Benefits of SEO-First Strategy

Many of the businesses I work with face a common challenge: skyrocketing customer acquisition costs. When it comes to small businesses and start-ups, they also struggle with limited resources, which restricts their ability to balance both paid acquisition and organic website growth (mainly via SEO).

But the benefits of SEO-first strategy number far above relying primarily on paid acquisition.

Once you’ve got a solid strategy implemented on your website, gains for your growth continue to compound over time. Your website traffic and keyword rankings often improve without much additional lift or spend. That contrasts greatly with the paid acquisition model of Facebook and Google Ads, which require consistent or even increasing spend over time to see the same results.

But business owners and marketers alike often worry about what it will take to get started with SEO and maintain over time.

Search engine optimizations seems to require a great deal of technical knowledge when you’re first starting out.

And that’s why it’s important to identify the right tools to help minimize that lift.

As someone who often works with small businesses and start-ups, I’ve familiarized myself over time with the best free SEO tools available to help get the job done at minimal cost and with minimal lift.
