Answer:
-Buy ad space on a search results page
-Bid for keywords to display your content in search engines
Step-by-step explanation:
Search engine marketing (SEM) is different to search engine optimisation (SEO). In SEM, the business pays to enter an auction. They then bid for advertising space on a website, and whoever wins gets to show their search ad.
Tagging keywords within your content could increase the chance of your website appearing higher up in search engine rankings. This is called search engine optimisation (SEO) and is a free way for Hamish to reach more potential customers.
