Free & Paid SEO Tools for Monitoring Website Performance

Tracking how your website performs isn’t optional — it’s fundamental if you want to improve visibility, user experience, and growth over time. With the right tools, you can uncover technical issues, see what’s driving traffic, monitor keyword performance, and track the results of your optimisation efforts.

Below, I share the tools I use most — both free and paid — based on real experience working with SEO and digital marketing performance.

Free Tools (Essential for Every Website)

These tools are available at no cost and are the foundation of any performance monitoring strategy.

Google Search Console (GSC)

Google Search Console gives you insight into how your site is performing in Google search results. It shows your search impressions, average position, click-through rate (CTR) and indexing status, and it alerts you to technical issues that could impact performance.

This is a must-have for anyone focused on improving organic visibility.

Google Analytics 4 (GA4)

GA4 tracks user engagement, conversions, traffic sources and user behaviour. While its interface takes some getting used to, it provides the data you need to understand how visitors use your site — and what’s working (or not).

GA4 and GSC together give you a clearer picture of both search performance and user experience.

Ahrefs Webmaster Tools (Free)

Ahrefs offers a free version of its platform through Webmaster Tools once you verify your site. This includes a basic SEO site audit, organic keyword data and backlink information.

It’s not as comprehensive as the paid suite, but it’s one of the better free options for technical and SEO monitoring.

Paid Tools (Advanced Monitoring & Insights)

When you’re ready to dig deeper, these paid tools are incredibly useful for tracking ongoing performance and growth.

1) Ahrefs (Paid)

Ahrefs is my go-to paid tool for SEO and performance tracking. It’s reliable, constantly updated and packed with features that help you monitor keyword movements, assess backlinks, audit your site, and research competitors.

Why I use it:

  • Strong backlink index and insights
  • Accurate keyword tracking
  • Detailed site audits
  • Continual feature development

Ahrefs remains one of the most powerful platforms for ongoing SEO work.

2) Sitechecker

Sitechecker is a favourite — especially for small to mid-sized businesses focused on local performance and basic site health tracking. It’s affordable, easy to set up, and provides clear site audit reports.

Why I like it:

  • Good local keyword tracking
  • Strong technical site audit output
  • Visual dashboards that are easy to interpret

It’s not as feature-rich as some other platforms, but it does excellent job monitoring performance and issues without overwhelming complexity.

3) Semrush

Semrush is a long-standing all-in-one SEO and digital marketing platform. It includes keyword tools, competitive analysis, site audits and more.

Historically, it’s been one of the big players. After its recent acquisition, its future development path is less predictable, but it still offers a comprehensive toolkit.

Good for:

  • Competitive research
  • Keyword and market analytics
  • SEO + content strategy

It’s not always the most intuitive, but its breadth is useful when you want insight across different marketing channels.

Which Tools Should You Use?

There isn’t a “one-size-fits-all” answer — but here’s a practical approach I recommend:

Start with free tools:

  • Google Search Console
  • Google Analytics 4
  • Ahrefs Webmaster Tools

These give you visibility into both search performance and user behaviour without any upfront cost.

Once you need deeper insights or ongoing monitoring:

  • Ahrefs for advanced SEO and backlink tracking
  • Sitechecker for affordable site health and local keyword tracking
  • Semrush when you want broader competitive and keyword data

Each tool adds value in different ways — but together they provide a strong framework for tracking and improving your website’s performance.

Final Thoughts

Website performance monitoring isn’t a one-time task — it’s an ongoing process. Having the right tools in place means you can identify issues early, measure improvement and make informed decisions that support long-term growth.If you need help choosing the right tools or setting them up properly, I’m here to help — just get in touch.
