# Verify a fix

> Recheck a fix task's URLs in seconds after you deploy. What is rechecked, what it costs, the limits, and what each result means.

Source: https://seofix.ai/help/verify-fix · Category: Fixes · Updated: 2026-10-08

After you deploy a fix, Verify fix re-fetches only the task's affected URLs (up to 200) and runs the same checks again. It costs 1 credit per URL fetched, needs a verified site, and usually finishes in seconds. When every rechecked URL passes, the task is marked `fixed`. In the app: the "Verify fix" button on any task in the Top 3 or on the tasks page. Agents: `verify_fix` (MCP) or `POST /v1/sites/{id}/recheck`.

## Requirements and limits

| Item | Value |
| --- | --- |
| Site | Ownership must be verified (see [Verify site ownership](https://seofix.ai/help/verifying-site-ownership.md)). Otherwise the button reads "Verify ownership to recheck" and the API answers `409 site_not_verified`. |
| URLs per recheck | 1–200. A task with more than 200 affected pages is sampled: the 200 with the most Search Console clicks, then URL order. |
| Cost | 1 credit per URL. Credits for all URLs are reserved up front; you are charged per URL actually fetched and the rest is refunded. |
| Rate | 30 rechecks per hour per team. A recheck refused for insufficient credits does not count. |
| Crawl speed | At most 2 requests per second, or your site's own lower speed setting. |
| Time | At most 120 seconds of fetching. URLs not reached by then are `not_checked`. |
| Task type | Only tasks with `recheckable: true`. See the table below. |

## What a recheck checks

A recheck fetches each URL once, with the same crawler and user agent as a full audit, and does not follow links. It re-evaluates:

- the URL's response: `BROKEN_PAGE`, `SERVER_ERROR`, `FETCH_FAILED`, `PRIVATE_ADDRESS_SKIPPED`, `BLOCKED_BY_FIREWALL`;
- every on-page check of an HTML page (title, meta description, headings, canonical presence, Open Graph, images, mixed content, JavaScript redirects, size, response time, structured data);
- duplicates (`DUPLICATE_CONTENT`, `DUPLICATE_TITLE`, `DUPLICATE_META_DESCRIPTION`): each rechecked page is compared with the other rechecked pages and with the rest of the site's latest full audit (the "duplicate baseline").

It does not re-evaluate anything that depends on the whole site: internal link graph, sitemap, orphan pages, robots.txt, canonical and redirect targets, hreflang, external links, AI and performance samples, and changes between audits. Those tasks show `recheckable: false`; the app shows "Re-verified at the next full audit" instead of the button, and the API answers `422 cannot_verify`. Run a full audit after fixing them.

### Recheckable check codes

| Group | Codes |
| --- | --- |
| Response | `BROKEN_PAGE`, `SERVER_ERROR`, `FETCH_FAILED`, `PRIVATE_ADDRESS_SKIPPED`, `BLOCKED_BY_FIREWALL` |
| Titles and descriptions | `TITLE_MISSING`, `TITLE_TOO_LONG`, `TITLE_TOO_SHORT`, `MULTIPLE_TITLE_TAGS`, `META_DESCRIPTION_MISSING`, `META_DESCRIPTION_TOO_LONG`, `META_DESCRIPTION_TOO_SHORT`, `MULTIPLE_META_DESCRIPTIONS` |
| Content | `H1_MISSING`, `MULTIPLE_H1`, `THIN_CONTENT`, `IMAGES_MISSING_ALT`, `STRUCTURED_DATA_INVALID` |
| Head tags and links | `CANONICAL_MISSING`, `NOINDEX_PAGE`, `OG_TAGS_MISSING`, `OG_TAGS_INCOMPLETE`, `OG_URL_MISMATCH`, `HTTP_LINK_ON_HTTPS`, `MIXED_CONTENT`, `JS_REDIRECT` |
| Performance | `PAGE_TOO_LARGE`, `SLOW_PAGE` |
| Duplicates | `DUPLICATE_CONTENT`, `DUPLICATE_TITLE`, `DUPLICATE_META_DESCRIPTION` |

Every other check code, and every `INDEX_*` Google triage task, is not recheckable. The [issue reference](https://seofix.ai/help/issue-reference.md) marks each code.

## Results

### Per task

| `result` | Meaning | Task status after |
| --- | --- | --- |
| `fixed` | Every rechecked URL was checked and none has the issue. | `fixed` |
| `still_failing` | At least one URL still has the issue. | `open` |
| `not_checked` | Nothing failed, but some URL could not be checked. | `open` |
| `cannot_verify` | A recheck can't judge this code, or a duplicate check had no baseline (the latest full audit's data was unavailable). | `open` |

Each task result also has `urls_failing`, `urls_passing`, `urls_rechecked`, `pages`, `sampled` and `covers_task`. A `fixed` result records a fix event, which [Traffic from fixes](https://seofix.ai/help/traffic-from-fixes.md) measures.

