How to choose an SEO agency to promote your website

Organic traffic is one of the most stable channels for attracting leads today. It reduces dependence on context and has a long-term effect. At the same time, choosing the wrong contractor can result not only in a lost budget, but also in lost time that cannot be recovered: incorrect links, technical problems, and search engine filters can take months to fix. In this article, we will look at how website promotion works, how to choose a format, what criteria to use when evaluating agencies, and what to look for in a contract so that SEO becomes an investment rather than a lottery.

Website promotion: how to choose a format

In one B2B project, the client changed contractors three years in a row: first, there was an in-house part-time SEO specialist, then a freelancer, then a small agency. Only after evaluating the entire history did we see that no one really linked SEO to the sales funnel, and the tasks were vague. Until the goals were set and the format was determined, the promotion went in circles.

What tasks does SEO actually solve?

SEO should be responsible for increasing visibility for target queries, the quality of organic traffic, and the number of search hits. A classic list of tasks:

• technical soundness of the website and loading speed;
• developing semantics for real customer queries;
• optimising the structure and content for these queries;
• working with behavioural factors and conversion;
• safely increasing link mass.

If an agency only talks about ‘getting you to the top’ and is silent about conversion and leads, this is a reason to ask additional questions.

Working formats: agency, freelancer, in-house

There are several scenarios:

• An in-house specialist is suitable when a company has many SEO tasks, has the resources to hire someone, and has a manager who understands how to set tasks and evaluate results.
• A freelancer is appropriate for small websites or specific tasks: technical audit, one-time optimisation, local promotion.
• It makes sense to choose an SEO agency to promote your website when you need a comprehensive approach: analytics, strategy, content, technical tasks, links, and reporting.

The more complex the niche and the higher the competition, the more important it is to have a team with stable processes, rather than a single specialist who ‘does a little bit of everything.’

When an agency makes sense

An SEO agency is especially justified if:

• the website already has a history and traffic, but needs systematic growth;
• long-term promotion is planned with a combination of SEO, content and technical tasks;
• clear reporting and several competencies are important at the same time: analytics, copywriting, development;
• you are not ready to build your own SEO department and train people.

In such cases, the question of ‘website promotion: how to choose a format’ is almost always decided in favour of an agency rather than a single specialist.

Basic criteria: how to choose an SEO agency

When I am asked to quickly put together a list of agencies for a tender, I start with three simple parameters: experience, case studies, and reputation. If these are lacking or unclear, there is usually no point in looking any further.

Market experience and specialisation

The length of time a company has been in business does not guarantee quality, but it is an indicator of stability. An SEO agency that has been operating for 5-7 years and has survived several major search algorithm updates has already encountered various situations and learned how to deal with them.

It is important that the team has experience in your niche or a related one: promoting an online store is very different from SEO for a local clinic or B2B service. Without industry context, the contractor will learn at your expense.

Portfolio and measurable cases

Good cases are not only beautiful screenshots, but also clear figures:

• traffic dynamics by segment;
• growth in targeted queries in visibility;
• changes in the number of applications and the cost of leads from organic traffic.

It is useful to see if there is:

• a description of the initial situation and tasks;
• a work plan and key hypotheses;
• the period over which the results were achieved;
• comments on risks and limitations.

If the case studies only contain general words, without specific numbers, questions and deadlines, it is difficult to assess the real level.

Reputation and publicity

Reputation is not just about reviews on the agency’s website. The following are also important:

• independent reviews and ratings that list projects and contact persons;
• mentions in industry media, publications, case studies;
• participation of agency speakers in conferences and webinars on SEO and marketing.

Public activity does not guarantee results, but it shows that the team is investing in expertise and is not hiding.

How to evaluate a website promotion approach

In one case, I was approached with the following story: ‘The previous agency promised rapid growth, but after a year, the website was filtered out.’ Analysis revealed a typical set of issues: mass spam link building, aggressive networks, rewritten texts with over-optimisation. It took a year and a half and a new budget to recover.

White SEO versus ‘quick’ schemes

Modern website promotion: how to choose methods is a question of balancing speed and safety. White approaches are based on:

• careful technical optimisation;
• working with relevant content;
• high-quality links from thematic sites;
• improving user behaviour on the website.

