SEO Monitor API

Monitor SEO score changes over time and get alerted when a page regresses. Add monitors via API, set thresholds, catch drops before they cost rankings. Free tier.

An audit is a snapshot. The real risk is the slow drift — a redesign that strips structured data, a migration that breaks canonicals, a plugin update that tanks performance. The SEO Monitor API watches your URLs continuously and alerts you the moment a score drops past your threshold.

One call

curl -H "X-API-Key: YOUR_KEY" \
  "https://seoscoreapi.com/audit?url=https://example.com"

Or with the Python SDK (pip install seoscoreapi):

from seoscoreapi import audit

result = audit("https://example.com", api_key="YOUR_KEY")
print(result["score"], result["grade"])

Add a monitor, set a threshold

Register any URL as a monitor via the API. The system re-audits it on a schedule, tracks the score history, and fires an alert when the score falls below the floor you set or a critical check regresses — so you hear about it in hours, not at the next quarterly review.

History you can chart

Every monitored URL keeps a score timeline you can pull via API and graph in your own dashboard. Spot the exact deploy that caused a regression instead of guessing.

Frequently asked

How does SEO monitoring work?

You register URLs as monitors via the API. They're re-audited on a schedule, score history is retained, and you're alerted when a score drops below your threshold or a critical check regresses.

Can I get email alerts on a score drop?

Yes. Monitors trigger alerts when a URL regresses past the threshold you set, so you catch problems before they cost rankings.

Is monitoring available on the free tier?

Audits are free (2/day). Score monitoring is a paid feature starting at $5/mo, which includes a monitor allowance that scales with the plan.

Can I chart score history?

Yes — each monitored URL keeps a score timeline you can pull via API and graph in your own dashboard.
