SEO Score Checker

Most SEO audits overwhelm you with a list of 200 issues ranked by severity, leaving you no clearer on where to start. This tool does the opposite — it checks 30+ signals across six categories, then ranks the output by expected impact relative to implementation effort. Fix the first three things on the list and you will have done more than most sites ever do.

The Six Audit Categories

1. Core Web Vitals

Google uses Core Web Vitals as a direct search ranking input. The tool checks your LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and INP (Interaction to Next Paint) against the Google thresholds of Good / Needs Improvement / Poor. A site scoring Poor on any of these is being penalised in search results every day it remains unresolved.

2. On-Page Fundamentals

Title tags, meta descriptions, H1s, heading hierarchy, and image alt text — the foundational signals that search engines use to understand what every page is about. These are the highest-impact, lowest-effort fixes in any SEO audit. Missing or duplicate title tags alone can suppress ranking across an entire site.

3. Technical SEO

robots.txt configuration, XML sitemap presence and validity, canonical tags, redirect chain length, HTTPS enforcement, and crawlability signals. Technical issues in this category can prevent pages from being indexed at all — making every other SEO investment worthless until they are resolved.

4. Structured Data

JSON-LD schema markup for Organisation, WebSite, BreadcrumbList, Article, Product, and FAQPage where applicable. Structured data does not directly affect ranking but enables rich results (star ratings, FAQ dropdowns, sitelinks) that increase click-through rate significantly for qualified queries.

5. Mobile Optimisation

Google indexes the mobile version of your site first. The tool checks viewport meta tag, touch target sizes, font sizes on mobile, and content width relative to viewport. Mobile issues that go unnoticed on desktop audits are among the most common sources of ranking suppression for sites with otherwise good SEO.

6. Social and OG Tags

Open Graph and Twitter Card tags determine how your pages look when shared on social media. While not a direct ranking factor, missing OG tags suppress click-through rates from social distribution which indirectly affects the engagement signals Google uses as quality indicators.

How the Prioritised Output Works

Each finding is scored on two axes: Expected Impact (how much fixing this is likely to improve organic performance) and Implementation Effort (how long it typically takes to resolve). The output is sorted by the ratio of impact to effort — so the fixes at the top of your list are the ones that give you the most return for the least work.

• P1 — High impact, low effort: title tag and meta description fixes, missing alt text, robots.txt corrections. Fix these first, always
• P2 — High impact, medium effort: Core Web Vitals improvements, canonical tag corrections, structured data additions
• P3 — Medium impact, low effort: OG tags, heading hierarchy corrections, mobile viewport adjustments
• P4 — Medium impact, medium effort: redirect chain consolidation, sitemap submission, schema markup expansion
• P5 — Lower impact items: these are documented but deprioritised — address them after P1–P4 are clear

“The prioritisation is what makes this tool useful rather than just comprehensive. I ran a manual audit with a well-known SEO crawler and got 340 issues. Ran this tool, got 18 prioritised findings. Fixed the top 5 in an afternoon. Organic traffic was up 28% within 6 weeks.”
