Free SEO tools FAQ: 13 questions people ask, answered

The 5 best SEO tools for most sites are free, and four of them come from Google and Microsoft, so their numbers are recorded rather than estimated.

Paid suites such as Ahrefs and Semrush add backlink data and competitor estimates, which helps once the free tools stop answering your questions. Just remember that they estimate, and the consoles record.

The best free tools for keyword research in SEO start with your own data: Search Console's Performance report lists the searches you already appear for, and those are the easiest keywords to win.

Google Keyword Planner adds monthly search volumes for new ideas. Google itself is the third tool: type a phrase and read the autocomplete suggestions, the People Also Ask questions and the related searches at the bottom of the page.

Our free People Also Ask tool collects those questions for two or three phrases at once and keeps the ones closest to a purchase. Then the keyword rank checker, free with a Google sign-in, shows where your site ranks in Google's top 30 for every variation of a phrase.

You can research keywords for SEO in four steps, and every step works with free tools:

1. Start with the searches you already rank for. In Search Console, open Performance, sort the queries by impressions, and look at positions 8 to 20: they are the closest to page one.
2. Expand each topic. Type it into Google and note the autocomplete suggestions, the People Also Ask questions and the related searches, then get their volumes from Keyword Planner.
3. Check the intent. Search each keyword and look at what ranks. If the top ten are product pages, a blog post won't rank, and the reverse is true too.
4. Give each group of keywords one page, and put its main phrase in the title, the H1 and the first sentence.

You can do SEO yourself for free, because most of the work costs time rather than money.

Search engines rank pages on two things, Authority and Relevance: a page that matches what the searcher wants, and links and mentions that show other sites trust it.

Writing that page, fixing its title and headings, getting it indexed and asking for links all cost nothing but hours. What money buys is speed: data at scale, a writer, or an agency's time.

A good first week: connect Search Console and Bing Webmaster Tools, find the pages sitting just off page one, and improve those before you write anything new. Our AI visibility audit adds the free checks for AI search in seven steps.

SEO is free in the way that matters most: Google and Bing never charge for organic rankings, and a click on an organic result costs you nothing.

The paid part is the work. You pay with your own time, a writer, an agency or tools, so the cheapest SEO is the kind you do yourself with free tools. Search ads are a different product: the sponsored results above and below the organic ones, billed per click.

ChatGPT can do parts of SEO well: drafting titles and meta descriptions, outlining a page, writing schema markup, explaining a Search Console error, or turning a list of questions into a FAQ.

It can't do the parts that need data it doesn't have. It doesn't see your Search Console numbers, it can't tell you where you rank today, and it doesn't know which sites link to yours, so treat any keyword volumes or rankings it gives you as guesses.

Google's line on AI-written pages is that it cares how helpful content is, not how it was made. Mass-producing pages to manipulate rankings breaks its spam policies either way.

ChatGPT is also a searcher in its own right. With web search on, it rewrites your question into its own searches and cites pages from the results, mostly through Bing and other search providers.

SEO is not dead now with AI, because the AI assistants search before they answer.

When we sent 100 everyday prompts to ChatGPT, Claude and Gemini on October 7, 2026, ChatGPT ran 216 web searches and cited pages from the results, and Gemini searched Google on 54 of the 100 prompts (our fan-out study has every search).

The pages they cite are pages that ranked for those searches. So the work that gets a page ranked is the work that gets it cited, and AI isn't replacing SEO so much as running it on your behalf.

What changed is the search itself. ChatGPT never once searched a prompt word for word, so the useful question is what it searched instead. Our free query fan-out tool shows those searches for your own prompt, and where your site ranks on Google for each one.

SEO with AI is usually called GEO, short for generative engine optimization, a name that comes from a 2023 research paper of the same title.

You'll also see AEO (answer engine optimization), LLMO and AI SEO.

All of them describe the same goal: being found, cited and described correctly in AI answers. In practice GEO is SEO plus a few checks classic tools don't run: can AI crawlers reach the page, which searches do the assistants run, and what do they say about your brand. Our guide to the best GEO tools matches the tools to each of those jobs.

Nothing is replacing SEO so far.

What is changing is where search results show up: a searcher who used to click a blue link may now read an AI Overview, or ask ChatGPT, which runs the searches and sums up the pages for them.

That can cost clicks, especially on questions with a short answer. But the answer still comes from pages a search engine found, indexed and ranked, so ranking still decides who gets cited.

You can measure the change instead of guessing. Search Console and Bing Webmaster Tools both report AI appearances now, and our AI performance report puts the two side by side, page by page.

SEO is still a thing in 2026, and it will still exist in 5 years for as long as people and AI assistants look things up in a search index.

Google's AI Overviews and AI Mode are built on Google's own index, and all three assistants in our study searched the web to answer.

The job is changing at the edges. Brand mentions matter more, so do the AI crawlers that need to reach your pages, and so do the searches the assistants actually run. But the core of SEO, a relevant page with enough authority to rank, is what every one of those systems still rewards.

Google's guidelines for SEO are called Google Search Essentials, and they come in three parts:

• Technical requirements: Googlebot can reach the page, the page works, and it has content Google can index.
• Spam policies: the practices that can get a page demoted or removed, such as keyword stuffing, link schemes and scaled content abuse.
• Key best practices: helpful content written for people, the words people search for in your titles and headings, and links Google can crawl.

The same rules cover Google's AI features. Its guide to AI features and your website says there is nothing extra to do to appear in AI Overviews or AI Mode beyond normal SEO best practices.

SEO is not difficult to learn at the level most sites need.

A few weeks with Google's free SEO Starter Guide and your own Search Console data will teach you titles, headings, internal links and indexing.

It gets harder in two places. Links take judgment, because the wrong ones break Google's spam policies, and they take time to earn. Technical SEO on large or JavaScript-heavy sites usually needs a developer.

The fastest way to learn is on a real site: pick one page, check where it ranks, improve it, and watch Search Console for the change over the next few weeks.
