How Many Ads Can You Safely Put on Your Blog

If you regularly browse the web with no ad blocking software installed, I would venture to guess that you have come across a website that looks something like this. A page with a busy background - one that could have been an ad itself - and with sidebar ads, ads across the top above and below the navigation, ads along a gutter to the side of the content, ads within the content.

When you look at a page like that, what do you see? Where is the content? You see a headline. But there’s no page content above the fold. If you’re lucky, you might get a paragraph or two.

That is obviously the wrong way for things to be - it’s far too many ads and it hurts the user experience. Sites like that are why I installed my first ad blocker years ago and have never looked back.

It’s even worse on the mobile web. You have invasive ads that open tabs that are hard to leave or close, and it just destroys the user experience. Even otherwise good sites can have bad ads, and it makes users not want to use your site at all.

Having too many ads is a problem. Google has evolved its rules over the years. Their Page Layout Algorithm, launched back in 2012, began impacting rankings for sites with too many above-the-fold ads. Then in 2018, the Page Speed Algorithm started lowering rankings for sites whose load times were being dragged down by excessive ad weight. Google’s “Valuable Inventory” criteria now guides publishers on acceptable ad usage, and they have long since removed the old hard cap of 3 AdSense ads per page.

Under the latest rules, each page can have more than one large ad unit (greater than 300×600), and mobile pages allow an unlimited number of 320×100 ad units below the fold. However, mobile pages are still limited to just 1 ad above the fold - a rule worth noting.

The fact is that there’s no single fixed number of ads that can universally be labeled “too many.” A site can have sidebar ads, a slide-in ad, in-text ads, and a banner across the footer and still be clean in design. The content can be front-loaded and tasteful, without getting in the way of the user experience.

At the same time, all it takes is an overly large or poorly designed sidebar or text ad to make just one ad look like too many. A commonly recommended benchmark is a content-to-ad ratio of 4:1 or 5:1 - meaning every ad should be surrounded by at least four to five pieces of quality content. When that ratio tips the other way, users notice, and so does Google.

A TopHatRank study of food blogger domains found that the majority of blogs had over 7 advertisement boxes per single-recipe page, inserted every 2-3 paragraphs. That saturation is a textbook example of what not to do, and it likely explains why so many recipe and lifestyle blogs have struggled with declining organic traffic.

Along Comes Fred - And What Came After

SEO pros named one particular Google update - unnamed by Google themselves - Fred. The Fred update hit early in 2017 and targeted ad density and user experience. Essentially, Google looks at a web page and tries to determine how difficult it is to use organically. How many ads are on the page, and how many of them are obstructing the content the user came to the page to see?

If a user runs a query and lands on a page, they want information. If they’re confronted with multiple ads before they can even see the content, Google will determine that the page has problems. Fred was just the beginning - the Page Speed Algorithm update in 2018 doubled down on this by specifically penalizing pages where excessive ads were contributing to slow load times, opening a second front on which ad-heavy sites could be hurt.

Google weights the value of the content against the number of ads on the page. The more ads on the page, the stronger and more helpful the content needs to be before it can rank without penalty.

On the organic side, your content needs to have as many indicators of value as possible. Having long, focused content without keyword problems, overt fluff, or misinformation is what matters. Including multimedia is great.

Essentially, Google wants you to front-load value as much as possible. They don’t mind if you want to monetize your content. But they don’t want your monetization to get in the way of the value you give to those who show up.

It makes sense. Right? A user wants value from your content when they find you in search. If you make it overly clear that you want money from them more than you want to help them, they’ll be less inclined to trust your site. More importantly, they’ll be less inclined to trust the value of the search results Google provided to them - and that’s why it matters for Google to uphold that trust, so they work to give you the most helpful results.

That’s why so many top-tier sites actually cut back on display ads and focus instead on their own storefronts, affiliate links, or other forms of monetization like consulting or membership programs. If you’re still exploring options, it’s worth reviewing the best ad networks to monetize your blog before committing to a strategy.

