Oh, I completely missed that difference, and I also didn’t click the result (which would have made me realize my mistake). Yeah, your profile is not being indexed by any major search engine as far as I can tell. Unless you recently updated the name on your profile or some such, then I cannot be 100% sure what’s going on. Although, from looking at your user activity, it seems like you made your first public repository in May this year (2020), and your overall activity is minimal. My guess is that Google (and other search engines) haven’t started indexing your profile yet because there are very few inbound links. GitHub isn’t actively telling Google, etc. to index your profile, and they are also not preventing it.
Keep contributing, and be patient — my guess is that your profile will be indexed within a few months.
However, if a few months go by and the situation hasn’t improved, I suggest you submit a support ticket to double check there isn’t anything “weird” going on.
