Running a business is hard enough without search feeling like a black box. The good news: a serious chunk of effective SEO, and increasingly, AI visibility, can be done with free or low-cost tools. The trick is choosing the ones that match your goals rather than collecting subscriptions you never open.
Here are the tools worth knowing, grouped by what they actually help you do.
Google gives away the foundations:
There is a paid tier, Google Analytics 360, but it starts around $50,000 a year and is built for enterprise. Almost no growing business needs it.
Semrush's Keyword Magic Tool makes it far easier to surface traffic-driving terms and understand intent, a core part of any strong search strategy. Full access starts at $139.95/month, though the free tier is enough to get started.
SERPWatcher from Mangools gives real-time updates on where your site appears in results, a simple way to keep an eye on your key metrics. It starts at $29.90/month. For the bigger picture of which metrics matter, see our guide to board-level SEO reporting.
Screaming Frog is a powerful crawler for spotting technical issues, broken links, redirect chains, missing metadata, and more. The free version crawls up to 500 URLs; the paid licence starts at £199/year. It is a great starting point, though it only sees part of the picture, as most standard audits miss around 60% of what now drives growth.
Ahrefs Backlink Checker lets you track and analyse the links pointing to your site. The free tool gives limited data; full access starts at $129/month. Use it to keep your link profile clean and relevant.
Yoast SEO is a go-to plugin for WordPress, with a free real-time content analysis tool and a premium plan at $99/year. Strong alternatives include:
These tools are excellent for traditional SEO, but none of them tell you how you appear inside AI answer engines like ChatGPT, Perplexity, and Google's AI Overviews, which is where a growing share of decisions now happen. Tracking AI citation rates and brand mentions across AI engines is a newer discipline most off-the-shelf tools simply don't cover yet.
SEO doesn't have to be expensive to start. But knowing where you actually stand, across both traditional search and AI, is the fastest way to spend your effort well. Run our free AI Visibility Checker to see how your site and brand are performing across every search surface, then get in touch if you'd like a hand acting on it.
