Why do Mailgun sending domains need SEO consideration?

Mailgun routes transactional email via sending subdomains (e.g. mg.yourdomain.com) that Mailgun generates for click-tracking and unsubscribe links. These subdomains should be excluded from Google Search Console and given robots meta noindex where necessary — otherwise you risk tracking subdomains appearing in search results and diluting your canonical signal on marketing pages.

How does Mailgun click-tracking affect canonical SEO?

Mailgun rewrites click-tracking links through mg.link or your custom tracking domain. If users share tracked URLs in social posts or forums, indexed tracking URLs can appear alongside your canonical marketing page URLs in search results. DeepSEOAnalysis checks whether your public-facing pages carry the correct canonical link element pointing to the primary URL, protecting against tracked-URL indexation.

Can DeepSEOAnalysis audit Mailgun email documentation pages?

Yes — Mailgun developer documentation, integration guides, and API reference pages are crawlable content. DeepSEOAnalysis audits heading structure, meta description quality, internal linking, page speed, and structured data across any publicly indexed content including documentation sites that use Mailgun for transactional email.

What structured data matters for transactional email product pages?

SoftwareApplication or Product schema on email API pricing and feature pages helps Google understand what your product does and at what price point. If your site includes customer review sections, AggregateRating in Product schema can generate rich result stars. DeepSEOAnalysis validates that your schema is server-rendered in the initial HTML response — not injected by JavaScript after page load, which Mailgun's own documentation pages can sometimes do when built on client-side frameworks.
