Excuse me for referring to “Hull” in the video the word i was looking for was “Derby” haha. As mentioned in the video there are two issues that need addressing to increase your exposure on Google, both of these are equally important. First is the amount of content on your homepage and the keyword density, 1000 words would be sufficient enough not forgetting the keyword density which should be 4% for the main keywords and search phrases you would like to be found for. Secondly is your websites backlink profile, you need other local authoritative websites linking to yours, these are like votes in the eyes of Google and significantly increase a websites rank.
Note: The home page permalink looks like this”http://trentroofing.co.uk/home/3592812″ when it should be “http://trentroofing.co.uk/” I would message Yell and have them fix that at no cost.
