • Metadata: title and description quality, length targets, and cross-page uniqueness.
  • Content & headings: H1 presence, heading hierarchy, thin content, placeholder text left in production, even likely misspellings.
  • Structured data: JSON-LD validity plus Organization, BreadcrumbList, FAQ, and ItemList schema.
  • International: hreflang validity, reciprocity, and x-default coverage.
  • Images: alt text, explicit dimensions, lazy loading, modern formats, and image sitemaps.
  • Rendering: detects content that only appears after JavaScript runs — the kind search engines may never see.
  • Internal linking, performance, accessibility, AI-search readiness, and trust signals.

Every issue is scored and prioritized

A long list of problems is only useful if you know what to fix first. Every audit gives you a single overall score out of 100, and every finding is graded critical, warning, or recommendation — grouped by type and tied to the exact page and URL it affects.

Each finding also carries a green +N points stamp showing how much your score recovers when you fix it. So instead of guessing, you work top-down through the changes that move rankings the most, and watch the number climb as you go.

It looks beyond your site, too

Your own HTML is only half the story. The analysis also checks whether Google and Brave actually index your domain — because a technically perfect site that isn't in the index ranks for nothing. And it pulls your real Core Web Vitals (LCP, CLS, INP) and Lighthouse performance from Google's field data, flagging the ones in the "poor" range that drag down both rankings and conversions.

Built to move rankings, not to look busy

Every finding is written in plain language with a concrete fix, never a vanity metric with no next step. The full report lives at a shareable link, so you can hand it to a developer or teammate and they see exactly what you saw. Run it before a launch, after a redesign, or on a schedule — each pass is a fresh, structured snapshot of where your SEO stands.
