A. Search engine optimisation (or SEO) is the process of manipulating a website so that it is more likely to rank highly for a key term that is relevant to your business.
For example, a jewellery business in Perth would strive to be on page 1 for the key term Jewellery Perth.
Why? When someone types these words into a search engine such as Google, they are searching specifically for jewellery in Perth. So if they visit your page, they are more likely to become buyers.
