Suppose you want more people to find you through Search Engine Optimization (SEO), but you have no interest in guessing for months. Then the question is not only “which agency?”. The real question is: which SEO approach will generate leads for your commercial goals, and how do we adjust it based on data?
In this article, we walk you through the choices a good SEO agency makes. We explain what you can expect, which steps work for lead generation, and how to avoid your budget disappearing into reports without action.
What exactly does an SEO agency do, and what belongs there and what doesn’t?
An SEO agency can sometimes look like a menu. But quality lies in the execution, the measurement plan, and the link with your sales goal. That is why we always first look at the role of SEO within online marketing and online sales.
SEO as a lead channel, not as a hobby
SEO can generate traffic. But for your business, what happens once people arrive is what counts. That is why we do not make SEO about “rankings” alone. We make it about:
Intent of search queries (do they want information, or do they want quotes?)
Conversion on pages (form, intake, demo, download with follow-up flow)
Quality of incoming requests (Marketing Qualified Leads and Sales Qualified Leads)
Google itself emphasizes that content should primarily be made for people, not for manipulation. Their guidelines for “helpful, reliable, people-first content” are a good foundation here. (developers.google.com)
What you can expect from a professional agency
A strong SEO agency does at least this kind of work, in a logical order:
SEO audit that does not get stuck in technical checklists, but translates into opportunities for lead generation.
Search intent and content planning, including a mapping of pages to stages in the funnel (TOFU, MOFU, BOFU).
On-page SEO, such as structure, internal link logic, headings, content quality and optimizations that are truly aligned with user behavior.
Technical SEO, with focus on indexation, crawlability, canonical choices and page-level performance.
Measurement plan in Google Search Console and analytics, so you can see what works and what does not. (support.google.com)
Iteration, not “one-time optimization.” SEO is an ongoing learning process.
What often goes wrong, and what you should ask
If you notice the agency is mainly busy with:
only monthly reports with positions, without actions
producing content without intent and conversion being worked out
too little attention to proof of experience, for example case material and substantive depth
then you may be on a “rankings as the end goal” track. In the long run, that often leads to disappointment.
Google also uses a quality framework in which “Experience” sits alongside expertise, authority and trust. The point is that content should be credible. (developers.google.com)
The strategy we see as the foundation for SEO agencies
We like to keep it practical. This is the kind of strategy you can expect from an SEO agency that works toward your sales goal.
Step 1, diagnosis on three layers: visibility, relevance, conversion
A good audit does not only check whether Google can find your site. It also checks whether your pages answer the right question, and whether visitors then take action.
Relevance: match between search intent and the answer on the page.
Conversion: CTA in the right place, form of offer, form length, proof and follow-up logic.
Concretely, we always look for pages that already show in Search, but still do not generate enough clicks. In Google Search Console (GSC), you can see how often your site was shown (impressions), how often it was clicked, and what the average position is. Google also explains how these metrics work in the Performance reports. (support.google.com)
Step 2, choose your content based on search intent and revenue potential
We see that many companies plan content based on topics. Topics are good. But search intent is better. Why? Because people in different funnel stages are looking for different answers.
A simple example in lead terms:
TOFU: “what is X”, “X explanation”
MOFU: “X vs Y”, “best way to do X”, “cost of X”
BOFU: “quote X”, “agency X”, “reviews”, “contact”
An SEO agency must be able to translate content into a logical route toward an inquiry. Not just publish. It is about the journey, including internal links and conversion points.
Step 3, build trust: E-E-A-T in content, not as a topping
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness. Google uses this framework as part of quality evaluation, and they have explicitly added Experience. (developers.google.com)
For you, that means practically:
Experience: show what you have done in real projects, with context and choices.
Expertise: support with explanations that are accurate, not vague claims.
Authoritativeness: make sure content does not stand alone, but is logically embedded in your knowledge base.
Trustworthiness: make clear who is responsible, and how the information was created.
This is not a “nice to have.” In our practice, you see that it also directly helps with conversion on landing pages, because people are more likely to leave their details when they understand and trust you.
What you can measure, and how an SEO agency uses KPIs without getting lost
Let’s be honest. KPIs can shape the conversation, but they can also derail it. An SEO agency must use KPIs to make decisions, not to make management sound good.
Start with metrics that truly answer questions
In GSC, the basic story is about impressions, clicks, CTR and average position. Google describes these metrics and how they relate, including CTR as the ratio of clicks to impressions. (developers.google.com)
We usually use this in a way like:
Impressions rise, but clicks do not: then your title and meta or your match with intent is probably not strong enough.
