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.

Updated 8 October 2026View as Markdown

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). 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 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 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

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:

{
  "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:

{
  "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.
