I ran across this question on Stack Overflow: Stop Search Engine crawling of “tel:” links?
It needs editing, but it appears to me that it would be on topic here, because it has to do with SEO. It is not about coding JavaScript (apparently, somebody didn't tag it correctly). It is not specific to the OP's site, in my opinion.
It might be a little about HTML. I'm not entirely clear on the nature of the problem. But I do see some questions here, such as this one, which seem to have a similar level of HTML-ness involved.
I can't tell if it's a duplicate. I did a search for tel
links and didn't see anything that addressed the problem.
Is the question fit to be migrated?
