SEO Tools for Freelancers and Small Websites — What Works Without a Monthly Bill (2026)

Last updated: March 2026

Search for "best SEO tools" and you'll get dozens of articles recommending Ahrefs, Semrush, and Moz. What those articles rarely mention is that the authors earn affiliate commissions on those recommendations, and that all three platforms cost upwards of $100 a month — over $1,200 a year before you've written a single word of content or fixed a single broken link.

If you're a freelancer managing a handful of client sites, or a small business owner handling your own SEO, that price point is hard to justify. You don't have an agency's volume of work, you don't have a team splitting the subscription, and you don't need the full feature set those platforms are built around.

This guide covers what actually works at the small end of the market. Not enterprise tools with a free tier that's too restricted to be genuinely useful — tools that are practical for someone managing one to five websites. I've included honest trade-offs for each one. And where one of my own tools is relevant, I'll say so directly rather than bury the conflict of interest in small print.

Crawling and auditing — finding what's broken

A site crawler visits every page on your website and checks each one for technical issues — broken links, missing titles, duplicate content, pages blocked from indexing, and more. This is the foundation of any serious audit. Without a crawler, you're guessing about what's wrong with your site.

Google Search Console is free, first-party, and essential — but it's not a crawler in the traditional sense. It shows data about pages that Google has already indexed, which means it doesn't catch pages that were never crawled, and it doesn't proactively scan your site for problems. Think of it as a monitoring tool rather than an audit tool. Use it regardless of what else you're running — it provides the most accurate picture of how Google actually sees your site.

Screaming Frog SEO Spider is the industry-standard desktop crawler. It's been around since 2010, it's used by professional SEO agencies worldwide, and the free tier crawls up to 500 URLs — enough for a small to medium site. The paid version is £199 per year. It's powerful and comprehensive, with a feature set that goes well beyond basic auditing. The trade-off is a complex interface that takes time to learn, and it's clearly aimed at professionals doing SEO full-time rather than freelancers doing occasional audits for clients.

Sitebulb is another desktop crawler with strong data visualisations and a cleaner interface than Screaming Frog. It's paid-only, starting around $150 per year. Worth knowing about if you want something more visual, but it's another annual subscription rather than a one-time cost.

Full disclosure — I'm the developer of Tom's Site Auditor, so factor that into how you weigh what follows. It's a Windows desktop crawler that runs entirely offline — no account, no cloud, nothing sent anywhere. It checks 30+ issue types across crawlability, titles, headings, links, images, and technical signals, and generates a self-contained HTML report you can open in any browser or share with a client. It costs $29 as a one-time purchase. The free trial crawls up to 10,000 pages with a 7 Day trial limit. The angle I built it for is the freelancer or small business owner who wants a crawler they own outright, not one they rent monthly. If that's your situation, it's worth trying against one of your sites. If you're doing deep technical SEO for large sites with complex architectures, Screaming Frog is the more capable tool.

Keyword research without paying $99/month

Keyword research tools vary enormously in what they offer and what they cost. The expensive end — Ahrefs, Semrush, Moz — provides comprehensive keyword databases, competitor gap analysis, and backlink data built for agencies doing this at scale. The free end gives you directional data that's genuinely useful for small sites if you understand its limitations. Here's what's worth using.

Google Search Console is again the starting point. The Performance report shows exactly which queries are already driving impressions and clicks to your site, broken down by page. This is real data from Google, not estimates — and it's free. The limitation is scope: it only shows queries where your site already has some presence. It won't help you discover new topics you haven't covered yet.

Google Keyword Planner requires a Google Ads account but you don't need to run ads or spend anything. It provides volume ranges and competition data. Outside of actively managing an ad campaign, the data appears in wide ranges rather than precise numbers, which limits its usefulness for organic keyword research. Still free, and it's Google's own data.

Keywords Everywhere is a browser extension that overlays volume, CPC, competition, and trend data onto Google search results and a range of other platforms. It operates on a pay-as-you-go credit system — $7 usd per month buys 100,000 credits, which covers a significant amount of research for a small site. It surfaces related keywords and question-based suggestions inline while you're doing normal research, which is a genuinely practical workflow. Tom's Site Auditor integrates with the Keywords Everywhere API — if you already have credits, you can pull volume and 12-month trend data for keywords extracted during a site scan without switching between tools.

AnswerThePublic generates question-based keyword ideas from Google and Bing autocomplete data. The free tier limits you to a small number of searches per day, but the output is useful for finding the questions people actually type — which is increasingly how content strategy should be approached. Good for generating blog post topics, FAQ content, and service page angles you might not have considered.

Ubersuggest has a free tier limited to three searches per day, which is restrictive but usable for occasional research on a single topic. Basic keyword metrics, related terms, content ideas. Fine for a quick check — not a substitute for a proper keyword tool if you're doing this regularly.

