SCA Brasil case study: authority architecture in Brazil's fuel market, with SEO, GEO and AEO

• 2025is the year the partnership began: since January, Flowup has led the strategic evolution of SCA Brasil's digital ecosystem.
• 5xmore keywords in the Top 10 in 12 months: from 8 to 43 positions (Semrush, Brazil database, July 2025 to July 2026, continuous series, no windows).
• 51%of the project's 395 keywords show an AI Overview on the SERP (Semrush, August 2026): the most AI-heavy results page in Flowup's portfolio.
• 3,400organic clicks and 298,000 impressions, adding up the two measurement windows (102 days, Search Console).
• 1,800clicks in the 20 measured days of March 2026 alone, more than half of the total, at the project's current pace (200,000 impressions in the same period).
• 59%CTR on the branded query, with an average position of 1.19: the highest branded CTR among the case studies published by Flowup.

Two readings complete the picture. First: the average position went from about 20 (July 2025) to 5.7 (March 2026), the effect of authority architecture on the average ranking of a domain with more than a thousand active pages. Second: in the Semrush data, besides the 51% with an AI Overview, 90% of the keywords trigger People Also Ask and the domain holds 5 featured snippets. In the fuel market, the SERP is already an answer environment, and that is where the project works.

Methodology: Search Console, scabrasil.com.br property, web search, two measurement windows (June 1 to August 18, 2025 and February 17 to March 20, 2026, 102 days). The property was migrated in between, and the period without measurement was neither estimated nor interpolated. Semrush, Brazil database, series from July 2025 to July 2026 and snapshot from August 2026. Brand terms (“sca brasil”, “sca etanol” and variants) and the ambiguous acronym “sca” are excluded from the non-branded figures; values are rounded conservatively.

Growth comes from an editorial portal run at newsroom pace: more than a thousand URLs receiving organic traffic (the Search Console export hits its ceiling of a thousand rows), covering fuel prices and imports, mills, biodiesel, fertilizers and the ethanol agenda. The result shows up where it matters most: in the macro questions the market itself asks Google, which SCA is the first to answer.

The selection below shows that territory, with the average positions for the period and with the branded queries (and the acronym “sca”) left out:

When the market asks Google where Brazil's gasoline comes from, the first to answer is SCA's portal. That is what editorial authority means: becoming the answer to the industry's own questions.

• SCA Brasil: Official AI Knowledge Base

  An official reference repository published on the domain: it directs AI systems and search engines to consult the primary sources, with explicit direction to the official URLs and correct citation. See SCA Brasil's Knowledge Base.

• Canonical source and citation model

  Parent pages defined as the official truth of the business, a hierarchy of entities (company, units, history, press) and a citation model for each type of query, so that search engines and LLMs know which SCA this is, and what to cite from where.

These layers work as a semantic contract: they state who SCA Brasil is, what it does and where each piece of official information lives. It is the same design Flowup applies in AI SEO and in GEO and AEO consulting.
