So yeah, well, sort of technically. They do not pass PageRank. We're still passing PageRank through when we link into a page like this. But if it's then blocked in robots.txt, the PageRank goes no further. So we've sort of created a leak and a black hole. So this is quite a heavy-handed solution, although it is easy to implement. Link-level nofollow Link-level nofollow, so by this I mean if we took our links on the main laptops category page, that were pointing to these facets, and we put a nofollow attribute internally on those links, that would have some advantages and disadvantages.
I think a better use case for this would actually be more in the listings case. So imagine if we run a used car website, where we have millions of different used car individual sort of product listings. Now we don't really want Google austria phone number database to be wasting its time on these individual listings, depending on the scale of our site perhaps. But occasionally a celebrity might upload their car or something like that, or a very rare car might be uploaded and that will start to get media links.
in robots.txt because that's external links that we would be squandering in that case. So what we might do is on our internal links to that page we might internally nofollow the link. So that would mean that it can be crawled, but only if it's found, only if Google finds it in some other way, so through an external link or something like that. So we sort of have a halfway house here.
So we don't want to block that page
