Why does choosing the right SEO agency matter?
Well, the answer may seem obvious, yet we think it's worth spelling out as a starting point. A bad choice can mean more than just wasted marketing budget: the consequences can be far more serious. Using unsuitable or outright harmful SEO techniques can hurt how your website shows up in search engines even over the long term, and fixing that can take months or even years.
In recent years many Hungarian businesses have found that the "experts" they hired used outdated, black hat techniques (ones penalized by Google) that may have brought striking results at first, but later caused the website to disappear entirely from the search results.
Google's constantly updated algorithms filter out manipulative solutions more and more effectively.
The right SEO agency, on the other hand:
- Brings real, measurable results.
- Helps you build your online sales channel.
- Uses its expertise to speed up your business's growth.
- Spares you from paying an expensive "tuition fee" in learning the hard way.
- Works with up-to-date strategies.
So let's look at the factors worth keeping in mind so you can find the SEO agency that's right for you!
1. Don't fall for slogans that promise "fast results"
Watch out! Red flag number one: the promise of instant, guaranteed results.
Search engine optimization isn't magic, it's methodical work that takes time. As we detailed in our article on the basics of SEO, "SEO Basics: Everything You Need to Know for Long-Term Success", the results of search engine optimization typically show up on a scale of months, not days or weeks.
Trustworthy SEO agencies communicate honestly about timeframes:
- They set realistic expectations.
- They explain that the first 1-3 months are often about laying the technical groundwork.
- They don't promise a guaranteed first place by a specific deadline.
A genuine expert will never commit to something like "we'll get your website onto the first page in 30 days" or "100% guarantee of a first-place ranking". If you come across promises like these, it's an immediate warning sign.
Google algorithm updates can have a very serious impact on a website's ranking. According to data from recent years, SEO strategies built on fast, unsustainable results are especially vulnerable: an analysis by Search Engine Journal showed that after the 2022 Google updates, sites using manipulative link-building techniques could suffer traffic losses of up to 70%, and some disappeared from the search results entirely.
Clawing your way back then eats up far more time and resources than what you thought you'd saved at the start. That's why it's especially important to choose an agency that optimizes for long-term, sustainable results rather than quick wins.
2. Examine references and case studies
A credible SEO agency proudly showcases its past work, with the clients' consent, of course. Don't settle for the reference logos listed on the website: ask for detailed case studies with concrete results and data.
What to look for in case studies:
- Success stories from businesses of a similar size or in a similar industry
- Concrete, measurable results (e.g. growth in organic traffic, an increase in the number of conversions)
- A detailed account of the challenges and the solutions
- The duration of the project and how long it took for results to appear
It's good practice to pick 2-3 references and reach out to these businesses directly: most company leaders are happy to share their experiences. This kind of first-hand information is often worth more than any marketing material. Ask how the collaboration went, how satisfied they were with the communication, and above all what real business results the SEO work brought them.
3. Ask for full transparency about the methodology
Trustworthy SEO agencies don't wrap their work in a magical fog: they're happy to share with you, in detail, what methodology they follow, what tools they use and how they build the strategy.
Important questions you should definitely ask:
- How do they build the search engine optimization strategy?
- What keyword research methodology do they use?
- How do they approach the technical SEO audit?
- What content development guidelines do they follow?
- What link-building strategy do they use?
It's especially worth asking in detail about their link-building practice, since this is one of the most important and most complex areas of search engine optimization. A professionally grounded link-building strategy usually combines several methods: building industry relationships, creating valuable content, PR activity and forming natural partnerships. A profit-focused SEO partner can explain in detail what types of links they plan to acquire, through what sources, and why they're concentrating on exactly those. If, on the other hand, they avoid concrete answers in this area or use vague terms, that can be a warning sign.
4. Understand the SEO agency's reporting and measurement methods
Professional SEO agencies produce regular, detailed and understandable reports that contain not just numbers, but also their interpretation and concrete next steps.
What to expect from the reports:
- They should be regular, usually reported on monthly.
- They should be built on clear KPIs (e.g. change in organic traffic, keyword rankings).
- They should show not just what happened, but also "why" it happened.
- As part of the report, they should also identify concrete action plans.
- The whole communication should be understandable and free of jargon.
It's worth asking for a sample report before signing a contract so you can see how transparent and understandable their communication is. The best agencies produce reports that are easy to interpret not just for marketing professionals, but for other members of the leadership team too.
5. Watch how hard they work to understand your business
Real SEO experts don't offer generic solutions: they work to deeply understand your business's goals, target audience, industry specifics and competitors. This deeper understanding is what makes it possible for the strategy to genuinely fit your specific business needs.
