SEO myths last because they were once on a checklist, and checklists get copied. Some cost you nothing but time. Others make your pages harder to read, which is the opposite of what Google wants.
Here are 8 SEO myths we still see on small business sites in 2026. For each one: where it came from, what Google actually says, and what is still worth doing.
Why do SEO myths last so long?
Most started with a grain of truth. Long pages often ranked well, so people assumed length was the reason. Old tools scored pages on keyword counts, so people wrote for the score. Then the advice got repeated long after Google said otherwise.
The fix is simple. Check the claim against Google’s own documentation. Google Search Central publishes plain guidance on most of these, and we link to it below.
1. Do you need LSI keywords?
Where it came from: latent semantic indexing is an information retrieval method from a patent filed in 1988. SEO tools later borrowed the name for lists of “related keywords”.
What Google says: in July 2019, Google’s John Mueller said there is no such thing as LSI keywords, and that anyone saying otherwise is mistaken.
Still worth doing: cover the questions and words your customers naturally use. A post about a boat trip that mentions the pier, the weather, seasickness and what to wear is simply a complete answer. No special list needed.
2. Is there an ideal keyword density?
Where it came from: some old checklists, and a few plugins, scored pages on how often a phrase appeared. Figures like 2% did the rounds.
What Google says: there is no magic percentage. Google’s spam policies define keyword stuffing as filling a page with keywords to manipulate rankings. One of its examples is “repeating the same words or phrases so often that it sounds unnatural”. The SEO Starter Guide adds that repeating the same words over and over is tiring for users.
Still worth doing: use the words your customers actually search, in the title, the main heading and the first couple of lines. Then write naturally. Read it aloud. If you wince, so will your reader.
3. Do longer posts always rank better?
Where it came from: thorough pages are often long, so long posts looked like winners. Being thorough was what helped. Length was a side effect.
What Google says: the SEO Starter Guide says the length of content alone does not matter for ranking. The helpful content guide asks whether you are writing to a word count because you heard Google prefers one, then answers: no, it does not.
Still worth doing: some topics need depth. Write until the question is answered properly, then stop. Cut the 300 words of warm up before the answer.
4. Does Google use the meta keywords tag?
Where it came from: early search engines read it, so it went into every SEO checklist.
What Google says: the SEO Starter Guide says Google Search does not use the keywords meta tag. Google first said so in 2009. In the same post it said it does not use the meta description in ranking either.
Still worth doing: leave any meta keywords box empty. Spend the time on a clear meta description instead. It will not move rankings, but Google can use it as your snippet, and a good one earns the click.
5. Does bounce rate affect Google rankings?
Where it came from: bounce rate and time on site sit in your analytics, so it felt logical that Google would use them.
What Google says: in June 2020, John Mueller called the idea that Google looks at analytics bounce rate for ranking a misconception. To be fair to the idea, Google does say it uses aggregated and anonymised interaction data to assess whether results are relevant to a search. That is not your bounce rate figure.
Still worth doing: a bounce is not always bad. Someone searches your opening hours, reads them and leaves. Job done. But if most people leave a key page quickly, look for a real cause: slow loading, an unclear answer or no obvious next step. Fix it for people.
6. Do social shares improve rankings?
Where it came from: social signals featured on SEO checklists for years, and share buttons followed.
What Google says: in 2016, John Mueller said to use links to social media to add value to users, not in the hope that they improve rankings. In 2017, Gary Illyes said social helps because you market your content, not because search engines rank you better. In 2021, Mueller said Google does not use likes as a ranking factor.
Still worth doing: sharing is marketing, and it works. It puts your page in front of people who might buy from you, mention you or link to you. Check the preview card looks right when your link is shared.
7. Will duplicate content get you penalised?
Where it came from: people mixed up two different things. Having the same page at two addresses, and copying content to game search.
What Google says: the SEO Starter Guide says content available at more than one URL is fine and not worth fretting about. It is inefficient, but it will not cause a manual action. Deliberate tricks are a different matter. Google’s spam policies cover doorway pages, such as near identical town pages built only to rank.
Still worth doing: pick one main version of each page and link to that one. Give each location page real local detail rather than a swapped town name.
8. Do you need special files or schema for AI search?
Where it came from: AI Overviews and AI Mode are new, so new tricks followed: AI text files, special markup and “GEO” packages.
What Google says: there are no additional requirements to appear in AI Overviews or AI Mode. You do not need new machine readable files, AI text files or special schema. Google points to the same basics: crawlable pages, internal links, important content as text, and an up to date Business Profile.
Still worth doing: write clear answers near the top of the page. Our guide to local SEO and GEO covers how AI search is changing local results.

FAQ
Does Google penalise AI written content?
Not for being AI written. Google says appropriate use of AI is not against its guidelines. Using automation mainly to manipulate rankings is against its spam policies. Quality is what matters.
Is E-E-A-T a ranking factor?
Not on its own. Google’s SEO Starter Guide answers that question directly: no. Its helpful content guide says its systems look for signs of experience, expertise, authoritativeness and trust, with trust the most important.
How can I tell if SEO advice is out of date?
Look for a source. If advice cannot point to Google’s own documentation or a named Google statement, treat it with care. Then ask whether it helps a reader. If it only helps a score, skip it.
