About RankLab.
RankLab is a results‑obsessed SEO agency built for brands that refuse to settle for “good enough.” Founded in 2018 by Quan Vu. I started with one simple idea: search traffic only matters if it fuels real‑world growth. Today, we turn that idea into daily wins for clients across SaaS, fintech, e‑commerce, and retail clients.






How RankLab helps businesses win
We dig deep into your website to find exactly where you're losing potential customers. Whether it's technical issues, content that misses the mark, or getting buried by competitors, we spot the gaps that cost you revenue.
We also build relationships with trusted publications in your industry to earn quality backlinks. This builds your credibility with both Google and your potential customers. Everything we do focuses on one thing: generating leads, sales, and real business growth. You'll always see exactly how our work connects to your bottom line.

Our values, it’s simple!
Outcome > Output
We measure success by the revenue our work drives—not by the volume of tasks completed.
Candor
Honest insights, clear next steps, no jargon. If something isn’t working, you’ll hear it straight from us first.
Relentless Learning
Search never stands still, and neither do we. Weekly R&D sprints keep our playbooks one step ahead of algorithm shifts.
Shared Wins
Your KPIs become our scorecard. We celebrate client growth like our own and reinvest lessons across every project.
