EspañolSEO Services, One Performance Contract
Technical SEO, content, link building, local, international and AI search optimization from one Barcelona agency. You get one contract, one SEO manager and a fee that follows your non-branded rankings.
Why SEO Bought in Pieces Underperforms
Most businesses buy SEO in pieces. A freelancer runs the technical audit, a content agency writes the blog and a third supplier sells links. Each supplier reports its own success, and nobody owns the result you actually pay for: more customers from search.
Search has also changed shape. In a Pew Research Center study of 68,879 Google searches, people clicked a traditional result in 8% of visits when an AI summary appeared, compared with 15% when no summary appeared. Your pages now need to win the ranking and earn a place in the AI answer.
SparkSEO is a performance-oriented SEO agency in Barcelona. We run every service on this page inside one contract with one SEO manager, and our fee follows your non-branded rankings: it rises when your pages climb and falls when they drop.
Visits with a click on a traditional search result
A page that ranks but is never cited in the AI answer loses part of its clicks. Ranking and citation now belong to the same plan.

Our SEO Services
Google's own guide to hiring an SEO lists the work a useful agency provides: a review of content and structure, technical advice, content development, keyword research, expertise in specific markets and optimization for generative AI. Our catalogue covers every item on that list, grouped by the problem each service solves.

We compare each landing page with the top 10 results for its keyword group, close the content gaps and rewrite titles, headings and copy for people first.

eCommerce SEO
Category pages, product pages, faceted navigation (the size, color and price filters that can create thousands of near-duplicate URLs) and product structured data for online stores.

Authority
Earn links from websites that already rank for topics close to yours.
3 servicesLink Building
We earn backlinks from websites that already rank for topics close to yours. We call this contextual authority: one link from a relevant source carries more weight than many links from unrelated sites.
See the link building service
Blogger Outreach
We contact writers who already cover your topic and give them a reason to reference you, such as data, expert comment or a useful resource. We never buy links, because Google's spam policies treat paid links as link spam.

Backlink Audit and Cleanup
We review the links that point to your domain, separate harmful patterns from normal noise and act only where the evidence supports it.
See the backlink audit serviceOur Link Rule
We never buy links. Authority goes only to pages that already deserve to rank, so every new link supports a page that can turn visitors into customers.
Local and International
Win the map pack in your city and the right language version in every market.
4 servicesLocal SEO
Visibility in the map pack, the block of local businesses Google shows next to a map, plus local landing pages and reviews for businesses that serve one city or a few.

See the Google Business Profile service
Multi-Location SEO
One system for chains, franchises and service-area businesses: a location page model, a profile per branch and reporting per location.
See the multi-location SEO service
International SEO
Keyword research per market, hreflang tags (code that tells search engines which language version to show) and URL structures for multilingual websites.

A classic SEO retainer charges the same fee every month. If your rankings rise, you pay the fee. If they stay flat, you pay the fee. If they fall, you still pay the fee. You carry all the risk, and the agency's income does not depend on the outcome.
| When your rankings | Classic SEO retainer | SparkSEO performance model |
|---|---|---|
| Rise | You pay the same fee | ▲ Our fee rises |
| Stay stable | You pay the same fee | ● You pay the base fee only |
| Drop | You still pay the same fee | ▼ Our fee goes down |
| Who carries the risk | You do | We share it with you |
Picture a dental clinic on a fixed retainer for twelve months. The reports list 40 blog posts and 30 new links, yet the implant and orthodontics pages still sit on page two. Every task was delivered, and the business result never arrived.
Google warns business owners that no one can guarantee a #1 ranking and advises them to find another SEO if one promises first place. We agree. A performance model is the honest alternative: no ranking guarantee, but a fee that moves with the outcome.
Google Search Central
One Page, One Keyword Group
We manage each landing page with one approved group of related keywords and measure the group as one unit. You see clear progress for every page you invest in, and a weak page cannot hide behind a strong one.
Non-Branded Keywords Only
Non-branded keywords are searches that do not include your company name. People who search for your name already know you. We count only the searches that bring customers who do not know your business yet.
Your Fee Follows Your Rankings
When rankings improve, our fee rises. When they stay stable, you pay the base fee only. When they drop, our fee goes down. A ranking drop costs us money, so risky shortcuts work against our own interest.
How Our SEO Services Work Together
Single SEO services often fail when they run in isolation. Links pointed at a thin page raise authority that the page cannot turn into customers. New articles on a site with indexing errors can wait weeks before a crawler finds them. A technical fix without a keyword plan improves a page that nobody searches for.
Our services run in a fixed order, and each step prepares the next one. Authority goes only to pages that already deserve to rank.
A service business publishes a new blog post every week, but a template setting blocks its category pages from the index. The posts never pass authority to the pages that sell, and a year of writing produces almost no leads.
Keywords and AI Prompts Audit
We find the queries and prompts your future customers use and order them by difficulty, so early wins build the authority you need for harder terms.
Site Audit and Competitor Analysis
We compare each landing page with the top 10 results for its keyword group and list the content gaps to close.
On-Site and Technical SEO
We fix titles, headings, schema, internal links, errors and speed, so bots read the same page that people read.
Off-Site SEO and Backlinks
We build contextual authority through blogger outreach once each page is the best answer for its keyword group.
Questions About Our SEO Services
Which SEO service should I start with?
Most websites start with the SEO Audit or with Keyword and AI Prompt Research. Both produce a plan with realistic estimates, and the plan shows which other services your site needs. A site with clean technical health can move straight to content and authority work.
Can I combine several services?
Yes. Every service runs inside the same contract, with one SEO manager and one report. You do not need to coordinate separate suppliers or compare their reports.
Do all services use the performance model?
Ongoing services do: the fee follows the keyword groups of the landing pages we manage. One-off projects such as an audit have a fixed price, because they produce a deliverable, not a ranking.
How much do SEO services cost?
The price depends on the number of landing pages and on the competition in their keyword groups. Every plan has a base fee plus a performance part that follows the rankings of each landing page. Your SEO manager sends a written plan and price after reviewing your site, so you know the full cost before you sign.
What should I check before hiring an SEO service?
Three checks protect your budget. First, find out what you pay for: hours, deliverables or results on agreed keywords. Second, ask whether reports measure each landing page on non-branded keywords, because branded searches come from people who already know you. Third, ask how the agency earns links. Google's spam policies treat bought links as link spam, and a penalty can erase years of work.
Do you guarantee first place on Google?
No. Google states that no one can guarantee a #1 ranking, and we agree. We commit to a transparent method and link our fee to the outcome instead.
Do your services cover AI search as well as Google and Bing?
Yes. Google confirms that its AI Overviews and AI Mode are rooted in its core ranking systems, so strong SEO is the base for AI visibility. We add prompt research and citation tracking on top of that base.
How fast will I see results?
It depends on the competition in your sector and on the starting point of your site. Your keyword roadmap gives a realistic estimate per keyword group before any work starts.
