3. Types of Agencies and What to Consider
Type of Agency | What They Offer | Who It’s Best For | What to Look Out For |
Full-Service | Businesses needing a comprehensive approach | Experience across multiple marketing channels | |
Specialized | Businesses that need to solve a specific issue | Limited range of services | |
Web & Marketing | Website creation with parallel promotion | Companies launching a new website or redesign | Whether they perform website audits and improvements |
Digital Agency | Online advertising, digital strategies, analytics | Businesses focused on online promotion | Team expertise: PPC specialists, designers, analysts |
Full-Service vs. Specialized Agencies
Web and Marketing Agency
Ideal if you are creating a new website or redesigning it while planning a large-scale ad campaign.
Make sure they offer website analysis and improvement to fix any technical or UX issues.
Digital Agency
Suitable for those who want to focus entirely on online advertising and digital strategies (email marketing, targeting, content).
Compare who is on the team: copywriters, designers, PPC experts, analysts.
4. How to Choose an Agency: A Step-by-Step Guide
Define Your Goals and Budget
What results do you want: more sales, brand awareness, or traffic?
How much are you willing to invest in online marketing services, considering paid ads?
Check Experience and Case Studies
Request a portfolio: even if some case studies are protected by NDAs, the agency can usually provide general figures or examples.
Check if they have experience in your industry.
Clarify the Communication Format
How often will you receive reports? What KPIs (CTR, ROI, number of leads) will be key?
Who on the team will manage your project, and will you have a dedicated project manager?
Ask About “Website Analysis and Improvement”
Will they audit your website? Sometimes, an inconvenient interface can drive away potential clients, making internet advertising less effective.

Start with a Test Project
Choose 1–2 channels (for example, a minimal package: SEO + a small PPC campaign) and see what results the agency delivers in one to two months.
Evaluate their response time, report quality, and flexibility in their approach.
5. Why Estonian Agencies Can Be a Great Option
Lower Taxes and Higher Competition
In some European countries, taxes are significantly higher, which increases service costs. In Estonia, taxes are lower, and competition among agencies is high—this often reduces the average “price tag.”
Access to Experts at Competitive Rates
The cost of living in Estonia is lower than in major EU economic hubs, so specialists often offer high-quality services at a relatively lower price.
This Is Not an Advertisement
We remind you that the choice depends on your needs and budget. However, it’s worth considering agencies in countries with lower tax rates and high competition, such as Estonia. One example of such an agency is b2bspace.ee—a team that offers comprehensive online marketing services for businesses of various sizes: from in-depth analysis to strategy development and implementation.
