When you think of Search Engine Optimization — or SEO, for short — one company probably springs to mind: Google.
That’s no surprise. For some time SEO has revolved around the world’s most popular search engine, which was launched in 1998—but it wasn’t always this way. The first search engine, Archie (short for “archive”) was launched in 1990. While Archie was groundbreaking, it was soon overtaken by bigger brands.
Let’s go beyond Google to understand the evolution of the search engine over the past few decades, and see what its future has in store!

Will SEO still exist in the future? Sure, guidelines may shift, ranking factors may change, and AI trends may advance, but as long as people search for stuff online, SEO must always play a pivotal role in your marketing strategy.
Whatever the future of SEO looks like, we recommend the following best practices for 2024 and beyond:

The Bottom Line
SEO has changed dramatically over the years, and it will continue to evolve in the future. One thing is certain—we must always provide relevant, high-quality content and a great user experience.
Doing right by your customers is not a strategy or tactic; it’s just good business. Some things change (like our embarrassing AIM handle *shudder*), but over-delivering for people never will.
