When people talk about SEO tools, the conversation usually turns to expensive monthly subscriptions pretty quickly. Ahrefs, Semrush, Moz — they’re powerful, no question. But before you spend a penny, there’s a suite of tools sitting right under your nose, built by Google itself, and every single one of them is completely free.
These aren’t stripped-back trial versions or limited freemium tiers. They’re the real deal — the same tools used by professional SEO agencies every day. Here’s a look at all eight, what each one does, how to use it as a small business, and where its limits lie.
1. Google Search Console
This shows you everything about rankings.
Find it: search.google.com/search-console
Google Search Console shows you exactly how your website is performing in Google’s search results. It tells you which pages are getting clicks, which keywords are bringing people in, and whether Google is having any trouble crawling and indexing your site. It also alerts you to technical issues like broken pages, mobile usability problems, and manual penalties. Think of it as a direct line of communication between your website and Google.
The main benefit: You can see precisely which search terms are driving traffic to your site and which pages Google is actually ranking. That alone shapes every content and SEO decision you make.
How a small business can use it: Check the Performance report monthly to see which keywords are getting impressions but low clicks. These are pages sitting on page one or two that could move up with a few improvements. Use the Coverage report to catch any pages Google can’t access. If you’ve recently updated a page, use the URL Inspection tool to ask Google to re-crawl it.
Limitations: Data is delayed by a few days and only goes back 16 months. The keyword data is sampled and rounded, so exact figures aren’t reliable for precise analysis. It also won’t tell you much about your competitors, as it only covers your own site.
2. Google Analytics
This is all about your website visitors.
Find it: analytics.google.com
While Search Console focuses on how people find you, Google Analytics takes over once they arrive. It tracks visitor behaviour on your site, including where people come from, which pages they spend time on, where they drop off, and whether they’re converting into enquiries or sales. The current version is called GA4 (Google Analytics 4), which replaced the older Universal Analytics in 2023.
The main benefit: It connects your SEO efforts to real business outcomes. You can see whether organic traffic is actually turning into leads, calls, or purchases, not just visits.
How a small business can use it: Set up conversion events for key actions such as contact form submissions, phone number clicks, or thank-you page visits. Then use the Traffic Acquisition report to see how much of that conversion activity is coming from organic search versus other channels. This tells you whether your SEO investment is actually working.
Limitations: GA4 has a steep learning curve compared to the old Universal Analytics, and many small business owners find it confusing to navigate. It also relies on cookies and consent, so with privacy tools and ad blockers increasingly common, some traffic goes untracked. Setting it up properly, especially conversion tracking, often requires developer help.
3. Google Keyword Planner
Find it: ads.google.com/home/tools/keyword-planner
Originally built for Google Ads, Keyword Planner is genuinely useful for SEO too. You can use it to discover what terms people are searching for in your industry, see estimated search volumes, and find related keyword ideas you might not have thought of. You need a Google Ads account to access it, but you don’t need to run any paid campaigns.
The main benefit: It gives you search volume data straight from Google, the same source that’s serving the results you’re trying to rank in. That makes it a reliable starting point for any keyword research.
How a small business can use it: Type in your core services and see what related terms come up. Look for keywords with decent search volume but phrased the way a real customer would search, which is often more specific than you’d expect. Use these to shape your service pages, blog topics, and on-page copy. If you’re targeting a specific area, filter results by location to get locally relevant data.
Limitations: Unless you’re actively running Google Ads with spend, you only get broad search volume ranges such as “100 to 1,000” rather than exact figures. The tool is primarily designed for paid search, so some of its suggestions lean toward commercial rather than informational. For deeper keyword research, most SEO professionals pair it with a dedicated tool.
4. Google Trends
Find it: trends.google.com
Google Trends shows you how interest in a search term changes over time and across different locations. You can compare multiple terms side by side, filter by country or region, and see related rising queries. It draws on Google’s full search data, making it one of the most accurate sources for understanding search behaviour over time.
The main benefit: It helps you time your content strategically and avoid investing effort in topics that are declining in interest. It also surfaces what’s trending before your competitors have caught on.
How a small business can use it: Use it to plan seasonal content. If searches for your service spike every autumn, start publishing relevant content six to eight weeks before that peak. Compare variations of the same keyword, for example “boiler repair” versus “boiler service”, to see which phrasing people actually use. Check the “Related queries” section for content ideas and long-tail keyword opportunities.
Limitations: Google Trends shows relative popularity, not actual search volumes, so you can’t use it to gauge how much traffic a keyword would bring. It’s better for spotting trends and patterns than for building a keyword list. Very niche or low-volume search terms often show no data at all.
