I`m working on a webpage which has a "Read More" tab in the main content. Will Google read the content hidden by this tab - or will it be skipped?
+ It should. As long as the hidden content gets rendered as the page loads then you are fine. However, if you are using some JS script that retrieves content on "call" using ids the you will have big problems.
depends how its coded, but, it may well be read properly. We certainly have jquery scripts that do this sort of thing that are read as normal
