Every list of the best SEO tools seems to end with a dozen subscriptions you will never open. Here is the working version instead: the free tools that cover most businesses completely, the paid platforms that earn their fee once you are competing seriously, and the specific job each one does. It is the stack we use daily at SEO Soar, minus the ones we trialled and dropped. Spoiler: the best SEO tools for a small business are mostly free, and the expensive part was never the software anyway.
The free tools every website should have
Most best SEO tools round-ups bury these, because nobody earns a commission recommending free. These free SEO tools are not trials or teasers; in several cases they are the source data the paid platforms resell.
Google Search Console is the most important tool on this list, free or paid. It shows the actual searches you appear in, your average position, indexing problems and manual penalties, straight from Google. It also confirms Google can actually index your pages, the failure mode nobody notices until traffic flatlines. If you set up one thing this week, make it this one; our Search Console guide walks through it step by step.
PageSpeed Insights measures speed and Core Web Vitals the way Google measures them, including real-user Chrome data where your site has enough traffic. Run your money pages through it and fix what it flags before buying anything.
Google Trends shows demand over time: seasonality, rising terms and regional differences across Australia. Our guide on how to use Google Trends turns its charts into actual decisions.
Google Business Profile rounds out the free set for local businesses. It is rarely framed as an SEO tool, but for local searches it behaves like one: the profile you edit there is the listing competing in the map results, and its insights show how people actually found you.
Our own free SEO tools (no signup, no catch)
We build free SEO tools for the jobs owners actually ask us about. The AI Visibility Checker tests whether ChatGPT, Gemini and Google's AI Overviews mention your business, a question no mainstream platform answers well yet. The SEO ROI Calculator turns traffic and conversion assumptions into revenue estimates, useful before you commit a budget. The Google review link generator creates the direct link that makes asking for reviews painless. And the schema generator writes valid structured data without you touching code. All four run in the browser, free, no email wall. Together with Google's own, the free tier answers the questions that matter monthly: what am I ranking for, is the site fast, what is demand doing, and do the AI engines know I exist. A calm hour across those each month beats a subscription nobody opens.
The best SEO tools worth paying for
Semrush is the all-rounder: keyword research, rank tracking, competitor visibility, backlink data and site audits in one platform. Its Australian keyword database is the reason it is the SEO software we reach for first when scoping a campaign, and why it tops most best SEO tools round-ups. One caution from daily use: treat any keyword tool's volume numbers as directional rather than gospel, and cross-check before betting a campaign on them.
Ahrefs is the link specialist. Its backlink index is the field's reference point: see exactly who links to your competitors and not to you, which is a link-building plan writing itself. Its keyword tools are excellent too, so plenty of teams run Ahrefs alone and miss nothing.
Screaming Frog is a desktop crawler that reads your site the way Google does and surfaces broken links, duplicate titles, redirect chains and thin pages in minutes. The free version crawls up to 500 URLs, which covers most small sites entirely.
A note on pricing: all three publish current prices on their own sites, and they change often enough that any figure printed here would go stale. Expect a meaningful monthly cost for the first two, and start with their trials before committing; a fortnight inside either platform tells you whether you will open it weekly or never.
How to choose the best SEO tools for your stage
Solo operator or local business: the free stack above is genuinely complete, and the best SEO tools for you cost nothing. Growing site in a competitive niche: add one paid platform, not three, and learn it deeply; the keyword tools in Semrush and Ahrefs overlap heavily, so paying for both rank trackers is donating money. Agencies and in-house teams: that is where a full stack of SEO software earns its keep, because the cost spreads across many sites. The pattern to avoid is the common one: subscribing at the ambition stage, then paying for dashboards nobody reads.
A worked example: a local trades business belongs on the free stack entirely. A national ecommerce store fighting for competitive category terms justifies Semrush or Ahrefs from month one. An agency runs the lot, because the cost spreads across every client site. Same logic at every stage; only the questions change.
The one-line rule: buy tools when a specific question keeps going unanswered, not when a list like this one tells you to. Even the best SEO tools are only as useful as the next action you take in them.
Tools show the work; they don't do it
The best SEO tools in the world cannot write your pages, earn your links or decide your strategy. A crawler tells you a title tag is missing; the ranking comes from writing a good one. That gap between finding and fixing is where most DIY stacks stall, and it is the actual product of an agency. It is also why best SEO tools lists age well: the winners barely change, because the underlying work barely changes. If you would rather the findings arrived with the fixing attached, that is what we do, and the first conversation is free.
