SEO isn't dead, but SEO courses that teach keyword density should be

Last updated: October 2026 · Written by Adrian Prokopiec, founder of 20 Minute Marketing · 7 min read

The straight answer: My view, as founder of 20 Minute Marketing, is that SEO isn't dead, but any SEO course that still teaches keyword density should be retired. Google's own documentation treats excessive keyword repetition as spam, and Google's Search Advocate John Mueller has said keyword density isn't an SEO factor. Modern SEO teaching should cover search intent, helpful content, technical basics, entities and how to be cited in AI Overviews and answer engines. Keywords still matter for relevance. Ratios and formulas don't.

Every year someone declares SEO dead. Every year people still type questions into Google, and businesses that show up for those questions still win customers. SEO has changed a lot. It hasn't died.

What should die is a particular style of teaching it. You've probably seen it: "aim for a keyword density of 1 to 2 percent", "use your keyword in the first 100 words, twice in the H2s and once in the last sentence", "write exactly 1,500 words". It's tidy, it's easy to grade, and it teaches beginners to write for a formula instead of a person.

What Google actually says

This isn't my opinion against someone else's. Google has been unusually direct about it.

• Keyword stuffing is spam. Google Search Central's spam policies define keyword stuffing as "the practice of filling a web page with keywords or numbers in an attempt to manipulate rankings in Google Search results", and list "repeating the same words or phrases so often that it sounds unnatural" as an example.
• Repetition tires users. Google's SEO Starter Guide says excessively repeating the same words, even in variations, "is tiring for users, and keyword stuffing is against Google's spam policies". The same guide notes Google's language matching systems can understand how a page relates to many queries even without the exact terms.
• Density isn't a factor. When asked on Reddit in 2021 whether keyword density was still an SEO factor, Google Search Advocate John Mueller replied simply "No", as reported by Practical Ecommerce.
• No preferred word count. Google's guidance on creating helpful, reliable, people-first content asks whether you're writing to a particular word count because you've heard Google has a preferred one, and answers: "No, we don't."

When the search engine itself tells you a tactic isn't a factor and its spam policies describe the overuse of it, a course that teaches it as a core technique is out of date. Not slightly behind. Out of date.

What modern SEO teaching should cover instead

On that last row, Google's own guidance is reassuring for learners. Its page on AI features and your website says there are no additional requirements to appear in AI Overviews or AI Mode, and that the best practices for SEO remain relevant. In other words, good fundamentals are the AI strategy. The skill a course should add is writing clear, well-structured, quotable answers that both people and machines can lift and attribute.

A quick test to tell if an SEO course is outdated

Open the course outline or the free preview lessons and look for these. Give the course one point for each red flag.

• A keyword density percentage. Any number, any range.
• A fixed word count rule. "Every post must be at least X words to rank."
• The meta keywords tag taught as a ranking step.
• No mention of search intent. If the course never asks "what does the searcher want?", that's a gap.
• No mention of AI Overviews or answer engines. For a course sold in 2026, that's a sign it hasn't been updated in a while.
• Screenshots of tools or search results that look years old. Interfaces change, and a course that never re-records is a course nobody is maintaining.

My rule of thumb: one red flag might be a lesson that slipped through. Two or more and I'd keep looking. The general approach to comparing courses is in the honest comparison of SEO courses in Australia.

Where the other side has a point

Defenders of the old approach aren't entirely wrong, and I want to give them their due.

Keywords still matter for relevance. Google's own Starter Guide tells you to think about the words a user might search for to find your content, and notes that experts and beginners may use different terms. If your plumbing page never mentions "hot water system" and that's what your customers search for, you have a real problem. Keyword research is still one of the most useful skills a beginner can learn.

Formulas also have a teaching purpose. A beginner staring at a blank page can find "use the phrase in your title and first paragraph" genuinely helpful as a starting habit.

Where I'd draw the line is the ratio. Using the words your customers use is good practice. Counting how often you've used them and aiming for a percentage is not. The first teaches you to understand people. The second teaches you to write for a calculator, and Google has told us plainly it isn't reading that way.