5. Google Alerts
Find it: google.com/alerts
Google Alerts monitors the web for new mentions of any search term you choose and sends you an email when something new appears. You can set the frequency, choose the sources (news, blogs, web, and so on), and filter by language and region. It takes about two minutes to set up and runs quietly in the background.
The main benefit: It keeps you informed about your brand reputation and your industry without any ongoing effort. You’ll know when someone mentions your business online, for better or worse.
How a small business can use it: Set up alerts for your business name, your key services combined with your location, and your main competitors. When someone mentions your business without linking to your website, that’s a potential link-building opportunity. Reach out politely and ask if they’d consider adding a link. Monitor competitor alerts to stay aware of what they’re doing and what people are saying about them.
Limitations: Google Alerts misses a significant amount of online mentions, particularly from social media, forums, and behind-login pages. It’s inconsistent in what it picks up and can send irrelevant results if your alert terms are too broad. For serious brand monitoring, dedicated tools like Mention or Brand24 are more thorough, but as a free starting point, it’s still worth having running.
6. Google Business Profile
Find it: business.google.com
Your Google Business Profile is what appears in the map pack and local listings when someone searches for a service near them. It displays your business name, address, phone number, opening hours, photos, reviews, and more, directly in Google’s search results before anyone even clicks through to your website.
The main benefit: For local businesses, this is often the single highest-impact thing you can do for your online visibility. A well-optimised profile with strong reviews can generate enquiries directly from the search results page, without needing a high-ranking website at all.
How a small business can use it: Complete every section of your profile and don’t leave anything blank. Add high-quality photos of your work, premises, or team. Choose your business categories carefully, as these directly affect which searches you appear for. Post regular updates to show Google your profile is active. Most importantly, ask happy customers to leave a review and make sure you respond to every one, positive or negative.
Limitations: Google Business Profile only benefits businesses with a physical location or a defined service area. It’s not useful for purely online businesses. The profile is also hosted on Google’s platform, so you have limited control. Listings can occasionally be suspended or have their information edited by third parties, which requires time to resolve.
7. Google PageSpeed Insights
Find it: pagespeed.web.dev
PageSpeed Insights analyses your website and gives it a performance score out of 100, along with a detailed breakdown of what’s slowing it down. It measures Core Web Vitals, which are Google’s set of user experience metrics used as a ranking signal, and separates results for mobile and desktop. You just enter a URL and it runs the test instantly, with no account needed.
The main benefit: A slow website hurts both your rankings and your conversion rate. PageSpeed Insights tells you exactly what’s causing the problem and what to prioritise, so you’re not guessing and you’re not paying someone to audit what you can check yourself for free.
How a small business can use it: Run your homepage and your most important service pages through the tool. Focus on the mobile score, as Google primarily uses the mobile version of your site for ranking. Share the report with your web developer and ask them to address the high-priority items first. Common quick wins include compressing images, enabling browser caching, and removing unused plugins or scripts.
Limitations: The report can be technical and difficult to interpret without a development background. Scores can also vary between tests, which makes direct comparisons unreliable. It measures lab data alongside real-world data, and a good score doesn’t guarantee good rankings. It’s one factor among many.
8. Rich Results Test
Find it: search.google.com/test/rich-results
Rich results are the enhanced listings you sometimes see in Google’s search results, including star ratings, FAQs, how-to steps, and event details displayed directly in the results page before anyone clicks through. They’re enabled by structured data, which is code added to your website that helps Google understand what type of content a page contains. The Rich Results Test checks whether that code is present and working correctly.
The main benefit: Rich results make your listing stand out visually in a crowded results page and tend to generate higher click-through rates. If your competitors have star ratings and FAQs showing in their listings and yours doesn’t, you’re at a disadvantage even if you’re ranking in the same position.
How a small business can use it: Paste your URL into the tool and see which rich result types your site currently qualifies for. If you’re not seeing any, speak to your web developer or check whether your CMS has a structured data plugin that can add this automatically. WordPress users can look at Yoast or Rank Math, both of which handle this well. Common types worth pursuing for small businesses include reviews, FAQs, and local business schema.
Limitations: The tool only tests for eligibility. Passing the test doesn’t guarantee Google will actually show rich results for your page, as Google decides whether to display them based on its own criteria and this can change without notice. Adding structured data also typically requires developer involvement unless you’re using a plugin that handles it for you.
When it makes sense to invest in a paid tool
The free Google tools will take you a long way, but they do have a ceiling. They’re built to help you manage your own website, not to analyse your competitors, build backlink strategies, or carry out in-depth keyword research across multiple sites. If you’re at the point where SEO is a serious part of your growth plan, a paid tool fills those gaps quickly.
