As someone who works in SEO on a daily basis, I like to think I can spot techniques and/or content applied to a website specifically for that purpose. But in actual fact, it really shouldn’t ever be all that obvious because pages are supposed to be, as Google’s guidelines tell us, designed for human users primarily. This means that meta title, description and other page elements you include for search engines, should not be “stick out off the page obvious,” but should actually look as though they are there for a reason!
