The online marketing industry is certainly a good one to get into as it is constantly growing year upon year. With technology advancing, and many people now using the internet more and more on a number of devices, it seems logical for companies to market in this way.
There is a huge scope of jobs available within the online marketing industry so even if you do not have experience working with the online marketing sector previously, you may find that skills and experience from a previous job may be useful to you.
If you feel that you are good at managing but do not have a clue about the technical side of marketing, then you may be able to be an office manager or team leader, where you are responsible for ensuring that all programmers /designers etc have the information they need to continue to design and create the website for the client.
The wages for jobs within the online marketing industry are also quite good and there is often many opportunities to move up through the ladders over a relatively short period of time.
