How much does an SEO agency cost?

Most credible SEO agencies work on monthly retainers between 3,000 and 25,000 USD, depending on market competitiveness, number of languages, and how much content and engineering support is included. One-off technical audits and migration work are usually scoped as fixed-price projects.

How long does SEO take to work?

Technical wins can move rankings in four to eight weeks. Meaningful compounding growth in competitive markets typically takes six to twelve months, because search engines need time to crawl, evaluate and trust new content and links.

What is answer engine optimization (AEO)?

Answer engine optimization is the practice of making a brand the source that AI systems quote. It combines clear question-and-answer content structure, schema markup, factual consistency across the web and third-party citations so ChatGPT, Perplexity, Gemini and Google AI Overviews reference you by name.

Can an SEO agency work across different countries?

Yes. International SEO uses hreflang, country-level site architecture, local keyword research and market-specific link acquisition. We run programs for companies in the United States, United Kingdom, Australia, Canada, Ireland and India from one strategy.

How do you measure SEO results?

We report on qualified organic sessions, non-brand keyword coverage, share of AI citations, assisted pipeline and revenue in GA4, Looker Studio and your CRM. Rankings are a diagnostic, not the deliverable.

Do you offer web development and paid media as well as SEO?

Yes. The same team ships Core Web Vitals work, WordPress, Shopify, Webflow and React builds, and performance marketing across Google Ads, paid social and CRO, so organic and paid share one measurement model.

What makes a good SEO agency partner?

Senior people on your account, a written thesis for why each task will move revenue, transparent reporting you can audit, no long lock-in contracts, and a willingness to say no to work that will not compound.

Short answer

What does an SEO agency actually do?

An SEO agency plans and executes the work that makes a website rank in search engines and get quoted by AI answer engines: technical fixes, keyword and entity strategy, content production, internal linking, digital PR and measurement. A good SEO agency ties every task to pipeline and revenue — not rankings alone.

Fix what blocks crawling, indexing and Core Web Vitals before spending a cent on content.

Build topical authority around the questions your buyers actually ask, in every market you sell in.

Earn the citations — links, mentions, reviews — that both Google and LLMs use to decide who to trust.

AEO & GEO

Search did not die. It moved into the answer.

Roughly a third of commercial research now starts inside an AI answer. Ranking is no longer enough — you have to be the source the model quotes. We run SEO, answer engine optimization and generative engine optimization as one program, because they share the same foundation: clean structure, verifiable facts, and citations from places the model already trusts.

The two things that decide whether SEO pays back.

A fast, well-built site and a paid programme that reads the same data. Both are in-house — so nothing gets lost between three vendors blaming each other.

Licences are on us. Dashboards live in your Google account, so the data stays yours the day the engagement ends.

✎

Be wary of any agency whose reporting is a tool dashboard with their logo on it. Tools measure; they do not decide what matters, and every one of these will happily generate a hundred findings that change nothing. What you are paying for is the judgement about which three of those hundred are worth your developers’ time.
