What is the best way I can improve my B2B website?
One of the main problems of SEO is that not many of its techniques cater to the development of B2B websites. I have been struggling to keep up to the competition in the domain. My website mainly caters to consumer product corporate offering them retail solutions. However, since the last couple of months, traffic has been consistently falling. One of the key changes I am trying to inculcate is to target more specific audiences and increase conversion ratio? Can you offer me some tips for this task?
