Understanding Your SEO Score & Issue Severity

View your overall SEO score

When a scan finishes, the Overview shows your overall SEO score as a large dial in the center, with the score out of 100 inside it. The dial color reflects your page health: green for good, orange for needs-improvement, red for critical. Beneath the dial, the Critical error, Recommended, and Improved cards count how many categories fall into each band, and the right-hand list shows every category as a colored bar with its score, sorted weakest first so your biggest problems are at the top.

How the overall score is calculated

The overall number is a weighted average of the category scores, not a plain average. Each category score (0 to 100) is multiplied by its weight, the results are summed, and the total is divided by the sum of the weights, then rounded. Because the weights differ a lot, the same 10-point gain is worth far more in a heavy category than a light one. Here are the exact weights DefiniteSEO uses:

• Keyword Factor (weight 22): How well the page targets its keyword across the title, headings, URL, and body. Tied for the single heaviest category, so keyword relevance has the biggest pull on your overall score.
• Content Factor (weight 22): Depth and quality of your copy: length, paragraphs, readability balance, and structure. Tied with Keyword Factor as the heaviest category.
• Image SEO (weight 14): Alt text, title attributes, image schema, filenames, and aspect ratio. The third-heaviest category, so image fixes often move the score noticeably.
• Common SEO (weight 8): Core on-page tags such as the title, meta description, canonical, and structured data.

Why AI Visibility is scored separately

On the Overview you will see an AI Visibility Score card labeled Separate from your SEO score. It uses the same 0 to 100 scale and the same green, orange, and red colors, but it is deliberately left out of the weighted overall score because it measures AI-search citation eligibility, not classic ranking factors. It is shown on its own card and never feeds the Critical / Recommended / Improved counts. Agentic Browsing, by contrast, is a normal weighted category and does count toward your overall score.

• AI Visibility (excluded): Measures how likely AI assistants and answer engines are to cite your page. Reported on its own card with its own color, with zero weight in the overall score.
• Agentic Browsing (included): Measures how well AI agents can navigate and act on your page. It carries a weight of 3 and is part of the overall score and the bucket counts.

How severity is color-coded

In the sidebar, click any category, such as Common SEO, to see check-level severity. Each check has a colored dot using the same scale as the scores: a green dot means the check is passing, an orange dot is a recommendation worth addressing, and a red dot is a critical issue to fix first. The category dial at the top of the list shows that category’s own score and color, and the small Critical error, Recommended, and Improved tallies count the checks inside it. The text beside each check explains what was found and what good looks like.

• Meta Title: Checks your page has a title tag of a good length (about 51-60 characters). It is what users see in search results and strongly affects clicks.
• Meta Description: Checks for a clear page summary (about 105-160 characters), which forms the snippet shown under your title in search results.
• BreadCrumb: Looks for breadcrumb navigation, which helps visitors and search engines understand where a page sits in your site.
• SEO Friendly URL: Checks the URL is clean and descriptive, so it is easy for search engines and people to read.

How the Critical, Recommended, and Improved counts work

The three cards on the Overview, and the matching tallies on each category, simply group scores by the same thresholds as the colors. A category or check is Critical when its score is 30 or below, Recommended when it is above 30 and up to 70, and Improved when it is above 70. Categories that do not apply (for example Video SEO on a page with no video) show as N/A and are left out of every bucket, so the counts always reflect only what was actually measured.

• Critical error (red, score 30 or below): The weakest categories or checks. These drag your overall score down the most and should be your first priority.
• Recommended (orange, score above 30 up to 70): Working but with clear room to improve. Address these after the critical items to push the score higher.
• Improved (green, score above 70): Already in good shape. Keep an eye on them after future changes, but they need no immediate work.

Fix critical issues first

Use the sidebar score chips to find your lowest-scoring categories, such as Images, then work through their critical (red) checks before the orange recommendations. Because the overall score is weighted, clearing critical issues in a heavy, low-scoring category, such as Keyword Factor, Content Factor, or Image SEO, raises your overall score the fastest. A red dot in a heavy category is the single highest-leverage thing you can fix.

• Alt Attribute: Checks every image has alt text, which aids accessibility and tells engines what the image shows.
• Title Attribute: Checks images have title attributes that add context on hover.
• Image Schema: Looks for structured data on images so engines can better understand and surface them.
• Image Filename: Checks images use descriptive file names instead of generic ones like IMG_1234.
• Aspect Ratio: Checks images keep correct proportions, which improves layout stability and visual quality.