Grey and black schemes usually promise rapid growth, but they are short-lived and often end in sanctions: a sudden drop in rankings, loss of some pages from the index. If an agency avoids answering the question ‘how exactly will you promote the website’ and is not ready to discuss the risks, this is a warning sign.

Audit and strategy before launch

One of the key differences of a strong team is the presence of preliminary analysis and a clear starting strategy. Before signing the contract, you should be shown at least in general terms:

• the state of the website from a technical SEO perspective;
• problems with structure and content;
• a rough plan of work for the first 3-6 months;
• an assessment of the growth potential and complexity of the niche.

If, instead, they immediately send you a price list ‘for positions’ and promise ‘top 10 for any keywords’, the approach is likely to be formulaic.

Realistic forecasts

A normal SEO agency does not promise ‘top rankings in a month’ in a competitive niche. Instead, you will receive a realistic forecast:

• guidelines on when to expect the first noticeable results;
• ranges for traffic and request growth with the current budget;
• conditions under which the forecast may not work.

If the forecast looks like a set of beautiful graphs without assumptions and caveats, its value is low.

Team and processes within an SEO agency

In one project, two agencies proposed essentially the same plan, but differed in their approach to implementation. The first had one SEO specialist on the client’s side who was responsible for everything. The second presented a scheme: lead SEO, content editor, technical specialist, link builder, and account manager. In the long run, the second option won, although it was more expensive at the start.

Who is leading the project

Find out who exactly will be working on your website:

• lead SEO specialist and their experience;
• the content team: who writes and edits the texts;
• technical specialists: who edits the code and solves complex tasks;
• the account manager, who is responsible for communication and deadlines.

It is important that SEO does not depend on just one person, otherwise any overload or vacation will affect the project.

Communication and reporting

A mature agency immediately shows how interaction is structured:

• frequency of reports and conference calls;
• reporting format: dashboards, PDF, access to analytics;
• regulations for responding to requests and communication channels.

A good practice is a monthly report with traffic, visibility, and lead metrics, a list of completed work, and a plan of hypotheses for the next period.

Tools and transparency

See what tools they use:

• web analytics and end-to-end analytics systems;
• position and visibility monitoring services;
• tools for auditing, collecting semantics, and tracking links.

The key question is whether you will have access to this data. Transparency in metrics and reports allows you to understand at any time what you are paying for and what is happening with the project.

Money and contracts: what matters at the start

In one of my projects, the business owner signed a contract with an SEO contractor ‘on impulse.’ The agency promised rapid growth and ‘minimal risks,’ the contract was skimmed over, and KPIs were not set. Six months later, it became clear that work was being done, but it was virtually impossible to measure the results. Terminating the contract was not easy: some of the terms were written in favour of the contractor.

Payment models and how to approach them

There are three main models on the market:

• a fixed or subscription fee for a set of services;
• payment for results (positions, traffic, leads);
• a mixed option, where a fixed fee is combined with bonuses for achieving goals.

Fixed fees and subscriptions are suitable for those who want budget stability and transparency in terms of tasks. Payment only for positions or traffic seems attractive, but often provokes the use of aggressive methods and a focus on ‘nice numbers’ rather than the quality of traffic and leads. Ideally, the contract should include a base rate for the work plus reasonable incentives for achieving pre-agreed KPIs.

What should be in the contract

To promote your website consciously, it is important not only to decide which SEO agency to choose for website promotion, but also to put it in writing. A good contract includes:

• a list of works and channels included in the service;
• the timing of the initial audit, implementation of initial changes, and transition to regular mode;
• a list of metrics by which you evaluate progress (traffic, visibility, applications);
• the reporting procedure and communication format;
• terms of termination, notice periods, options for transferring access and work results.

The less specific the contract is and the more vague wording it contains, such as ‘provision of promotion services,’ the higher the risk of disappointment.

How to distinguish a real KP from ‘selling air’

An adequate commercial proposal:

• is based on your website and niche, rather than being a universal presentation;
• contains a brief analysis of the current state, main problems and growth points;
• describes the stages of work, deadlines, benchmarks for results and risks;
• shows how the connection between the work and business metrics will be structured.

