How the SEO Score Is Calculated
This calculator evaluates 10 on-page and technical SEO factors, each weighted by its impact on search rankings. The total is a 0-100 scale — higher is better. Every factor is scored independently, so you can see exactly where points are lost and what to fix first.
The scoring breaks down into two groups: On-Page SEO (55 points) covers title, description, H1, and content length. Technical (45 points) covers page speed, image alt text, internal links, canonical URLs, mobile-friendliness, and HTTPS.
Title Tag Optimization
Your title tag is the single most important on-page SEO element. It appears as the clickable headline in search results and directly influences both rankings and click-through rates.
Scoring (15 points):
- 50-60 characters — full 15 points. This is the sweet spot where your title displays completely in Google without truncation.
- 30-70 characters — 10 points. Functional but not optimal. Titles under 50 miss ranking opportunities; over 60 risk truncation.
- Outside 30-70 — 0 points. Titles this short lack keyword context, and titles this long will be cut off or rewritten by Google.
Keep your primary keyword near the beginning of the title. Google gives more weight to early words, and truncated titles still show the start.
Meta Description Optimization
The meta description doesn't directly affect rankings, but it heavily influences click-through rate — which indirectly affects rankings. A compelling description can double your CTR compared to a generic one.
Scoring (15 points):
- 120-160 characters — full 15 points. Long enough to be persuasive, short enough to display completely.
- 70-200 characters — 10 points. Workable but either too brief to convince or too long for full display.
- Outside 70-200 — 0 points. Too short to be useful, or so long that Google ignores it entirely.
Include your target keyword naturally — Google bolds matching terms in the description, which catches the searcher's eye.
Content Length and Quality
Word count alone doesn't determine rankings, but thin content rarely ranks well. Longer content gives search engines more context and typically covers topics more thoroughly.
Scoring (15 points):
- 1,000+ words — full 15 points.
- 300-999 words — sliding scale. The score increases proportionally as you approach 1,000 words.
- Under 300 words — 0 points. Pages this thin are unlikely to rank for competitive queries.
Focus on comprehensive, useful content rather than padding word count. A 600-word page that fully answers the searcher's question is better than a 1,500-word page that rambles.
Page Speed Impact
Page speed is a confirmed Google ranking factor and a Core Web Vital. Slow pages lose visitors — 53% of mobile users abandon pages that take over 3 seconds to load.
Scoring (15 points):
- Under 2 seconds — full 15 points. This is the target for optimal user experience and SEO.
- 2-3 seconds — 10 points. Acceptable but leaves room for improvement.
- 3-5 seconds — 5 points. Users are dropping off, and rankings are likely affected.
- Over 5 seconds — 0 points. Critical speed issue.
Common speed fixes: compress images (WebP format), enable browser caching, minimize render-blocking JavaScript, and use a CDN.
Image Alt Text
Alt text helps search engines understand image content and is essential for accessibility. Pages with complete alt text coverage rank better in both standard and image search.
Scoring (10 points):
The score is proportional — if 75% of your images have alt text, you earn 7.5 out of 10 points (rounded). Pages with no images automatically receive full points since there's nothing to optimize.
Write alt text that describes the image content naturally. Avoid keyword stuffing — "red leather wallet side view" is better than "best leather wallet buy leather wallet cheap."
Internal Linking
Internal links help search engines discover and understand the relationship between your pages. They also distribute page authority (link equity) throughout your site.
Scoring (5 points):
- 3+ internal links — full 5 points.
- 1-2 internal links — 3 points.
- 0 internal links — 0 points. Orphan pages are harder for search engines to find and rank.
Link to your most important pages using descriptive anchor text. "See our leather wallet collection" is better than "click here."
Technical Basics
Three binary checks round out the score:
Canonical URL (5 points): A canonical tag tells search engines which version of a page is the "official" one. Without it, duplicate content can dilute your rankings — especially on e-commerce sites with filtered views, pagination, or tracking parameters.
Mobile-Friendly (5 points): Google uses mobile-first indexing, meaning it primarily uses the mobile version of your page for ranking. If your page isn't responsive, you're leaving rankings on the table.
HTTPS (5 points): HTTPS is a lightweight ranking signal. More importantly, browsers flag HTTP pages as "Not Secure," which tanks user trust and conversion rates. There's no reason not to use HTTPS in 2025.
