sitelink searchbox valid items decreasing

Hello,

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

Can you please share your website URL with us so we can further check it on our end?

Please note that, even though Rank Math adds the correct sitelink schema, it’s up to Google if they wish to include your website’s sitelink snippet onto 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.

Looking forward to helping you with this one. Thank you.

Hello,

Thank you for providing your website URL.

Upon inspecting it in Google’s Rich Result Test, your website returns with no error and the sitelink searchbox is perfectly valid as you can see in this screenshot:

Another thing to note is that Google brings a new algorithmic update several times a month and the chances are great that your website got hit by that. You may refer to our Google update page here: https://rankmath.com/kb/google-algorithm-updates/

We have a full guide on that: https://rankmath.com/blog/google-algorithm-update-recovery/

You may follow the guide above or if you feel that your website is already optimized for sitelink searchbox, you may give it a couple of weeks and see if Google brings back your sitelink impression.

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
