On-Page SEO Audit Report: What to Check on Every Page

Aug 05, 2026 · SEO Audits

On-page SEO is what you control directly: the title tag, meta description, heading structure, content quality, image alt text, and internal links on each page. An on-page SEO audit report systematically checks these elements across your site and identifies what's missing, broken, or suboptimal.

On-Page SEO Audit Checklist

Use this checklist for every page you audit. A crawler like WebsiteChecker.Tech automates most of these checks across all pages at once.

Title Tags

Meta Descriptions

• Present: Every page should have a meta description. Google will auto-generate one if missing, and it's usually bad.
• Length: 140-160 characters. Longer gets truncated.
• Unique: No duplicates across pages.
• Actionable: Include a reason to click — a benefit, a number, or a question answered.

Heading Structure (H1-H6)

• One H1 per page — contains the primary keyword, describes the page topic
• Logical hierarchy — H2s under H1, H3s under H2s. Don't skip levels (H1 → H3).
• Descriptive headings — "Our Services" is weak. "WordPress Maintenance Plans for Small Businesses" is strong.
• No missing H1 — common on homepages that use the logo as the only "heading"

Content Quality

Images

• Alt text: Every image should have descriptive alt text. Not "image1.jpg" — describe what the image shows.
• File size: Images over 200KB should be compressed. Use WebP format where supported.
• Dimensions: Don't serve a 3000px image in a 600px container. Resize to display dimensions.
• Lazy loading: Images below the fold should use lazy loading to improve initial page speed.

Internal Links

• Orphan pages: Every important page should be linked from at least one other page on your site.
• Broken links: Internal links pointing to 404 pages waste crawl budget and frustrate users.
• Anchor text: Use descriptive anchor text, not "click here." The anchor text tells Google what the linked page is about.
• Link depth: Key pages should be reachable within 3 clicks from the homepage.

URL Structure

• Short and descriptive: `/services/wordpress-maintenance/` not `/page?id=4837&cat=2`
• Lowercase: URLs should be lowercase. Mixed case can cause duplicate content issues.
• No underscores: Use hyphens to separate words. Google treats hyphens as word separators, underscores as joiners.
• Consistent trailing slashes: Pick one format and redirect the other.

Presenting On-Page Findings to Clients

Group findings by impact, not by check type. Clients don't care about "meta descriptions" as a category — they care about "things that affect how you appear in search results."

Effective grouping:

1. Search appearance issues — title tags, meta descriptions (affects click-through rate)
2. Content issues — thin pages, duplicate content, missing keywords (affects rankings)
3. Navigation issues — broken links, orphan pages, poor link depth (affects user experience and crawlability)
4. Image issues — missing alt text, oversized images (affects accessibility and speed)

For each finding, include the specific pages affected and the recommended fix. A finding without an action step is just noise.

Automating On-Page SEO Audits

Checking title tags, meta descriptions, headings, and image alt text manually across 100+ pages is tedious and error-prone. Use a crawler to do the bulk checking.

WebsiteChecker.Tech crawls every page on a site and flags on-page issues automatically — missing titles, duplicate descriptions, pages without H1 tags, images missing alt text, broken internal links, and more. The report explains each issue in plain English and prioritizes by severity, so you can hand it directly to a client or developer.
