Why SEO and Keyword Research Are Non-Negotiable for Startups in 2025
Marketing remains one of the most significant challenges for startups, not because the product failed but because the business wasn’t effectively found online. Whether it's a tech-based SaaS or a coffee subscription box, if your target client cannot find your business, success is next to impossible.
Research shows that 68% of all online experiences begin with a search engine query, making SEO the heart of inbound traffic. However, inbound traffic is not just earned; it's fought for, especially now that AI-driven algorithms prioritize semantic relevance over keyword stuffing. This is where tools like SpyFu and SimilarWeb come into play for startups aiming to validate their ideas with minimal marketing budgets.
