Frequently asked questions
What does an SEO agency do?
An SEO agency analyses your website and your market, fixes whatever stops Google from crawling and understanding it (technical SEO), creates or improves the content that answers what your customers search for, and gets other trustworthy websites to talk about you. The goal is not just to "show up on Google" but to receive visits that turn into calls, forms or sales.
How long does SEO take to show results?
There is no figure that fits everyone: it depends on how competitive your sector is, the age and state of your website and how much content needs to be created. SEO is a medium-term investment, not a switch: the first movements usually show up before the business results, and anyone promising page one in a few days is selling you smoke. That is why we start with an audit and explain what to expect in your specific case.
How much does an SEO agency in Madrid cost?
It depends on your website's starting point, your sector and the scope of the work (a one-off audit, local SEO and an ongoing strategy do not cost the same). That is why we do not publish a single rate: we first run a free audit and, based on what we find, give you a tailored quote with no small print.
Can you guarantee me the top spot on Google?
No, and be wary of anyone who does: nobody controls Google's algorithm. What we can commit to is the work, the transparency and the follow-up: what is done each month, why, and what effect it has on your visits and enquiries.
What is the difference between SEO and Google Ads?
SEO works on your presence in the organic results: it takes longer, but it accumulates and you do not pay per click. Google Ads puts you at the top by paying per click, with results from day one that disappear when you stop investing. Many companies combine both: ads to sell now and SEO to depend on them less over time.
Do you only work with companies in Madrid?
We are based in Tres Cantos, in the Community of Madrid, and we work with businesses in Madrid and across Spain. If your business depends on local customers, local SEO is probably your best lever; if you sell nationwide or abroad, we plan a national or international strategy.
What is GEO and why should I care?
GEO means optimising your website so search engines and AI assistants (ChatGPT, Gemini, Perplexity) cite you in their answers. More and more people ask an AI directly instead of searching on Google, so we work on both fronts. We explain it in detail on our GEO and SEO for AI page.
Can I see how my website is doing before hiring anything?
Yes. We run a free SEO audit where we review your website's technical state, your content and your local presence, and tell you clearly what to improve and in what order, with no commitment.
