Keyword stuffing is loading a page with the same word or phrase so many times that it reads unnaturally, and Google’s spam systems are built to catch it.
Keyword stuffing is a black hat SEO technique used in the hopes of improved keyword rankings in search engines. In essence, it was a way for sites to include a keyword (or keywords) on a page as many times as possible to seem more relevant to search engines, and as a result, rank higher in the search results.
This was a technique that worked for a time. In the early days of SEO, keyword stuffing allowed site owners to heavily influence search rankings whether their site was completely relevant or not.
Today, search engines have become much more advanced. Google now uses hundreds of different ranking signals and factors in its algorithm, including artificial intelligence. In fact, RankBrain (Google’s machine learning AI system) is the third-most important ranking factor in Google’s algorithm.
Google also runs a dedicated anti-spam AI system called SpamBrain, which it disclosed in 2022 after quietly using it since 2018 to catch spam patterns, including keyword stuffing, before pages are ever indexed.
This isn’t to say sites don’t still try to employ these methods to influence search rankings. Keyword stuffing is still a common tactic, even though it’s a black hat technique, and it can do real harm to your site’s performance.
What Are the Most Common Types of Keyword Stuffing?
Where It Hides | What It Looks Like | Quick Fix |
Title Tags | Every target keyword crammed into one tag, often past 60 characters | One clear, descriptive phrase, keyword included once |
Page Content | Text repeated past the point of sounding natural, chasing a density score | Write for the reader first, use the keyword where it fits |
Alt Tags | Strings of keyword variations instead of a real image description | Describe what’s actually in the image |
Meta Keywords | Every keyword variation the site wants to rank for | Leave the tag empty; Google stopped using it years ago |
Title Tags
Keep your title tag under 60 characters and built around one clear, descriptive phrase, not every keyword you want to rank for.
Keyword stuffing title tags is probably one of the most common forms of keyword stuffing.
And I get it – the DIY, self-taught SEOs are all told the same thing:
“Put keywords in your title tag! It’s the most important element for SEO!”
Don’t get me wrong, it’s important. But there’s definitely a limit to a good piece of advice. Here’s an example: I’m a sports junkie (in case you didn’t gather from my last Kobe Bryant-related blog post), and I frequent a reputable site for quick-hitting news and updates on major sports.
The home page title tag?
[SITE] Fantasy Football, Baseball, Basketball, and Hockey. Fantasy Football rankings, fantasy football news, fantasy cheat sheets, fantasy football sleepers and more.
For those of you counting, that’s 21 words and 166 characters.
And it’s not that the site doesn’t cover all of these topics. However, per Google’s own guidelines for webmasters, a title tag is ‘critical to giving users a quick insight into the content of a result and why it’s relevant to their query.’
In short, a good, well-written title tag should be a summation of the page which may or may not include a targeted keyword for the page. Remember – search engines can only display approximately 70 characters from your title tag, so it’s important to be as concise and descriptive as possible.
If you want to include your brand or site name in your title tag, you can do this, too. Google actually recommends branding your page titles, but separating your descriptive title and your brand name with a delimiter (hyphen, colon, pipe, etc.).
So rather than this:
[SITE] Fantasy Football, Baseball, Basketball, and Hockey. Fantasy Football rankings, fantasy football news, fantasy cheat sheets, fantasy football sleepers and more.
We can write a descriptive, summarized title tag of this:
[SITE] | Fantasy Sports News, Rankings & Resources

