What is the best and easiest way to provide something like the H1 tag but in a way that it doesn't affect google rankings? Our homepage sometimes is used for advertisement, this should be in the H1 which is normally used for the default content that describes the company.
But we don't want that search engines list us with these ads. Do we have to replace the H1 with something else, for example CSS with big font and bold or is there another way to avoid it?
