Open an audit from the [Audits](/audits/overview) list to see its issues. Each issue names the page it was found on, describes the problem with the specific measurement, and gives a recommendation. ## Severity Three levels, which determine both urgency and the [score](/audits/overview#the-audit-score) impact: | Severity | Deduction | What it means | | ----------- | ------------------- | -------------------------------------------------------- | | **Error** | −2 each, up to 50 | Actively harming crawling, indexing, or users. Fix first | | **Warning** | −0.5 each, up to 30 | Costing you performance but not breaking anything | | **Notice** | −0.1 each, up to 10 | Informational; often intentional | Work errors first. Notices frequently need no action at all — a `noindex` on a thank-you page is correct. ## Meta tags | Issue | Severity | Trigger | Fix | | ------------------------- | -------- | ---------------------------------- | ---------------------------------------------------- | | **Missing title** | Error | No `` | Add a unique title of 50–60 characters | | **Title too long** | Warning | Over 60 characters | Shorten to 50–60 so it isn't truncated in results | | **Title too short** | Warning | Very short | Expand to 50–60, including the primary keyword | | **Duplicate title** | Warning | Same title on multiple pages | Give each page a unique title | | **Missing description** | Error | No meta description | Add one of 120–155 characters | | **Description too long** | Warning | Over 155 characters | Shorten to 120–155 | | **Description too short** | Warning | Very short | Expand to 120–155 | | **Duplicate description** | Warning | Same description on multiple pages | Write a unique one per page | | **Missing H1** | Error | No `<h1>` | Add a single descriptive H1 with the primary keyword | | **Multiple H1** | Warning | More than one `<h1>` | Keep one; demote the rest to `<h2>` | Duplicate title and description issues depend on crawl coverage — both copies must be crawled for the duplication to be detected. A narrow crawl under-reports them. ## Links | Issue | Severity | Trigger | Fix | | ------------------------ | -------- | -------------------------------------- | -------------------------------------------------------------------------------- | | **Broken internal link** | Error | Internal link returns an error status | Fix or remove it | | **Broken external link** | Warning | External link returns an error status | Update, redirect, or remove | | **Redirect chain** | Warning | Multiple hops to reach the destination | Link directly to the final URL | | **Redirect loop** | Error | A page redirects to itself | Fix the server or CMS redirect rules — looping pages are completely inaccessible | | **Orphan page** | Warning | No internal links point to the page | Add at least one internal link from a relevant section | Broken links are reported with the HTTP status they returned, and redirect chains with the number of hops — enough to triage without opening each URL. Orphan pages need a broad crawl to detect reliably: a page can look orphaned simply because the crawl never reached whatever links to it. ## Performance | Issue | Severity | Threshold | Fix | | ------------------------- | -------- | ----------------------------- | ------------------------------------------------------------ | | **Slow page** | Warning | Load time over **3,000 ms** | Compress images, enable caching, reduce server response time | | **Large page** | Warning | Page over **3,072 KB** (3 MB) | Compress images, remove unused CSS and JS | | **Large image** | Notice | Oversized image file | Convert to WebP, aim for under 200 KB per image | | **Uncompressed resource** | Notice | No `Content-Encoding` header | Enable gzip or Brotli on the server | Each issue reports its actual measurement, so you can see how far past the threshold a page is. These are crawl-time measurements from a single request. For field-quality performance data, use [Web vitals](/web-vitals/overview). ## Images | Issue | Severity | Trigger | Fix | | -------------------- | -------- | --------------------------------------------------- | ------------------------------------------------------------------- | | **Missing alt text** | Warning | Images with no alt attribute, reported with a count | Add descriptive alt text — it serves accessibility and image search | | **Broken image** | Error | Image returns an error status | Fix or replace it | ## Indexing | Issue | Severity | Trigger | Fix | | ---------------------- | -------- | ---------------------------- | ------------------------------------------------------------ | | **Noindex page** | Notice | A `noindex` robots directive | Verify it's intended; remove if the page should rank | | **Blocked by robots** | Notice | Disallowed in `robots.txt` | Review the rules — blocked pages can't be indexed | | **Missing canonical** | Warning | No canonical link element | Add a self-referencing canonical | | **Non-indexable page** | Warning | Something prevents indexing | Decide whether the page should rank, then remove the blocker | The two notices are deliberately low severity because they're usually intentional. Read them as a checklist — "did I mean to exclude these?" — rather than as defects. They're also the issues to check first when a page mysteriously won't rank. ## Content | Issue | Severity | Threshold | Fix | | --------------------- | -------- | ----------------------- | ------------------------------------------------------- | | **Thin content** | Warning | Under **300 words** | Expand — thin pages rarely rank and dilute site quality | | **Duplicate content** | Warning | Near-duplicate detected | Consolidate, rewrite, or canonicalize | The 300-word threshold is a blunt rule. A well-targeted product or contact page under 300 words isn't a problem; a category page padded to 400 words still is. ## Security | Issue | Severity | Trigger | Fix | | ----------------- | -------- | --------------------------------- | ------------------------------------------------ | | **Mixed content** | Error | HTTPS page loading HTTP resources | Serve every resource over HTTPS | | **Missing HTTPS** | Error | Page served over HTTP | Install a certificate and redirect HTTP to HTTPS | Both are errors, and HTTPS also carries a **+5 score bonus** — fixing it moves the score twice. ## Schema | Issue | Severity | Trigger | Fix | | ------------------ | -------- | ------------------ | -------------------------- | | **Missing schema** | Notice | No structured data | Add relevant schema markup | A notice, not an error, because schema isn't a ranking factor in itself. It does affect how your result is displayed, which affects clicks. ## Working through a list 1. **Errors first**, largest deduction and real damage. 2. **Sitewide patterns before one-offs.** An issue on every page is one template fix; the score moves far more per unit of work. 3. **Then the +5 bonuses** — HTTPS, `robots.txt`, sitemap. Three quick wins worth 15 points between them. 4. **Re-run the audit.** The score belongs to the crawl that produced it and won't update on its own. 5. **[Compare](/audits/compare) the two crawls** to confirm what actually got fixed.
