- Encosia 18y agoPageRank is simply a measure of how many pages link to your pages, weighted by their own PageRank. Traffic has nothing (directly) to do with it.
- snprbob86 18y agoI said "page rank", not "PageRank". When you perform a web search, you get a _ranked_ list of pages...
- IsaacSchlueter 18y agoThey don't get traffic data, though. They send a far-future expires header, so they don't even expect that the same user will request it more than once, unless their browser hits the limit on its cache size and deletes the file. The goal is speed, not tracking.
