FAQs you should know when hiring an SEM agency
These are two different things and it's important to be clear about them. On one hand there's the advertising investment, which goes entirely to Google every time someone clicks your ad; on the other, the agency fees for managing the campaigns. If they give you a single amount without breakdown, ask for it separately: you need to know how much of your money actually goes to buying clicks.
Google doesn't always show the highest bidder. It combines your bid with the quality of the ad and landing page; if your ad is not very relevant or your website loads poorly, you may rank below a competitor who pays less. Paying is only half of it; the other half is being relevant to what people are searching for.
- Percentage of investment: Usually between 10% and 20% of the monthly budget invested in advertising.
- Fixed monthly fee: An agreed-upon fee, ideal for medium or stable budgets.
- Mixed or performance-based model: A fixed fee plus a variable commission based on achieving objectives or validated leads.
Practically yes, and that's its big difference from SEO: as soon as you activate the campaign, you start appearing. The trade-off is that the day you stop paying, you stop appearing. SEM is an immediate but rented traffic tap; SEO is slower but cumulative. Many businesses combine both.
It's a real risk: competitors or bots clicking your ad to spend your budget without intention to buy. Google detects and refunds a good portion of those clicks automatically, and an attentive agency monitors strange patterns and applies filters. It's not something to obsess over, but it is worth asking how they control it.
- Writing native and persuasive copy in both Catalan and Spanish, avoiding automatic translators.
- Differentiated keyword research, as search volume for a term can vary drastically depending on the language.
- Landing pages adapted to the exact language in which the user clicked to avoid breaking the user experience.
Yes. You can pause and resume whenever you want, and the account retains its history. In fact, that learning history is valuable: an account with track record performs better than a newly created one. That's why it's important that the account is yours and not the agency's, so you don't lose that learning if you ever change hands.
- ROAS (Return on Ad Spend): How many euros you earn for every euro invested.
- CPA / CPL (Cost per Acquisition or Lead): How much it costs you to get a customer to call you or fill out a form in Barcelona.
- Conversion Rate: The percentage of visits that end up performing the desired commercial action.
