What could be the possible causes of a drop of the average position in a campaign where nothing changed? Does the competition start to play harder?
Lack of fresh content, expired backlinks (moved to deeper pages for example) and like you said - competitors - that some of possible reasons, but I'm sure there are more.
i didn't change anything on the page so i don't know. hope fully sending out few articles with the right anchor link i can make up some...
We are talking about Adwords right? Not natural... there seems to be a little confusion, If you have seen a drop in rank without changing anything then - 1) Your QS has dropped 2) Competitors ad rank has increased (whether it be QS or bid)
