Best SEO tools for early-stage startups in 2026
By Roshan, founder of SearchMaxx - - updated - 7 min read
Most early-stage startups need four free tools and, at most, one paid one. Set up Google Search Console, Bing Webmaster Tools, PageSpeed Insights and the Rich Results Test first. Pay for Ahrefs, Semrush or SE Ranking only once someone will spend a few hours a week on keyword and competitor research.
Every price and limit below comes from the vendor's own pages, as of October 2026. We have not run a side-by-side data test of the paid tools, so we compare what the vendors publish.
The short list
| Tool | Cost, as of October 2026 | What it tells you | Do you need it at seed stage? |
|---|---|---|---|
| Google Search Console | Free | Which searches show your pages, and which pages Google has not indexed | Yes |
| Bing Webmaster Tools | Free | The same for Bing, plus how often Copilot cites your pages | Yes |
| PageSpeed Insights | Free | Whether real visitors get a fast page | Yes |
| Rich Results Test | Free | Whether your structured data works | Yes, after each schema change |
| Ahrefs Free | Free | Your own backlinks and keywords, plus a site audit | Yes |
| Screaming Frog SEO Spider | Free up to 500 URLs, or $279 a year | Broken links, missing titles, redirects | The free version covers most startup sites |
| Ahrefs | $29 to $449 a month | Competitor keywords and backlinks | When you start publishing content |
| Semrush | Free plan, then $139 to $299 a month | Competitor keywords and backlinks, plus AI visibility reports | When you start publishing content |
| SE Ranking | $129 or $279 a month | Competitor keywords and backlinks, plus AI prompt tracking | When you start publishing content |
| Moz Pro | $49 to $299 a month | Rank tracking and links, with low keyword limits on cheaper plans | Rarely the first pick |
Free tools to set up this week
Google Search Console
Google describes Search Console as "a free service" for monitoring and fixing your site's presence in Google Search (Google). It shows the searches your pages appear for, with impressions and clicks by query, page and country. The URL Inspection tool shows whether a page is indexed and lets you ask Google to crawl it. The Page indexing report lists pages Google excluded and why (Google).
It also covers AI search, but you cannot separate it. Google says pages that appear in AI Overviews and AI Mode "are included in the overall search traffic" and are reported under the "Web" search type (Google). There is no AI Overviews filter.
Downsides: it only shows your own verified sites. It tells you nothing about competitors.
Bing Webmaster Tools
Set this up even if nobody you know uses Bing. In February 2026 Microsoft added an AI Performance report in public preview. It shows how often your pages are cited as sources in Microsoft Copilot, in AI-generated summaries in Bing, and in some partner integrations. You get total citations, the average number of your pages cited each day, citation counts per page, and a sample of "grounding queries", the phrases the AI used to find your content (Bing). That is citation data from an AI engine itself, not an estimate from a third party.
You can import your verified sites from Search Console instead of verifying them again (Bing). Bing also includes keyword research, backlinks for any site, and IndexNow for telling search engines when a page changes (Bing).
Downsides: Bing says the AI metrics show how often you are cited, not your ranking or placement in the answer. The launch post does not mention click data.
PageSpeed Insights
PageSpeed Insights reports two things. Field data comes from real Chrome users over the previous 28 days. Lab data comes from a simulated load in Lighthouse. A page passes Core Web Vitals when the 75th percentile of all three metrics is good: Largest Contentful Paint at 2,500 ms or less, Interaction to Next Paint at 200 ms or less, and Cumulative Layout Shift at 0.1 or less (Google).
Downsides: the lab score moves between runs, and Google says lab data may miss real-world bottlenecks. Judge by the field data when you have it.
Rich Results Test
The Rich Results Test checks whether your structured data is valid and which rich result types it qualifies for. You can test a live URL or paste code. It reads JSON-LD, RDFa and Microdata, and it supports the Software app type that most software companies should use (Google).
Downsides: it only covers Google's rich result types. It fetches the page as Google-InspectionTool, so a robots.txt rule can block the test.