The keyword mining feature in Tom's Site Auditor takes a different approach from all of the above. Instead of starting from a search box, it extracts keywords and phrases already present in your site's content during a crawl — showing you what your site is already optimised for (or not). You can layer in volume data from Keywords Everywhere and track position changes over time. It's a different workflow from traditional keyword research, but useful for understanding your existing content footprint before deciding where to focus.

Getting Google to actually index your pages

Publishing a page doesn't guarantee Google will index it promptly. On newer sites, or sites that have added significant content in a short period, there can be a gap of days or weeks between publication and a page appearing in search results. A few tools help close that gap.

Google Search Console lets you request indexing for individual URLs directly, submit sitemaps, and monitor coverage — which pages are indexed, which are excluded, and why each exclusion happened. The URL Inspection tool is particularly useful: paste any URL and you'll see exactly how Google last crawled it and what it found. This is the primary tool for indexing management and there's no substitute for it.

Bing Webmaster Tools is significantly underused. It has its own URL submission, sitemap management, and a set of SEO reports that are often more readable than their Google equivalents. Bing drives non-trivial traffic in certain markets and demographics, and setting up Webmaster Tools takes about fifteen minutes. It's completely free and there's no good reason not to have it configured alongside Search Console.

IndexNow is an open protocol that lets you notify search engines immediately when a page is published or updated, rather than waiting for the next scheduled crawl. Bing, Yandex, and a growing number of engines support it. Tom's IndexNow Submitter is a free Windows tool that handles this — paste your URLs, hit submit, done. It doesn't cover Google (which doesn't participate in IndexNow), but for Bing and other participating engines it's the fastest way to get new content noticed.

Tracking what's working

Once you've fixed technical issues and published content, you need to know whether any of it is working. For small sites, two tools cover almost everything that matters.

Google Analytics 4 is the standard. It's free and tracks user behaviour in detail — where visitors come from, which pages they visit, how long they stay, what actions they take. The trade-off is a steep learning curve. GA4 was a significant departure from Universal Analytics and the interface remains genuinely unintuitive for newcomers. It's worth investing the time because nothing else provides this level of behavioural data for free. That said, don't let the complexity of GA4 put you off setting up Search Console, which is simpler and often more immediately actionable.

Google Search Console — again. The Performance report is often more useful than GA4 for organic search work specifically. It tells you which queries show your pages in results, which pages are getting clicks, and what your average position is for specific keywords. For a small site where most traffic comes from organic search, this is where you'll find the most actionable data. If you only have time to set up one tool, make it Search Console.

Bing Webmaster Tools provides an additional analytics layer for Bing traffic and presents keyword data in a more straightforward format than Google's. Since you've set it up for indexing anyway, checking the reports costs nothing.

Content tools that don't require a subscription

A handful of free tools for content quality and technical correctness are worth bookmarking. None of them require an account or ongoing payment.

Hemingway Editor (hemingwayapp.com) checks readability. It flags complex sentences, passive voice, and adverb overuse. Useful for service page copy and blog content where plain language matters. The browser version is free; there's an optional paid desktop app.

Google's Rich Results Test (search.google.com/test/rich-results) validates structured data markup. If you're using Schema.org for reviews, FAQs, products, or other rich result types, this tool confirms Google can read it correctly and previews how it appears in search results.

PageSpeed Insights (pagespeed.web.dev) gives you Core Web Vitals scores and specific, prioritised recommendations for any public URL. Check your homepage and your most important landing pages. The "opportunities" section tells you what to fix and roughly how much improvement each fix is expected to deliver — which makes it easy to prioritise.

Google's Mobile-Friendly Test confirms your pages render correctly on mobile devices. Most modern CMS themes pass without issue, but if you're running a custom or older theme, this is worth verifying before assuming everything is fine.

The realistic minimum toolkit

For a freelancer managing one to five small websites, here's the setup that covers the essentials without a recurring bill.

Start with Google Search Console — free, essential, the single most important tool on this list. Add Bing Webmaster Tools at the same time; it takes fifteen minutes and gives you a second data source at no cost. For site crawling, the Screaming Frog free tier handles sites up to 500 pages with no payment required. If you prefer an offline-first tool with a simpler HTML report format, the Tom's Site Auditor free trial crawls up to 10,000 pages with a 7 Day Trial limit — enough for a complete audit of most small sites. For keyword volume data, a Keywords Everywhere credit pack gives you a lot of coverage for $10. Round it out with Google Analytics 4 for behavioural data.

Total ongoing cost: zero to $10 per year, depending on how much keyword research you do. That's a significant difference from the $1,200+ that Ahrefs or Semrush would cost annually.

If your needs grow — larger sites, more clients, deeper competitor analysis, backlink data — that's when the paid platforms start to make sense. But for most small websites, the tools above cover auditing, keyword research, indexing, and analytics. The remaining work is writing useful content and earning links from other sites, and no tool can do that part for you.
