As someone who has worked with a SEO company for four years, I was relatively sad when I was told that the company was closing (apparently they were going to switch their focus to something other than SEO). I have since found a new company that I am very happy with, but it is frustrating to find so many people online who claim to have SEO knowledge, and there are just instant red flags. These are a few of mine, and I hope you can share some of your own so we can build a list for future reference. • Their blog content is copied and pasted from elsewhere. • They don’t rank. • The SEO ranks but their site is spammy and has no original content • The SEO’s clients all link to each other, or their clients’ website/blog links out to random, non-related stuff. • They’re spouting corporate/digital marketing speak but it isn’t really making any sense. If you have anyone like this, dump them. Find yourself a reputable digital marketing agency and get more benefits from it.
