What is the difference between SEO and SEM?

SEO (Search Engine Optimisation) is about earning your free place in Google’s organic listings by having the best content relevant to the search being requested. SEO is about optimising your content and your website to get the best results.

SEM (Search Engine Marketing) is about online adverts. So SEM is about buying traffic and clicks by advertising on search engines (sponsored links), social media platforms and the many websites that run adverts.

SEM advertising campaigns will need Landing Pages on your website that are designed specifically for that advert with a singular focus of getting the best results from the campaign without other distractions.
