Search Engine Marketing vs Search Engine Optimisation

Search engine marketing (SEM) and search engine optimisation (SEO) get talked about like they’re the same thing, but they’re not, and understanding the difference matters if you want your marketing budget working as hard as possible. In this video, Fran breaks down what each one actually involves and how they fit together.

What is Search Engine Optimisation (SEO)?

SEO is the practice of improving your website so it ranks higher in organic (unpaid) search results. It’s a long-term investment: build authority, publish useful content, and get the technical fundamentals right, and your visibility compounds over time without an ongoing spend per click.

What is Search Engine Marketing (SEM)?

SEM is the paid side of search, running ads through platforms like Google Ads so your business appears at the top of results immediately. It’s fast, but the visibility stops the moment you stop paying.

Why the Two Work Best Together

The strongest search strategies use both. SEM gets you immediate visibility while your SEO is being built up in the background, and the data from your paid campaigns, which keywords convert, what messaging resonates, can directly inform your organic content strategy.

Getting the Balance Right for Your Business

How much to invest in each depends on your timeline, budget, and competitive landscape. A newer business with a limited runway often needs SEM to generate traffic while SEO matures. A more established brand with content already ranking might lean further into SEO for a stronger long-term return.
