SEO Score Calculator

Step-by-Step Guide

1. 1Enter the page details: Type the page title, meta description, target keyword and URL slug. Together these four fields are worth 40 of the 100 points.
2. 2Add the content figures: Enter the word count, the H1 text, the number of images and how many have ALT text, and the internal and external link counts, from your CMS or the published page.
3. 3Set the technical checks: Tick HTTPS, mobile-friendly and canonical tag if they apply, and set the robots meta tag to index unless the page should stay out of search.
4. 4Read the score: The score from 0 to 100, a grade from F to A+ and a list of fixes, highest-value first, update as you type. Load the sample to see a worked example.
5. 5Copy the report: Copy the report to paste into an audit document or ticket, and compare it after your changes.

Pro Tips

• 💡Always put your primary keyword at the very start of your title tag, not the end. Google weights the beginning of titles more heavily, and users scanning SERPs read left to right.
• 💡A meta description doesn't directly affect rankings, but a well-written one at 150–160 characters with a clear benefit and call to action can improve click-through rate by 15–30% — which is a strong indirect ranking signal.
• 💡Content length matters, but depth matters more. A 2,000-word page that answers the reader's full question will outrank a 1,500-word page that doesn't. Use the word count as a minimum threshold, not the goal.
• 💡If your keyword density is above 2.5%, reduce it by replacing some instances with synonyms and semantic variants. Google's natural language processing understands related terms, and keyword stuffing is a downgrade signal.
• 💡Internal linking is the most underrated factor on this checklist. Three or more contextual internal links to related pages distributes link equity across your site and helps Google understand your content structure. Add them in the body copy, not just a 'related posts' sidebar.
• 💡Always add a canonical tag even if you have no known duplicate content problem. It pre-emptively prevents duplication from URL parameters, tracking tags, and CDN variants — and it's a 3-point quick win in the score.

Common Mistakes to Avoid

• ✕Don't chase a perfect score of 100 at the expense of readability. A title forced to exactly 60 characters with a keyword crammed in often sounds unnatural. Humans click it first — Google sees the click-through rate second.
• ✕Don't use the same title tag on multiple pages. Duplicate titles fragment ranking signals and confuse search engines about which page should rank for the query.
• ✕Don't skip ALT text on decorative images just because they don't seem important. Even generic ALT like 'SEO audit dashboard screenshot' helps accessibility and adds a minor relevance signal.
• ✕Don't ignore the robots meta flag. A forgotten noindex tag — left over from staging — is one of the most common reasons a well-optimised page never appears in search results.
• ✕Don't treat this score as a guarantee of ranking. On-page optimisation is one of three pillars (alongside backlinks and technical performance). A score of 95 on a new domain with no backlinks will still rank below a score of 70 on an established DA-50 site for competitive keywords.
