We have been working for a client for a while and they have acheived good results, but someone has told them that they dont need us anymore now their keywords are all on the first page. They were told that they can stop using us and they will just stay there. So to test this theory they have cut a number of keywords from their list that I usually work on for them each month. We dont want to lose this client, so I need to ensure that these keywords drop like a stone within a week or 2. how can I do this? (If the keywords dont drop, they will stop all SEO services, because they will assume that the advice they have been given is correct!) I know that I could do some work on their competitors for these keywords for a month, but that is a lot of work as I would need to work on around 20 sites for each keyword, I may end up doing this, but I want to know if anyone else knows a better way of doing it?
