Frequently Asked Questions

What are the basic terms of digital marketing?

The most important basic digital marketing terms are SEO, SEM, PPC, CTR, conversion rate, CPC, ROI, ROAS, organic traffic, keyword, landing page, call to action, engagement rate and KPI. Understanding these covers most everyday conversations about marketing performance.

What is the difference between SEO and SEM?

AEO (answer engine optimisation) and GEO (generative engine optimisation) are approaches to getting your content cited by AI tools such as Google AI Overviews, ChatGPT and Perplexity. AEO focuses on direct answers, while GEO covers your brand’s overall visibility and accuracy in AI-generated responses.