Ahrefs Free
Ahrefs Webmaster Tools was renamed Ahrefs Free. It has no time limit and needs no credit card. For your verified sites you get Site Explorer with up to 1,000 backlinks and keywords visible at once, Site Audit with 5,000 crawl credits a month per project, and a privacy-focused web analytics tool with up to 1 million events per project (Ahrefs).
Downsides: you cannot look up competitors. Ahrefs says competitor analysis of unverified sites needs a paid plan (Ahrefs).
Screaming Frog SEO Spider
A desktop crawler that finds broken links, redirects, missing titles and duplicate pages. The free version crawls up to 500 URLs. A paid licence costs $279 a year per user and removes the limit. It adds JavaScript rendering, scheduled crawls, structured data validation, and Search Console and PageSpeed Insights integrations (Screaming Frog).
Downsides: it runs on your own computer, and the output is a long table you have to interpret. The free version does not render JavaScript, so it will not show you what a browser sees on a client-rendered site.
Paid tools, and when they pay off
Buy a paid suite when you are about to publish pages aimed at specific searches and need to know what people search for and who already ranks. Until then, the free tools cover your own site. For a deeper look, see Ahrefs vs Semrush vs Moz and Ahrefs alternatives.
Ahrefs
The Starter plan costs $29 a month. It includes 200 credits a month, 1 month of history, 250 rows per report and 50 tracked keywords. It renews monthly only, and you cannot add users (Ahrefs help). Lite costs $129 a month for 5 projects, 750 tracked keywords, 1,000 credits per user and 6 months of history. Standard costs $249 with unlimited credits and 2 years of history (Ahrefs). Ahrefs reports 29 billion keywords in its index (Ahrefs).
Downsides: credits go fast. Opening a report costs 1 credit, and so does each new filter or date change (Ahrefs help). AI visibility tracking through Brand Radar AI is an add-on from $199 a month.
Semrush
Semrush has a free plan with 1 demo project and 10 reports a day. The SEO plan costs $139 a month, or $117.33 a month billed yearly. It covers 5 websites, 500 tracked keywords and AI visibility reports for any domain. The Starter plan, $199 a month, adds 50 AI prompts tracked daily (Semrush). Semrush reports 28.8 billion keywords across 142 country databases (Semrush).
Downsides: Semrush describes the SEO plan's research tools as "basic". Extra users start at $45 a month each.
SE Ranking
SE Ranking's cheaper plan costs $129 a month, or $103.20 billed yearly. It includes 10 projects, 2,000 tracked keywords, 100 AI prompts tracked daily, and keyword, competitor and backlink research with no listed cap. The trial lasts 14 days and needs no credit card (SE Ranking).
Downsides: one seat and 6 months of history on that plan. SE Ranking does not publish database sizes on its pricing page, so compare its numbers for your own competitors during the trial.
Moz Pro
Moz has a $49 plan for one website. Standard costs $99 a month for 3 sites, 300 tracked keywords, 150 tracked AI prompts and weekly prompt tracking across GPT, Gemini, Google AI Mode and Perplexity (Moz).
Downsides: Standard allows 150 keyword queries a month. That runs out in one research session.
What you can skip
- A separate rank tracker. Average position in Search Console is enough until you track dozens of target searches.
- Backlink tools before you have links. Ahrefs Free and Bing show the few you have.
- A suite for someone who logs in once a month. Use the free plans, or pay for one month when you plan content, then cancel.
- AI visibility tracking before you are indexed. Google says a page must be indexed to appear in AI Overviews or AI Mode. Fix indexing first.
A two-hour setup checklist
- Verify your domain in Search Console and submit your sitemap.
- Import the site into Bing Webmaster Tools.
- Run PageSpeed Insights on your home page and pricing page.
- Run the Rich Results Test on your home page.
- Create an Ahrefs Free account and run a site audit.
- If your site has under 500 URLs, crawl it with the free Screaming Frog.
- Check that AI search crawlers can reach you. Our guide to AI crawlers in robots.txt has a file you can copy.
None of these tools tells you whether ChatGPT, Claude or Perplexity can read your pages in the first place. Our free check tests that in about 10 seconds.