If the commercial proposal only contains a list of services unrelated to your situation and focuses on grandiose promises and discounts, it is better to spend your time looking for another candidate.

Common mistakes when choosing an SEO agency

When collecting stories from clients who come to me ‘after a difficult experience,’ I almost always hear the same phrases. This is good material for a checklist of mistakes to avoid.

Choosing based solely on the lowest price

The lowest price rarely means the greatest benefit. Often, low cost is achieved by cutting corners on analytics, strategy, content, and technical improvements — in other words, on the things that produce lasting results.

When you’re thinking about how to choose an SEO agency, compare not only the price, but also the scope of work, experience, and transparency of reporting. The difference in budget at the start can easily be offset by the difference in results a year later.

Focus on promises of ‘top rankings in a month’

Phrases like ‘we’ll get you to the top in 30 days’ in a competitive field usually mean one thing: either deliberately false expectations or aggressive methods that could lead to penalties from search engines.

Mature agencies talk about time frames, development scenarios, and conditions under which the plan may not work. If your questions about risks are answered with only ‘everything will be fine,’ you should be wary.

Lack of clear business goals and technical specifications

Another common mistake: ‘just get us more traffic.’ Without linking to target queries, the funnel, average cheque, and sales plans, SEO becomes a game of numbers for the sake of numbers.

Before starting, it is important to establish:

• business goals (leads, sales, applications);
• target audience and priority areas;
• resource and budget constraints for website improvements.

Then both sides will understand what is considered a success and what is not.

Step-by-step algorithm: how to choose an SEO agency for your website

One of my favourite ways of working with clients is to go through the process together, from ‘we are looking for SEO’ to making an informed choice of contractor. Below is a simplified version of this algorithm.

Step 1. Formulate goals and metrics

Before looking for how to choose an SEO company, determine:

• where you are starting from (traffic, positions, applications);
• where you want to be in 6–12 months;
• what metrics will be key (organic traffic, leads, sales).

This will provide a basis for dialogue with agencies and help you weed out those who only talk about rankings.

Step 2. Compile a shortlist of 3–5 agencies

Use a combination of sources: ratings, reviews, personal recommendations, case studies in specialised media. Record the following for each candidate:

• experience in your niche;
• typical client budgets;
• quality of portfolio and case studies;
• impression from initial contact.

Step 3. Request an audit and commercial proposals

Ask each participant for:

• a basic website audit identifying the main problems;
• a work plan for the first 3–6 months;
• guidelines on deadlines and expected results;
• an example of the report you will receive.

Compare not only the price, but also the depth of analysis, the realism of the approach, and the transparency of the wording.

Step 4. Compare case studies, approaches, and reporting

Take the time to:

• study 2–3 case studies on related topics in detail;
• assess how honestly the complexities and limitations are described;
• compare the structure of reports and the level of detail.

This usually makes it clear who is used to working with business metrics and who is limited to SEO indicators.

Step 5. Hold a conference call or meeting

At the meeting, it is important not only to listen to the presentation, but also to ask questions:

• how the agency sees your risks and growth points;
• what resources will be required from your side;
• how communication will be structured and who is responsible for the result.

The more specific and calm the answers, the higher the trust in the team.

Step 6. Select a contractor and set the terms

At the final stage:

• agree on a list of tasks and priorities for the first period;
• set KPIs and rules for revising the strategy;
• check the contract for all key points;
• agree on the method and timing of transferring access, analytics data and audit results.

This algorithm helps to reduce the emotionality of the choice and rely on facts.

Conclusion and gentle call to action

Choosing an SEO agency is not a competition of beautiful presentations, but a search for a partner who can translate organic traffic into sustainable leads and sales. If you rely on clear criteria, carefully examine case studies, approach, and contract, the chance of making a mistake is significantly reduced.

SEO works over months and years, so what matters more than promises of ‘quick results’ is the team’s ability to think strategically, be honest about risks, and regularly show progress in numbers. If you realise that your website has outgrown its current level of promotion, it makes sense to start with a thorough audit and strategy consultation. This will provide a basis for making an informed choice of contractor and save your budget.
