What is the effect of enabling versus disabling content caching on SEO, if any? By that, for those who know HTML, I mean, what is the impact of presence versus absence of the following line in your web file, for SEO? <META http-equiv=Cache-Control content=no-cache> For those who don't know what I mean by that, go ahead to Google. Search for any keyword you want to. On the right hand side of each search result, there is a small triangle, clicking which, gives you options such as "cached", "similar" etc. The HTML line I gave above, will remove that "cached" option from there, and ask Google not to cache. My question is, has anyone experimented on whether and how SEO is impacted, by adding or removing that line, or an equivalent of that line? Curious to find out.
