SEA — search engine advertising — means paying for placement in search results rather than earning it. In German-speaking markets the term is used more often than "PPC"; in practice it usually means Google Ads.
How the auction works
You do not simply outbid competitors. Placement is decided by your bid combined with a quality assessment: how relevant your ad is to the query, how likely it is to be clicked, and how well the landing page matches what the ad promised.
The practical consequence is that a more relevant advertiser can pay less per click for a better position. Improving relevance is usually cheaper than raising bids.
What you pay for
Normally per click, not per impression. Being shown costs nothing; being clicked does — whether or not the visitor was ever a genuine prospect.
That is the core risk. Money leaves your account the moment someone clicks, regardless of what happens next.
Where budgets get wasted
Broad matching without negatives. Google interprets intent generously. Without a growing negative keyword list, you pay for searches unrelated to what you sell.
Mismatched landing pages. An ad promising a specific service that lands on a general home page wastes most of the clicks it earns.
Untested conversion tracking. If you count button clicks rather than confirmed submissions, every optimisation decision afterwards rests on inflated data.
Ignoring the search terms report. The queries that actually triggered your ads always contain surprises. Not reading it is how budgets quietly drain.
When SEA makes sense
- you need results now rather than in six months
- you are testing whether demand exists before larger investment
- the term is commercially valuable and organically out of reach
- you have a time-limited offer, event or launch
- you want search data quickly to inform an SEO strategy
When it does not
If the budget is too small to gather meaningful data, if your margins cannot support the click prices in your category, or if the landing experience is not ready, spending on ads mainly buys evidence that something else needed fixing first.
SEA and SEO together
They complement each other. SEA gives immediate visibility and hard data about which queries convert; that data makes SEO prioritisation far better. SEO builds an asset that keeps working when the budget stops.
Is SEA expensive?
Cost per click varies enormously by industry. What matters is whether a click produces enough value, not the headline price.
How much budget do we need to start?
Enough for the data to mean something. We generally suggest at least a four-figure monthly media budget before conclusions are reliable.
Can we run ads ourselves?
Yes, and many businesses do. The common failures are broad match without negatives, no conversion tracking, and never reading the search terms report.