It's a good sign if the potential partner:
- Asks thorough questions in the first meeting, instead of just presenting.
- Asks for your business plans and strategic goals.
- Takes an interest in your buyer personas and typical customers.
- Analyzes your competitors even before making an offer.
- Takes the time to get to know the specifics of your industry.
An SEO specialist can do technically flawless work (fast loading time, mobile-friendly design, a proper HTML structure), but if they don't thoroughly know the specifics of your industry, the end result will fall far short of what's optimally achievable. Keyword selection, content strategy and the whole communication approach have to fit the unique characteristics of your sector, since a healthcare service, for example, comes with completely different search habits, trust-building requirements and decision-making processes than a construction company or a fashion brand.
6. Watch the SEO agency's communication
The quote request and negotiation phase is an excellent preview of what the later collaboration will be like. If there are already problems with communication at this stage, they'll only get worse over the course of the future partnership.
Watch for the following:
- How quickly do they respond to inquiries?
- How thoroughly do they answer your questions?
- Do they make an effort to translate jargon into plain language?
- How flexible are they about the timing of meetings and calls?
- Do they proactively ask questions, or just respond passively?
A good SEO agency treats you as a partner, not "just a client". You should be able to sense this in the very first communications.
7. Avoid SEO agencies offering flat-rate, one-size-fits-all packages
SEO isn't a boxed product: every business has unique challenges and opportunities. Pre-assembled, fixed-price "Gold-Silver-Bronze" type packages usually don't offer tailored solutions.
Examine the following:
- Does the offer take into account the current state of your website?
- Does the strategy align with your specific business goals?
- Are they flexible in putting the services together?
- Do they justify why you need exactly those activities?
Professional SEO agencies usually run an audit first, then make a tailored offer based on its results. This means that before signing a contract, they thoroughly analyze your website and your online presence.
8. Check the expertise of the SEO agency's team
SEO is a dynamically changing field where continuous learning and keeping pace with algorithm updates are essential. The team of a truly professional agency isn't just experienced, but actively develops its knowledge too.
Assess the following aspects:
- The team members' specialization and area of expertise (technical SEO, content development, link building): a well-rounded team is an advantage.
- Professional certifications and qualifications (Google Analytics, Google Ads, professional training courses).
- The agency's knowledge-sharing practice (professional blogs, case studies, conference talks)
- Participation in industry events and professional forums
- How up-to-date and high-quality the SEO tools used by the agency are.
Being up to date is especially important, since what was a proven SEO practice 2-3 years ago can even be a disadvantage today. For example, Google's 2023 "Helpful Content" update significantly changed content development strategies, and specialists who keep applying the earlier methods are now less able to achieve competitive results.
9. Assess the full service range and the opportunities to work together
SEO doesn't happen in a vacuum: it's closely connected to the entire digital marketing ecosystem. It can be an advantage if, beyond search engine optimization, the agency also has experience in other areas, because these can bring multiplier business benefits for your company. During the quote request process, watch for whether they talk about the following cross-functional activities of theirs:
- Aligning SEO and content marketing
- Using SEO and PPC (paid ads) strategies to complement each other
- Coordinating social media and SEO activities
- Web development expertise to handle technical SEO challenges
It's important, though, not to look for a "jack-of-all-trades" agency, but for one that excels in SEO while also understanding how it connects to other marketing areas.
10. Have a clear contract that spells out responsibilities and expectations
To avoid misunderstandings and later friction, it's essential to sign a detailed contract with the SEO agency you choose, one that covers every important aspect.
The contract should definitely include:
- A detailed description of the specific activities.
- A realistic formulation of the expected results (avoiding specific ranking promises).
- The frequency and content of reporting.
- The method and frequency of communication.
- A precise definition of each party's responsibilities.
- The conditions for terminating the collaboration.
- The duration of the contract and the conditions for renewal.
Next steps
A good SEO agency doesn't just improve your visibility in search engines: as a real business partner it helps you deliver your digital growth strategy. If you've already identified several agencies as potential partners, use the checklist below to make the final decision:
- Ask potential partners for a detailed offer and strategic plan.
- Ask for and check at least 2-3 references from every agency.
- Meet the future project team in person (or on a video call) as part of SEO consulting.
- Ask for a sample report to get to know the format of the regular reports.
- Check the agency's own online presence and its search positions.
Don't forget that the foundation of every successful collaboration is mutual trust, transparent communication and a clear definition of shared goals. By choosing the right SEO partner, your business gains a resource that provides a significant competitive advantage in the digital space over the long term. It's worth taking the time over the selection process, because it pays off many times over.
