A full commercial SEO stack (rank tracker, crawler, keyword database, backlink index) runs somewhere between $3,000 and $9,000 a year at small-business tiers, and considerably more at scale. Agencies amortise those licences across dozens of clients. A single business cannot.
The good news is that the tools which produce the most decision-changing information are free, and two of them are strictly better than anything you can buy, because they contain your actual data rather than an estimate of it.
Here are twelve, in rough order of how much they will change what you do.
1. Google Search Console
The only tool that shows what Google actually thinks about your site. Everything else in the industry is inference.
The four reports that matter most:
- Performance → Queries, with your brand name filtered out. Set a query filter to “not containing” your brand. What remains is your real search visibility. For many sites, almost nothing remains, which is itself the finding.
- Performance sorted by impressions, checking CTR. Anything with high impressions and low click-through is a title problem, not a ranking problem. Thirty-minute fix.
- Indexing → Pages, and the “Not indexed” reasons. A page that is not indexed cannot rank regardless of how good it is. The reason codes each imply completely different work.
- URL Inspection → Test Live URL. Fetches the page as Googlebot right now and shows the rendered HTML. This is the definitive check for whether your JavaScript content is visible to search engines.
Free, already available for your domain, and almost entirely unread past the front-page graph.
2. Bing Webmaster Tools
Worth ten minutes of setup even though Bing traffic is negligible in most markets.
It imports your Search Console verification, then gives you a keyword research tool with actual search volumes at no cost, plus a site scan that catches technical issues, and backlink data that occasionally surfaces links Google’s report misses.
The volumes are Bing’s, not Google’s, so treat them as directional. For a business that cannot justify a keyword tool subscription, directional beats nothing.
3. Screaming Frog SEO Spider (free tier)
Crawls up to 500 URLs at no cost, which covers most small business sites entirely.
What to do with a crawl: find pages returning 404 or redirect chains, find duplicate and missing title tags, find pages with no internal links pointing at them, check click depth from the homepage, and export every internal link with its anchor text.
That last export is the one nobody runs. Sort it by anchor text and count how many links say “click here” or “read more”. Internal links are the only significant ranking signal under your complete control, and most sites waste them entirely.
4. PageSpeed Insights and the CrUX report
PageSpeed Insights gives you two things and people consistently read the wrong one.
The lab score at the top is a simulation run on Google’s hardware. It is a debugging tool.
The field data (Chrome User Experience Report, shown above it when available) is real measurement from real visitors on their real devices. That is what counts, and the two frequently disagree. A site scoring 95 in the lab can be failing in the field, especially where the audience skews toward mid-range Android hardware on congested mobile data.
Google’s own case studies show the stakes: Vodafone Italy gained 8% more sales from a 31% Largest Contentful Paint improvement, and Agrofy Market recorded a 76% reduction in load abandonment from a 70% LCP improvement.
5. Google Business Profile, and its insights panel
Free, and for a local business it is the highest-value asset you own.
Google displays a local pack in roughly 93% of local queries, and that pack takes about 42-44% of the clicks. Complete profiles receive seven times more clicks than incomplete ones, and 56% of profiles are not optimised.
The under-used part is the insights panel, which shows the actual search terms surfacing your profile. That is free keyword research based on real queries from real nearby customers, and almost nobody looks at it.
6. Google Trends
Not for absolute volume: the numbers are relative, not counts. Use it for three things it does better than any paid tool:
Seasonality. Pull a five-year view of your main term. If demand peaks in a particular window, content needs to be indexed and maturing three to six months earlier. Publishing in the month you want the business is publishing too late.
Direction. Is this term growing or dying? A keyword tool gives you last month’s volume. Trends tell you whether that number is on the way up or down.
Regional split. Where within your country is the demand? Useful for deciding which location pages are worth building.
7. Google Rich Results Test and the Schema Markup Validator
Structured data generates the rich results that make your listing visibly larger in search: star ratings, prices, FAQ expansions.
The Rich Results Test tells you which rich result types your page qualifies for. The Schema Markup Validator checks the syntax more broadly. Both free, both instant.
Standard warning: never fabricate structured data. Ratings and review counts must come from real stored submissions. Emitting an invented AggregateRating breaches Google’s structured data policy, risks a manual action on a site whose entire value is organic traffic, and in several jurisdictions is independently enforceable as a consumer protection matter.
