Before publishing any page, keep a checklist of 15 items. This list separates a page getting 100 monthly visits from one getting 10,000. SEO audit isn't optional — it's a necessity for every page you publish.
Why Regular Audits Matter
SEO isn't a one-time process. Google's algorithms update 4,000+ times yearly. Each update may change your page rankings. A page that was #3 last year might be #20 today. Regular audits catch these drops before they hurt you.
Also: every new page must pass an SEO audit before publishing. This saves you from indexing errors that are hard to fix later.
Essential On-Page Checks
1. Title Tag — exists, unique, 50-65 chars, contains keyword.
2. Meta Description — exists, 130-160 chars, motivates clicking.
3. H1 — exists, only one per page, describes content.
4. Heading structure — H2, H3 organized logically. No H4 without an H3 before it.
5. Image ALT — every image has a useful text description.
6. Internal links — every page links to 3-5 other relevant pages.
Technical Checks
7. HTTPS — your site uses SSL. A baseline since 2014.
8. Mobile-Friendly — works on mobile without issues. Test with Google's tool.
9. Canonical Tag — present and points to the correct version.
10. Robots Meta — correct. index,follow for public pages.
11. Load speed — TTFB under 800ms. LCP under 2.5 seconds.
Social Checks
12. Open Graph — og:title, og:description, og:image (1200×630) all present.
13. Twitter Cards — twitter:card set to summary_large_image.
Structured Data Checks
14. JSON-LD Schema — appropriate Schema type for the page exists and is valid.
15. Sitemap — the page exists in sitemap.xml.
How Is a 0-100 Score Calculated?
Every SEO audit tool has its formula. General rule:
Start at 100.
Critical issue: -10 to -15 points. Like a missing Title.
Warning: -3 to -7 points. Like an overly short Title.
Info: -1 to -2 points. Like missing lang attribute.
Quality bands:
90+: Excellent. 75-89: Good. 50-74: Fair. 30-49: Poor. Below 30: Critical.
Examples of Critical Issues
1. Empty Title. Google uses your site name as title. Devastating for SEO.
2. Accidental noindex. Entire pages removed from Google. Often happens when moving site from staging to production.
3. Canonical pointing to wrong page. Google indexes the wrong version.
4. No HTTPS. Chrome shows "Not Secure" and users flee.
On-Page vs. Off-Page Difference
On-Page SEO: Everything inside your page. Title, description, content, images, internal links.
Off-Page SEO: What happens outside your site. Backlinks, social signals, mentions on other sites.
A single-page audit tool focuses on On-Page. Off-Page needs different tools (Ahrefs, Semrush).
When to Audit
Before publishing any new page.
After every major update.
Monthly for core pages (homepage, pricing, contact).
When you notice ranking drops.

2. Add missing elements before optimizing existing. Schema, Open Graph, Canonical. Simple additions with big impact.
3. Update old content. Pages older than a year need refreshing. Add new info, update numbers.
4. Improve site speed. WebP instead of PNG, CDN, caching. Good speed = +10 points.
