If you run a website, you’ve probably heard that “SEO tools” can help you get more traffic, improve visibility on Google, and fix problems on your site. But with so many tools out there, it can feel confusing knowing which ones you actually need, or what they even do.

This guide breaks down the most popular SEO tools in plain English. No jargon, no technical talk, just clear explanations of what each tool is good at, what it’s not, and when you should use it.

What Each Tool Does Best

Below is a simple summary of the most common SEO tools and where they shine.

1. Screaming Frog SEO Spider

Cons: Looks technical and can feel overwhelming at first

8. Lighthouse

Best for: Quick performance and quality audits
Why it’s useful: Built into Chrome, tests performance, accessibility, SEO, and more in a single click.

Why it’s useful: Offers the most accurate and flexible speed tests (location, device, connection speed, etc.).
Pros: Extremely detailed

As your website grows, you can add more tools if you need them. The important thing is to take action: check your site’s health, understand your visitors, and make improvements step by step.
