Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.

Can you please confirm if you are referring to the FAQ Block in the Gutenberg editor? In the Free version, you can’t reorder the block so you can only insert the FAQ items in the last line. In our PRO plugin, we offer reordering of the FAQ items which is ideal for your situation.

And the main thing how I add sitelink schema markup with rankmath
Getting the sitelinks is an automatic process, we cannot modify the links displayed in the sitelinks.
Please refer to Google’s take here: https://developers.google.com/search/docs/advanced/appearance/sitelinks?hl=en&visit_id=637791834797585697-2104865259&rd=1#sitelinks-best-practices
It’s up to Google if they wish to add sitelinks for your website on the SERP. You just have to have enough authority and backlinks for Google to deem your website worthy of those sitelinks.
If you believe your website is already optimized enough to have those sitelinks, the only thing you can do is wait for Google to include it on the SERP.
Here’s a detailed article that guide you further: https://www.reliablesoft.net/sitelinks/
As for the FAQ inquiry, even if Rank Math added the correct FAQ schema, it will still be Google’s decision if they wish to include it on the SERP.
You would need to have enough domain authority or high-quality backlinks to achieve such a rich snippet or to make the schema work on the SERP.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