That said, you only need one. These platforms largely cover the same ground, and paying for two or three of them is rarely worth it for a small business. Pick the one that fits how you work and what you need most, and get to know it properly before considering anything else.
Here are the four tools most worth considering.
Semrush
Pricing: From $139.95 per month (Pro plan). A free account is available with limited daily usage.
Find it: semrush.com
Semrush is one of the most comprehensive SEO platforms available. It covers keyword research, competitor analysis, backlink auditing, site health checks, rank tracking, and content optimisation, all in one place. It also includes tools for PPC research and social media, which makes it appealing if you want a single platform for multiple aspects of your digital marketing.
The main benefit: The competitor research features are particularly strong. You can see which keywords your competitors are ranking for, where their backlinks are coming from, and how their traffic has changed over time. For a small business trying to understand why a local competitor is outranking you, this is invaluable.
Why a small business should consider it: If you’re working with an SEO agency or freelancer, there’s a good chance they already use Semrush and can share reports or access with you. It’s also worth considering if you want a single tool that handles keyword research, rank tracking, and site auditing without needing to switch between platforms.
Ahrefs
Pricing: From $129 per month (Lite plan). A limited free version called Ahrefs Webmaster Tools is available for your own site.
Find it: ahrefs.com
Ahrefs built its reputation on having one of the most accurate and frequently updated backlink databases in the industry. It has since expanded into a full SEO suite covering keyword research, content gap analysis, rank tracking, and site auditing. Many SEO professionals consider it the gold standard for link analysis and keyword difficulty scoring.
The main benefit: If backlinks are a priority for your SEO strategy, Ahrefs gives you more reliable and detailed link data than most competitors. Its keyword research tools are also highly regarded, particularly for finding content opportunities your competitors have missed.
Why a small business should consider it: Ahrefs is worth considering if you’re investing in content marketing and want to identify gaps in your coverage compared to competitors, or if you’re actively trying to build links and need to track progress accurately. The free Ahrefs Webmaster Tools plan is also worth setting up regardless, as it gives you useful site data at no cost.
Moz Pro
Pricing: From $99 per month (Starter plan). A 30-day free trial is available.
Find it: moz.com/pro
Moz Pro is often recommended as the most beginner-friendly of the major paid SEO tools. It covers keyword research, rank tracking, site auditing, and link analysis, with an interface and reporting style that’s easier to navigate than some of its competitors. Moz also developed the widely used Domain Authority metric, which gives a quick sense of a website’s overall strength in search.
The main benefit: The combination of a cleaner interface and strong educational resources makes Moz Pro a good choice for business owners who want to be more hands-on with their SEO without needing an agency to interpret the data for them.
Why a small business should consider it: If you’re managing your own SEO and find Semrush or Ahrefs overwhelming, Moz Pro is a more accessible entry point. The lower starting price also makes it easier to justify as a first paid tool investment.
Ubersuggest
Pricing: From $12 per month, or a one-off lifetime purchase from $120. A free tier with limited daily searches is available.
Find it: neilpatel.com/ubersuggest
Ubersuggest is the most affordable option on this list by some distance. Built by marketer Neil Patel, it covers keyword research, competitor analysis, backlink data, and site auditing at a price point that’s accessible for very small businesses or sole traders. It doesn’t have the depth or accuracy of Semrush or Ahrefs, but for businesses just starting to take SEO seriously, it provides a solid foundation.
The main benefit: The price. You get a meaningful set of SEO features for a fraction of what the bigger platforms charge, and the lifetime purchase option means you can avoid a recurring monthly subscription altogether.
Why a small business should consider it: If you’re not ready to commit to a higher monthly cost but want to go beyond what the free Google tools offer, Ubersuggest is a sensible starting point. It’s also a good option for business owners who want to get a feel for paid SEO tools before deciding whether to invest in a more advanced platform later.
Use free tools first before investing in professional SEO tools
You don’t need a large budget to build a solid foundation for your SEO. The eight free Google tools cover the most important bases:
- tracking performance,
- understanding your audience,
- researching keywords,
- fixing technical issues,
- and improving your local visibility, all without spending a thing.
If you reach the point where you want to go further, one paid tool is enough. Pick the one that matches your budget and how involved you want to be, and focus on using it consistently rather than collecting subscriptions you don’t have time to learn properly.
The businesses that get the most out of SEO aren’t always the ones with the biggest tool subscriptions. They’re the ones that consistently pay attention to the data they already have access to.
If you’d like help getting any of these set up or making sense of what they’re telling you, get in touch, we’re happy to help.