Page Content
There’s no magic keyword density percentage. Write naturally, and check readability, not just keyword counts.
This is the arguably the most thought-of method when it comes to keyword stuffing and it centers around the idea of keyword density.
Keyword density is the percentage of your page content using a keyword or phrase compared to the total amount of content. Keyword density used to be one of the most important ranking factors for search engines. The logic was simple: if a page used a keyword a certain number of times, it had to be relevant, right?
Enter, keyword stuffing.
In today’s SEO, keyword density is about finding the perfect balance of keyword-usage in a given piece of content. In fact, there are plenty of tools out there that will analyze your text and give you your keyword density score.
But is this really how we want to do SEO? Our content shouldn’t be about fitting in a keyword x amount of times in a 400-word piece of content. Content should flow naturally and be as useful to the reader as possible. A search engine’s entire goal is to serve up the most useful content – not the content with a keyword density score that matches a specific number.
For a deeper look at where that balance sits today, see our guide to keyword density and content optimization.
The same logic applies if you’re using AI tools to draft content. Repeating a phrase to hit a density target doesn’t fool Google’s spam systems, and it reads just as unnatural to a human audience.
Google’s spam policies were updated in March 2024 to specifically cover “scaled content abuse,” which includes pages where the content makes little sense to a human reader but is packed with search keywords, whether a person or an AI tool produced it.
For more on how AI search tools evaluate content quality, see our piece on optimizing for generative search.
A common version of this shows up on location pages for multi-location healthcare or financial services clients: a page that repeats “orthodontist in Springfield, IL” or “personal injury lawyer in Springfield, IL” seven or eight times to cover every ranking variation. Google’s algorithms read that as stuffing even when the intent was just to rank locally. One well-written page that mentions the service and the city naturally does the job without the repetition.
See our guide to optimizing ‘near me’ searches for more on getting local pages right.
Alt Tags
Write alt text that describes the image for someone who can’t see it. If it wouldn’t make sense read aloud, it’s not good alt text.
Alt tags, or alt attributes, are alternative text provided in the IMG <img> tag used to describe the content of the image. This does two things:
- It provides anyone using a screen reader – bad connection, visually-impaired visitors, etc. – with descriptive text of the image file.
- It aids Google and other search engines in being able to identify the content of the image itself. Although search engines have improved in their ability to identify an image without alt text, descriptive alt text can help to better identify these photos.
Alt text isn’t visible to the user, which makes alt tags a common culprit for keyword stuffing. If the end user never sees the alt text for an image, what harm can it do if I fill it with keywords?
However, Google openly states that keyword stuffing alt text is treated the same as any other form of spam. This means you should be creating alt text for its intended purposes.
Per Google’s image publishing guidelines, alt text should be ‘useful, information-rich content that uses keywords appropriately and in context.” To further optimize your images, your image file name should also be descriptive of your photo.
Here’s an example:
| Good Example | Bad Example |
Image file name | two-cats-sleeping.jpg | xyz123.jpg |
Image alt text | Two cats sleeping on top of a red blanket | cat, cats, two cats, two cats sleeping, two sleeping cats, sleeping cats, cats that are sleeping |

Meta Keywords
Skip meta keywords entirely. Google stopped using them for ranking over a decade ago, and filling them with variations only tips off competitors and spam filters.
Meta keyword tags are one of the many possible meta tags that can be inserted into your HTML.
A meta tag, in a nutshell, is a tag inserted into the HTML source used to describe a page or give directions to a search engine for a single page. There are several useful meta tags that are especially important to SEO (title tags, meta descriptions, meta robots, to name few), but meta keywords aren’t among them.
Meta keywords were once important to SEO but were overly abused by, you named it, keyword stuffing. Many sites included every variation of every targeted keyword in the hopes of better rankings. Google – and other search engines – caught on to this practice, and meta keywords essentially became obsolete.
However, keyword stuffing meta keywords can still harm your site in two ways:
- Search engines – including Bing and Yahoo – have previously stated meta keywords are used to identify spam, leading to possible site penalties if used incorrectly or inappropriately.
- Meta keywords essentially identify your keyword strategy to your competitors.
Because meta keywords can do much more harm than good to your site, it’s best to avoid them altogether – especially if you’re concerned about keyword stuffing or unwilling to share your targeted keywords with your competitors.
How Do You Audit Your Site for Keyword Stuffing?
Run a crawl of your site with a tool like Screaming Frog, then check title tags, body copy, alt text, and any leftover meta keywords tags for repetition that reads unnatural.
It’s incredibly important to make sure your site isn’t guilty of keyword stuffing, regardless of your intentions.
Screaming Frog SEO Spider, a popular web crawling tool, can be an incredibly powerful and efficient auditing tool. Screaming Frog will crawl the elements of your site and the internal code, allowing you to quickly audit these elements with little customization required.
Google Search Console is worth checking too. A sudden drop in impressions, or a manual action notice for “thin content with little or no added value,” is often the first sign a page has crossed the line.
Perform regular audits – using Screaming Frog or any other tool(s) you may prefer – to make sure your site is in line with best practices.

Frequently Asked Questions
Is keyword stuffing still against Google’s rules in 2026?
Yes. Google’s spam policies still list keyword stuffing by name, defined as repeating words or phrases, or listing cities, regions, or phone numbers, in a way that reads unnaturally and adds no real value for the reader.
What keyword density is safe to use?
There’s no official safe percentage. Google dropped keyword density as a ranking signal years ago. Write the phrase where it naturally fits and stop counting.
Can AI-written content get flagged for keyword stuffing?
Yes. Google’s scaled content abuse policy, introduced in 2024, covers pages where the content makes little sense to a human reader but is packed with search keywords, regardless of whether a person or an AI tool wrote it.
How do I check if my own site has keyword-stuffed pages?
Run a crawl with a tool like Screaming Frog and scan title tags, body copy, and alt text for repeated phrases. Google Search Console can also flag a sharp drop in impressions or a manual action tied to thin content.
What’s the difference between keyword stuffing and normal keyword use?
Normal keyword use puts the phrase where a reader would expect it, once or twice, in a sentence that still sounds natural. Keyword stuffing repeats it past that point to chase a search engine instead of serving the reader.