### Per URL

| `result` | Meaning | App label |
| --- | --- | --- |
| `fixed` | The task's issue is gone. | Fixed |
| `still_failing` | The task's issue is still there. | Still failing |
| `new_issue` | The task's issue is gone, but errors or warnings appeared that the latest audit did not have on this URL (listed in `new_issues`). The task still counts as passing on this URL. | New issue |
| `not_checked` | The URL could not be judged; see `reason`. | Not checked |
| `cannot_verify` | The URL's only task codes are ones a recheck can't verify. | Needs a full audit |
| `passing` | A URL you passed that has no task on it, and no errors. | Passing |

`not_checked` reasons:

| `reason` | Meaning |
| --- | --- |
| `not_fetched` | Not reached (for example the 120-second limit). |
| `blocked` | A firewall or bot challenge answered instead of your page. |
| `fetch_error` | The request failed (DNS, TLS, timeout). |
| `status_<code>` | The URL answered that status, e.g. `status_503`, or `status_404` for an on-page check, which only runs on a 200 HTML answer. |
| `not_html` | The URL answered 200 but not `text/html`, so on-page checks did not run. |

A URL that now answers a 3xx redirect passes its on-page checks and is reported with `redirected: true` and `redirect_to`.

In the app the result line reads "N of M pages pass", with a heading of "Fixed", "Still failing", "Couldn't check every page", "Re-verified at the next full audit" or "The recheck didn't finish". "Verify again" starts a new recheck.

## Rechecking your own list of URLs

Instead of a task, you can pass 1–200 URLs. Each must be an http(s) URL on the site's host (with or without `www`), or the API answers `422 invalid_urls`. SEOFix finds the tasks those URLs belong to in the latest full audit. A task's status changes only when your list covers every one of its affected pages; otherwise you get per-URL results without changing task status.

## For agents

```bash
curl -s -X POST "https://api.seofix.ai/v1/sites/42/recheck" \
  -H "Authorization: Bearer $SEOFIX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"task_key": "3f9c2a71b0d4e8a6"}'
```

Send either `task_key` (16 hex characters) or `urls` (an array of 1–200 strings), not both. The answer is `202`:

```json
{
  "recheck_id": 9188,
  "status": "queued",
  "urls_total": 200,
  "estimated_credits": 200,
  "sampled": true,
  "tasks": [
    {"task_key": "3f9c2a71b0d4e8a6", "code": "TITLE_TOO_LONG", "template": "/jobs/[slug]",
     "urls_rechecked": 200, "pages": 1840, "sampled": true, "covers_task": true, "result": null}
  ]
}
```

Poll `GET /v1/rechecks/{recheck_id}` until `status` is `done`, `failed` or `cancelled`:

```json
{
  "recheck_id": 9188,
  "status": "done",
  "urls_total": 200,
  "pages_crawled": 200,
  "time_capped": false,
  "duplicate_baseline": 9120,
  "urls": [
    {"url": "https://example.com/jobs/senior-accountant-dubai", "status_code": 200,
     "result": "fixed", "reason": null, "redirected": false, "redirect_to": null,
     "issues": [], "new_issues": []}
  ],
  "tasks": [
    {"task_key": "3f9c2a71b0d4e8a6", "code": "TITLE_TOO_LONG", "result": "fixed",
     "urls_failing": 0, "urls_passing": 200, "status": "fixed"}
  ]
}
```

MCP: `verify_fix` takes `site_id` and `task_key` (or `urls`), starts the recheck, polls for up to 60 seconds and returns the results. If the recheck is still running it returns `{recheck_id, status: "running"}`; call `get_recheck` with that id later instead of starting another recheck.

Errors:

| HTTP | `error.code` | Meaning |
| --- | --- | --- |
| 402 | `insufficient_credits` | Not enough credits for the URLs. |
| 404 | `not_found` | No task with this key in the site's latest audit. |
| 409 | `site_not_verified` | Verify site ownership first. |
| 422 | `cannot_verify` | The task's code needs a full audit (or Google, for `INDEX_*` tasks). |
| 422 | `invalid_urls` | A URL is not on the site's host, or the list is empty or over 200. |
| 429 | `recheck_rate_limited` | More than 30 rechecks this hour; see the `Retry-After` header. |
| 503 | `dispatch_failed` | The recheck could not be queued; try again. |
