Why should I prioritize Technical SEO?

It's about the laying the foundations

Technical SEO is a broad topic, but allowing Google to crawl and index a site is a big part of it. If a site can't be properly crawled and indexed, all your other SEO activities are useless. You can create the best content, and get as much links as you can, but your site still won't show up in Google. So before anything else, you need to make sure the technical foundations are solid.

There's usually some low hanging fruit

We often see technical SEO reports contain some sort of low hanging fruit: fixes that can be implemented at low cost, with lots of benefits. By finding and fixing some of these issues, you boost your website's visibilitywithout paying a high price.

It's a long-term strategy

Improvements you make to the technical state of your website are long-term improvements. It's unlikely that new hypes come up that require you to make more changes in 2 years. People want a fast website now, and they'll want it in 2 years time from now. So anything you do to make your website faster, keeps paying dividends in the long term. The same holds for crawl optimizations, security, and a proper website structure. Fix it ones, and it'll work for years to come.
