21 Best SEO Companies 2021 – Built In

Once a Google insider’s secret, SEO has become one of the marketing industry’s most popular tools. According to Search Engine Journal, SEO itself gained traction during the late 1990s, during which time early websites grew frustrated over the fight for search engine dominance. Back then, SEO strategy was largely defined by “keyword stuffing,” HTML tags, and internal and external linking. 
Yet, for modern-day websites, cramming a huge number of keywords into a piece of content isn’t good SEO. Our present-day understanding of SEO takes into account a wide range of tactics, from competitive analysis and content optimization to link building and landing page optimization. 
Regardless of their respective industries, businesses must embrace SEO as a must-have marketing strategy. And with so many brands fighting for the same spot on the first page of Google, getting there takes a lot of skill. Luckily, there are countless companies across the nation dedicated to helping businesses improve their online presence. Whether they serve fintech startups or nonprofits, these SEO experts have the skills needed to bring brands to the top of their SEO game.
