We build and run blogs that rank on Google, attract the right readers, and turn consistent content into a real business asset. No fluff — just editorial work that compounds over time.
Real projects, real numbers — here's what happens when strategy meets consistent execution.
SaaS BlogA Madrid-based project management SaaS had no blog presence. We launched a focused editorial strategy around mid-funnel keywords, published 40 articles in 10 months, and grew organic traffic to 28,000 monthly sessions — turning the blog into their top lead generation channel.
E-commerce BlogAn online home goods retailer was relying entirely on paid ads. We built a SEO blog targeting style, design, and interior inspiration keywords. Within 12 months, organic traffic grew 340% and the blog drove 18% of total monthly revenue through affiliate and product integration.
Professional ServicesA Madrid law firm needed authority content to compete with larger national firms. We developed a bilingual blog covering common legal questions in plain language. Today they rank on page one for 14 high-intent search terms and receive 60+ inbound inquiries per month from blog visitors.

From strategy and SEO research to writing, publishing, and analytics — we handle the full editorial stack so you don't have to.
We map out the exact search terms your target readers are typing into Google — then build a content calendar around topics that can actually rank and convert.
Our Madrid-based writers and editors produce long-form, well-researched posts that hold attention, answer real questions, and reflect your brand's voice.
Consistency is the secret to blog growth. We plan, schedule, and manage your publishing pipeline so content goes out on time, every time.
Every post is optimized for structure, meta tags, internal linking, and readability — so search engines understand it and readers enjoy it.
Monthly reports show you traffic trends, top-performing posts, keyword rankings, and what we're adjusting next. No vanity metrics — only data that matters.
Once your blog gains traction, we help you turn it into revenue — through affiliate content, lead magnets, sponsored posts, or gated resources tailored to your niche.
We spend the first week learning your business, audience, and competitors. We audit existing content if you have it and define the blog's unique positioning in your market.
We deliver a 3-month editorial roadmap with prioritized keyword targets, post formats, and publishing cadence — approved by you before a single word is written.
Our editorial team writes, edits, formats, and publishes every post with on-page SEO baked in. You review drafts in a shared workspace and approve before anything goes live.
Monthly performance reviews drive continuous improvement. We double down on what's working, refresh underperforming posts, and expand into new topic clusters as you grow.

We don't believe in content for content's sake. Every post we write has a purpose: a keyword to rank, a reader to convert, a story to tell.
Search engines reward content that readers actually finish and share. Our writers research topics deeply, interview subject-matter experts when needed, and craft posts that are genuinely worth reading — because that's what earns backlinks, trust, and repeat visitors over time.
Research · Depth · Readability
Before we write anything, we know why we're writing it. Each article is mapped to a keyword cluster, linked to a conversion goal, and structured to earn a featured snippet or top-three ranking. Content without strategy is just noise.
Keywords · Structure · Rankings
A blog isn't a one-time project — it's a channel that needs active management. We track performance weekly, refresh old posts that are slipping in rankings, and constantly test new formats, headlines, and CTAs to improve engagement and conversions.
Analytics · Refresh · Growth
CoreStackBase was founded in Madrid by editors and SEO strategists who were tired of seeing great businesses fail online because their blogs were either nonexistent or full of hollow, keyword-stuffed articles. We built a studio around a simple idea: content that is genuinely useful to readers will always outperform content that tries to game an algorithm. Since 2018, we've helped startups, agencies, and local Madrid brands grow blogs that generate real, measurable business results.
Most blogs fail because they lack strategy, consistency, or both. CoreStackBase fixes that. Book a free 30-minute content audit and find out exactly what your blog needs to start growing.
