# How do you build technical SEO monitoring for a large website?

> Automate monitoring of:

- status codes;

- canonical;

- noindex;

- robots;

- sitemap URLs;

- internal links;

- rendering;

- structured data;

- hreflang;

- Core Web Vitals;

- server errors.

Set thresholds based on historical baselines rather than arbitrary numbers.

Example:

`IF noindex pages increase > 20%
ALERT SEO
`
or:

`IF canonical mismatch rate increases materially
ALERT SEO + Engineering
`
Monitoring should detect regressions before they become traffic problems.