CTR is low: then we test snippet optimizations (title, description) and often also the first content above the fold.
Average position remains stuck: then the problem is often content that does not answer enough, or internal link strength and page architecture.
Note: average position is an average, and Google explains that the position can vary per impression. (support.google.com)
Choose KPIs that lead to leads
For lead generation, we need to connect KPIs to your commercial process. Think about:
Conversion on SEO landing pages (CVR), meaning visitors who start an inquiry or intake.
Qualification: how many requests become Marketing Qualified Leads and then Sales Qualified Leads.
Sales lead time: how quickly follow-up happens, because that affects the final revenue opportunity.
This is where an SEO agency stands out. SEO without lead qualification is like a quote form without a follow-up phone number.
Tracking and reporting: clear, but not overdone
We always ask for a measurement plan. GSC is essential for Search performance. But for lead opportunities, you also need analytics and CRM data. If you use Google Analytics 4 (GA4), we connect events to forms and follow-up actions.
And yes, that also means discipline in definitions. What counts as an “inquiry”? What counts as “confirmed contact”? That has to be consistent, otherwise you are steering on noise.
What an SEO agency delivers in practice, by phase
This is where it gets interesting, because you see what you get. No vague promises, just work you can check.
Phase 1, first 30 to 45 days (from chaos to plan)
A mature SEO agency usually delivers the following in this period:
SEO audit with priorities, impact and effort per topic.
Content and keyword strategy based on search intent and funnel stage.
Technical quick wins (indexation, internal links, content structure) that quickly improve visibility or CTR.
Measurement setup: events, conversions, and how we qualify leads.
If the agency only promises to “do a lot,” but your plan is not concrete, then the chance is high that you later end up discussing what was actually delivered.
Phase 2, 2 to 4 months (build, test, adjust)
This is where most value sits. Think about:
Content production or content optimization with real topics that match intent.
On-page optimizations, including internal link structure, headings and scannability.
Technical optimizations that really matter, for example indexation problems and content duplication.
Conversion improvements on landing pages, such as CTA placement, proof and form logic.
Why does this work? Because SEO rarely has one lever. It is usually a chain of improvements, and each link increases the chance that someone becomes a customer.
Phase 3, ongoing optimization (SEO as a rhythm)
SEO is not a project, it is a rhythm. A good SEO agency regularly runs:
Content updates on pages that are growing or declining.
Experiments on snippets and on content structure for CTR and relevance.
Lead quality conversations with sales, so you know which requests have value.
That is why we keep dashboarding simple. First measure the behavior you can explain, then build complexity.
How do you choose the right SEO agency for your situation?
Okay, now you have a picture of what good looks like. But how do you decide between options without guessing? Use a shortlist of questions that immediately push you toward quality.
Question 1, which SEO opportunities do you connect to lead generation?
You want an answer in terms of pages, intent and conversion. Not just “we do content and technical SEO.” Ask for examples of:
Question 2, how do you use GSC and analytics to make decisions?
A professional agency explains how they work based on data such as clicks, impressions and CTR in GSC. Google explains that the Performance reports provide insight into how often users saw and clicked your site. (support.google.com)
Specifically, ask:
which metrics they review weekly or monthly
which thresholds or signals trigger action (for example low CTR on specific queries)
how they report what was changed and what the effect was
Question 3, how do you safeguard E-E-A-T and content quality?
Google connects quality to people, not tricks. (developers.google.com) In addition, their guidelines show that Experience is part of quality thinking. (developers.google.com)
You want to hear:
where their writing experience comes from
how they fact-check
how they incorporate your own practical stories and cases
Question 4, how do you work together with marketing and sales?
SEO works better when it is connected to the rest of your online marketing machine. Often a combination fits, such as content with Inbound marketing and a consistent follow-up flow.
Question 5, how do you align SEO with other channels without duplicate work?
SEO and paid campaigns can strengthen each other, but only if you let the lead journey speak the same language. Think about landing pages, offer consistency and follow-up timing.
Conclusion, this is how you know whether your SEO agency is right
An SEO agency is good if it does three things at once: visibility, relevance and conversion. Not in theory, but in a plan with priorities, measurement method and iterations.
Ask for concrete actions. Ask for data such as clicks, impressions and CTR in GSC, and how they translate that into improvements. (developers.google.com)
And ask how they build trust according to Google’s quality thinking, including the importance of Experience. (developers.google.com)
If you have that conversation clearly, you avoid “buying SEO,” and you get what it is really about: SEO that contributes to lead generation and sales follow-up. In other words, no magic. Just a system.
