Technical recommendation before publishing
Before uploading it, I would especially review these 3 points:
- Scan the actual cookies of mastertecvisual.es, because the table may vary depending on active plugins, forms, Analytics, reCAPTCHA, pixels, or scripts.
- Check the domain of analytical cookies, because in the table they appear as
.mastertec.es, but the indicated Website ismastertecvisual.es. If there is no cross-domain configuration, it could be outdated or poorly documented. - Review
_gat_UA-*, because it refers to Universal Analytics, a system that Google replaced with GA4. If this cookie still appears, it may be due to an old script; if it no longer appears in the scan, it should be removed from the table.
