e-landing page issue

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

The notice is simply a reminder for you to configure your SEO settings for these post types. If you forget to configure them, you might end up indexing a page on the search engine that shouldn’t be or end up with an irrelevant SEO title and meta description — which can most probably affect your search rankings.

Here’s our guide you can follow for that:

Regarding the harmful content, please share the affected URL so we can check as well.

Meanwhile, you can check this helpful thread on how to deal with that error in GSC:

Hope that helps.
