Two different ways of doing SEO
Each Tax season in Spain brings the same scenario: a surge in searches concentrated over just a few weeks and fierce competition to capture that traffic.
A quick look at the SERPs reveals two companies using completely opposite models that are working at scale: TaxDown and CaixaBank. Two different business models (tradition and trust versus modernity and speed), two distinct strategies, two ways of understanding SEO… and one common factor that explains their success: the intelligent use of link building.
In this article, we break down the key elements of their strategies that have helped them climb rankings and stand out in LLM results.
TaxDown: fewer clicks, more organic traffic
The TaxDown case is particularly interesting because it breaks with one of the most common SEO approaches: generating large volumes of content. Instead, their strategy is based on reducing the number of URLs and maximizing their performance.
If we analyze SERPs around searches like “hacer la declaración de la renta online” we find TaxDown competing in top 4 positions alongside references such as official pages from the Tax Agency or banks like BBVA; and ranking in first position for very specific long-tail queries such as “cuándo se puede hacer la declaración de la renta”.
This positioning is not accidental. It follows a very clear logic: directly targeting transactional intent. How do they achieve this? Here are some of the key elements:
- Their main pages are not informational articles. They are conversion-focused landing pages, structured on a very solid SEO foundation. They integrate optimized content, FAQs that capture featured snippets, and interactive elements that increase dwell time. Everything happens within a single URL.
- Links are focused on their key pages, those targeting keywords with direct conversion intent. This creates a very specific effect: URLs with significantly higher authority than the niche average.
In this way, URLs already ranking in the top 10 receive targeted boosts from relevant media and quickly scale to the top 3. It is not a volume-based strategy, but a precision-driven one.
Additionally, their presence in media and collaborations reinforces brand signals that carry significant weight in the financial sector. It is not just about links, but context: editorial articles, mentions, and real traffic that consolidate authority.
CaixaBank: institutional authority and content to build trust
CaixaBank’s SEO approach follows a purely institutional logic. Their tax-related content, such as that published on their Esfera platform, is not designed to convert but to position the entity as a reliable source on financial matters.
This shapes their entire strategy. They do not compete for transactional keywords like “hacer la declaración de la renta online” but for broader informational searches such as “tax return 2025.” The goal is not to capture users at the moment of action, but to be present during the information phase.
The key lies in domain authority. CaixaBank starts from a very strong foundation: thousands of historical links, constant media presence, and a widely recognized brand. This allows them to rank content without aggressive SEO optimization or reinforcing each URL with specific link building.
In practice, many of their pages rank not because they are better optimized, but because Google trusts the domain.
Two different paths, One common foundation: links that amplify results
Although the strategies of TaxDown and CaixaBank differ in execution, they share one essential element: link building is not a complement, it is the core of their growth.
- TaxDown uses it to push specific pages with high conversion potential.
- CaixaBank ranks at the domain level, positioning informational content without the need to boost each URL with specific links.
You cannot compete with CaixaBank in authority. But that strength is also its limitation. TaxDown does not try to match a bank’s authority. It plays at a different level: identifying high-intent keywords, creating pages designed to rank, and using link building as a direct lever to climb positions.
While CaixaBank ranks by domain, TaxDown ranks by execution. It reinforces specific URLs with contextual links and manages to scale in SERPs where, in theory, competing against a bank should be much more difficult.
The takeaway is clear: it is not about having more authority, but about knowing where and how to apply it.
How to apply these strategies in a real campaign with Growwer
Putting this analysis into practice first requires understanding what type of strategy you want to build. Replicating one model is not the same as replicating the other, and that decision shapes the entire link-building plan.
If your goal is conversion, the logic should be similar: build one or two extremely strong URLs and concentrate most of your efforts there. Every link matters, and the priority is placing them in media that already have visibility and relevant context.
If your goal is traffic, the approach should be to develop a broad content cluster, cover multiple search intents, and strategically distribute links across different pieces.
However, in practice, the best-performing strategies usually combine both approaches: a well-developed main page acting as the hub, supported by a set of content pieces that capture long-tail queries and reinforce topical authority. Link building is distributed across both levels, always following a clear logic: strengthening what is already close to ranking.