• If your content is thin - say, under 300 words - displaying even 5 ads will typically result in a high bounce rate and signal poor quality to Google. Keep it to fewer than 3 ad units, positioned well out of the way of the content. Stick with sidebars and footer banners.
• If your content is mediocre, around 1,000 to 2,000 words with very little in the way of additional multimedia, branding, or support from the rest of your site, you can add a bit more advertising, but you shouldn’t overdo it. Somewhere in the 3-4 ad unit range, maintaining that 4:1 or 5:1 content-to-ad ratio, can be fine. Just don’t build a thin shell site around affiliate links and expect it to rank well if you layer it with additional ads.
• High quality content - over 2,000 words, with multimedia and strong value - can handle more ads. You still shouldn’t let your ad density overwhelm the content, especially if you’re using multiple ad networks, but you can use other forms of marketing as well. This is where an affiliate link and maybe some internal marketing - like for an ebook - can come into play.

Of course, there’s a tier above this; large established publishers can get away with more aggressive monetization basically by virtue of their domain authority and content volume. That said, even big names aren’t entirely immune - algorithm updates have shown that no site is untouchable when it comes to these ad experience signals.

Less is More

The first thing to understand is that fewer ads can be better for your site than more ads. When you have multiple ad units on your site, one of two things happens. Either they display the same content, which makes them redundant and makes your site look bad, or they display different content. When they display different content, they dilute the focus of the ads on your page. Maybe some visitors will want to click on one or another, maybe some will be indecisive enough to not click on either, maybe some will click on one.

The main problem is that the more ads you have, the less focus those ads have relative to your content. If you’re writing about organic produce, you want ads that feature organic produce, so visitors have a genuine interest and are more likely to click. You don’t want five different ads covering produce, supplements, a diet program, unrelated retail, and other tangentially related products.

To an extent, this goes back to the concept of choice paralysis. You give users a choice between two things, most of them will choose one or the other even if neither fits their preferences. You give them ten options, and sure, there could be better choices available. But it’s also quite a bit more work to choose which is best. A lot of users will simply make no choice.

The fact is, one or two very targeted ads are going to perform quite a bit better for your site compared to five or six less targeted ads on a page. When ads align closely with your content, you’ll see more conversions and make more money from them.

Alternative Monetization

There’s a strong case to be made for not running display ads on your site at all. Ads slow down a site’s load time - a factor Google has directly penalized since 2018. They get in the way of content and can hurt SEO in large numbers. And even the best display ads, if you’re at a low to moderate traffic level, are only making you a few dollars a day at best. Meanwhile the ads hurt your search ranking through a number of factors, which could be costing you more than they earn. Other arguments against display ads include:

• A lack of quality control over the ads. Most ad networks give you the basic ability to blacklist specific ads, sites, or keywords, but you still don’t have direct approval and you never know how long something has been running before you catch and deny it.
• A loss of value the user might have contributed. Each click on an ad represents someone making you a few cents, yes, but it also represents someone leaving your site. That person could have brought more value to you if they had stayed.
• An intrusive system. The reason ad blockers are so prevalent is that ads themselves are simply too disruptive. It would be like trying to read a book while someone is constantly interrupting you to pitch a product.
• A potential for trouble. Not only do excessive ads cause a loss of trust, but ads are also one of the most frequent vectors for malicious code distribution online. Using the wrong ad network can expose your users to real security risks.

Generally, it’s just too disruptive and too low value for the possible losses. The main reason so many blogs use ads is basically that it’s easy. All you need to do is place a few ad units in your code and you’re ready to make some money. The barrier to entry is low, even if the profits are too.

Alternative methods for making money are out there. But they tend to need more work. For example, you can run affiliate marketing, or better yet, you can find businesses you like and ask to create a direct affiliate partnership instead of going through a network. These kinds of relationships can generate more revenue than a standard affiliate arrangement, and you have the added benefit of promoting a brand you actively believe in.

The other, more lucrative option, is to build a focused audience and develop a product they would like. News sites do this through membership portals. Educational content sites hide some material behind a paywall or store. Other businesses sell ebooks, courses, or custom software.

Of course, these alternatives are going to need an operating budget and can be expensive and time-consuming. You need to be able to run your site without relying on ad income, and you’ll have to afford development of a product. All the while, you’ll have to be growing your audience in a focused way so they’ll be interested in what you release.

The no-ads path is not for everyone. At very low traffic levels, ads can be a small supplemental income that helps keep a site alive. And at very high traffic levels where visitors don’t stick around long, ads may be the only viable monetization strategy. For others, a more intentional alternative is worth consideration.
