Do I need an account to use the tools?

No. Every tool works without an account. You only need one if you want to keep a history of your checks.

Which SEO tool should I start with?

Start with the Meta Tags Analyzer and the PageSpeed Insights test on your homepage. They show the two problems we see most often on small business sites: unclear titles and descriptions, and slow loading on mobile.
