What does an on-page SEO audit check?

An on-page audit analyzes a single URL for technical SEO factors: title tag length and keyword usage, heading hierarchy (H1–H6), image alt text completeness, canonical tag configuration, meta robots directives, internal and external link counts, and Open Graph tag presence.

How often should I audit my pages?

Audit key pages (homepage, pricing, landing pages) monthly or after any major content update. For startups iterating quickly, run audits before and after redesigns or content rewrites to catch regressions in SEO fundamentals.

Why is heading hierarchy important for SEO?

Search engines use headings to understand page structure and content hierarchy. Every page should have exactly one H1 (main topic), followed by H2s for sections, H3s for subsections, and so on. Skipping levels (e.g., H1 → H3) signals poor content structure and can hurt rankings.

Why On-Page SEO Audits Are Essential for Startup Growth

On-page SEO is the foundation upon which all other search optimization efforts are built. You can invest heavily in link building, content marketing, and social promotion, but if your pages have fundamental technical issues — a missing title tag, broken heading hierarchy, or images without alt text — search engines will struggle to properly index and rank your content. An on-page SEO audit systematically checks every page-level factor that influences how search engines understand and evaluate your content.

For startups iterating quickly, on-page SEO regressions happen constantly. A redesign might remove the canonical tag. A developer might nest headings incorrectly. A content update might introduce images without alt text. Regular audits catch these issues before they compound into ranking drops.

What This Tool Checks

Title Tag Analysis — Verifies your title exists, checks its length against Google's ~600 pixel display limit, identifies keyword presence, and flags common issues like duplicate or generic titles ("Home" or "Untitled").

Heading Hierarchy (H1–H6) — Ensures exactly one H1 per page, validates proper nesting (no skipping from H1 to H3), and flags pages with missing or multiple H1 tags. Proper heading structure helps search engines understand your content's topic hierarchy.

Image Alt Text Completeness — Scans every image on the page and reports which ones lack alt text. Alt text is crucial for accessibility and image search visibility. It also serves as fallback content when images fail to load.

Canonical Tag Configuration — Checks for the presence and correctness of the canonical URL tag. A missing or incorrect canonical can cause duplicate content issues that dilute your ranking potential across multiple URL variants.

Internal Link Health — Counts internal and external links, identifies links pointing to error pages, and checks for orphaned pages that lack internal links pointing to them.

Meta Robots & Open Graph — Verifies that your robots meta tag isn't accidentally blocking indexing, and checks that Open Graph tags are properly configured for social sharing.