8. Google Analytics 4
Imperfect, frequently disliked, and still the free answer to the one question that matters: which pages produce enquiries.
Configure conversion events for the things that are actually worth money: form submissions, calls, WhatsApp clicks, booking completions. Without that, every other tool on this list is telling you about traffic rather than about customers, and traffic is not the goal.
If you take one action from this article, make it this one. Most businesses cannot attribute a lead to a channel, which means every marketing decision they make is a guess.
9. Google Keyword Planner
Requires a Google Ads account. Does not require you to run ads.
The volumes are bucketed into ranges rather than exact figures unless you are spending, which is a real limitation. But it is the only free source of Google’s own volume data, and for validating whether a term has meaningful demand it is sufficient.
Pair it with the Search Console. Keyword Planner estimates what people search. Search Console counts what people searched to find you. The gap between the two is your opportunity list.
10. The search engine itself
The most under-used research tool available, and free in the most literal sense.
Search your target query and read the entire first page. What page type is ranking: a product page, a guide, a comparison, a listicle, a forum thread? If every result is a comparison and you built a service page, you have answered the wrong question and no amount of optimisation fixes that.
Read the People Also Ask box. Those are real queries with real demand, and they map directly onto the sections your page should contain.
Check site:yourdomain.com to see roughly what Google has indexed, and look for pages you forgot existed.
Search your own brand name and see what else appears: old profiles, duplicate listings, review sites, competitors bidding on your name.
11. Google Alerts, for the cheapest link monitoring there is
Set an alert for your brand name, your key executives’ names, and two or three of your most distinctive product terms.
What it surfaces: unlinked brand mentions, which are the highest-conversion outreach opportunity available. Someone has already written about you and simply did not link. A polite email converts these at a rate no cold outreach campaign matches, and the mention is genuinely editorial rather than manufactured.
It also catches people republishing your content, competitors using your brand name in their copy, and news coverage you would otherwise miss.
Free, takes two minutes to configure, and it is the only free tool on this list that generates links rather than diagnosing problems.
12. Your own analytics as a keyword source
The most under-used research asset is the site search box, if you have one.
Every query typed into your internal search is a customer telling you, in their own words, what they wanted and could not find. It is unfiltered demand data from people already on your site, and unlike any external tool it is specific to your business rather than estimated from a national index.
Configure site search tracking in GA4 and read the report monthly. Two things fall out: pages you should build because people keep looking for something you have not written, and vocabulary you should adopt because customers name things differently from how you do.
That vocabulary gap, between how a business describes itself and how customers search, is the single most common reason a site ranks for nothing but its own brand name. Your own search box hands you the customer half of it for free.
What the free stack cannot do
Three honest limits, because this list is not an argument that paid tools are pointless.
Historical rank tracking at scale. Search Console gives you sixteen months of query data, but not daily position tracking across hundreds of keywords. If you need that, you need to buy it.
Competitor intelligence. No free tool tells you what a competitor ranks for or who links to them. This is the single strongest argument for a paid subscription, and for many businesses it is the only one.
Comprehensive backlink data. Search Console shows links Google has attributed to you. It does not show a competitor’s profile, and it is incomplete even for your own.
And the largest gap: diagnosis. Tools produce data. Knowing which forty of the four hundred issues in a crawl actually matter for your site is knowledge, and no subscription supplies it. This is why the efficient purchase for a small business is usually a one-off audit with a prioritised list, executed in-house, rather than a monthly retainer that funds a handful of hours.
Businesses that hire seo expert support on that basis (buy the thinking, do the work yourself) consistently get more from a small budget than those who hand over the whole thing. The same applies when a build is involved: studios that handle both the site and the growth, like https://raiserank.com.np, tend to sequence the technical fixes before the traffic work, because sending visitors to a site that cannot convert them is a subsidy to your competitors.
The monthly routine
Thirty minutes, once a month, using only the free tools:
- Search Console → brand-filtered query report. Anything new?
- Search Console → high impressions, low CTR. Rewrite those titles.
- Search Console → indexing reasons. Anything newly excluded?
- PageSpeed Insights → field data on your two most important pages.
- Business Profile → new reviews responded to, insights panel skimmed for query ideas.
That is more useful than most retainers deliver, and it costs nothing but the half hour.
