How to Choose a Marketing Agency: What to Look For Before You Sign

TL;DR: Choose a marketing agency based on three things: whether they have solved your specific problem before, how long they keep their clients, and how they measure results. An agency that cannot show you real results from a real client is not worth your retainer.

Start with your problem, not the agency

Most businesses start by searching for a marketing agency and browsing websites. This is the wrong starting point. Before looking at any agency, write down one sentence describing the problem you need solved.

“We are not appearing on Google for our main service.” “We get website traffic but no enquiries.” “We have no consistent social media presence.” These are specific problems, and the agency you hire should have solved that exact problem for another client before working with you.

An agency with ten years of experience in brand identity will not solve your Google visibility problem, regardless of how good their portfolio looks. Specialty matters more than size, years in business, or number of clients on their homepage.

Three things that separate good agencies from average ones

The first is a track record for your specific problem. Ask to see one or two examples of clients who came in with the same challenge you have. The right answer includes real numbers, traffic before and after, leads generated, and revenue attributed to their work. A car rental business in Albania came to us with one clear problem: they were not appearing on Google at all for their core keywords. After three months of SEO work the site was on the first page. After six months it ranked first for a high-volume keyword in their market. That result is specific, verifiable, and directly tied to the problem they came in with.

The second is long-term client relationships. The best indicator of an agency’s quality is not their awards or client logos. It is how long they keep their clients. An agency that retains clients for two or three years has earned that by producing consistent results. One that cycles through clients every few months is either underdelivering or overselling. Ask directly: who is your oldest client and how long have you worked together?

The third is a combined approach to growth. SEO alone, Google Ads alone, or social media alone each produce partial results. The agencies that consistently produce the strongest growth treat these channels as a connected system. A business ranking organically for a keyword and running a targeted Google Ads campaign for the same query captures far more of the available search demand than either channel alone. Ask whether the agency thinks in terms of a full strategy or manages one channel in isolation.

Questions to ask on the first call

The first call is your opportunity to evaluate the agency, not the other way around.

Can you show me a case study from a business with the same problem I have? This filters out generalists immediately.

Who will actually work on my account day to day? Senior strategists often sell the contract and hand delivery to junior staff. Confirm who your contact is from the start.

How do you measure results? The answer should reference business outcomes, leads, revenue, and organic traffic growth, not impressions or follower counts.

What happens to my assets if we stop working together? You should retain full ownership of all content, ad accounts, analytics access, and any work produced during the partnership.

How do you handle a difficult period, such as a Google algorithm update or a campaign that is not converting? Any honest agency has navigated these situations. Their answer tells you more about how they operate than their pitch ever will.

What good reporting looks like

A monthly report should tell you whether the work is producing real business results. Good reports cover organic traffic growth broken down by new versus returning visitors, leads or enquiries attributed to each channel, and changes in rankings for your target keywords.

Bad reports fill pages with impressions, domain authority scores, and rankings for terms that nobody searches. These metrics look like activity without translating to business growth. If an agency cannot show you the revenue or leads their work has generated for a real client, either they do not track it or the number is not worth sharing.

Our SEO service is built around tracking the metrics that matter to a business, organic sessions from new users, conversion rate from organic traffic, and revenue tied directly to Search Console and Analytics data.

Red flags to walk away from

Guaranteed rankings or guaranteed results. No agency can guarantee a specific position on Google. Anyone who does is either overpromising or using tactics that will eventually damage your site.

Retainers under €200 per month. At that price point you are getting automated tools and outsourced content, not a real strategy. The damage from poorly managed campaigns can cost more to fix than doing nothing at all.

No clear reporting structure. If an agency cannot tell you upfront how they will measure and report results, they are not planning to be accountable for them.

Pressure to sign quickly. A good agency is confident enough in their work that they do not need to rush you into a contract.
