How to Boost Your Ad Revenue Beyond Fill Rate Optimization

As publishers, you know how important it is to have a steady income stream to keep your content flowing. Ad revenue plays a crucial role, and maximizing every impression is critical. That's where ad fill rates come in.

Simply put, a higher ad fill rate means more ads displayed, leading to more ad revenue. But is it that simple? Imagine your website as a powerful engine capable of generating significant returns. If it operates only at half capacity, you are losing potential income. This scenario reflects the impact of low ad-fill rates. 

While ad fill rates might seem technical, navigating this metric requires understanding its intricacies for fruitfully optimizing revenue. However, fill rates are just one part of the ad revenue equation, and making money needs more than fill rate optimization. 

This guide will:

• Explain what ad fill rates are and how they are calculated.
• Highlight real-world scenarios & your financial well-being.
• Provide practical strategies for optimizing your fill rate.

And help you know that it's not just about achieving a 100% fill rate but about securing the best price for each impression.

Ad Fill Rates

An ad fill rate measures the percentage of ad requests successfully delivered on your website. It reflects how effectively you utilize your ad inventory to generate ad revenue.

Think of your website as a digital billboard with spaces available for advertisements. Each space represents an opportunity to earn money by displaying an ad. The ad fill rate tells you what percentage of those available spaces are currently filled with an ad that visitors can see. So, a higher fill rate means a higher portion of your ad spaces are working for you, bringing in potential revenue.

Is a higher fill rate always better?

Not necessarily. A higher fill rate indicates strong ad inventory utilization. But it also possibly means that you are prioritizing quantity over quality. With irrelevant and intrusive ads, you can harm the user experience, which will ultimately hurt your ad revenue.

So, what's a "good" fill rate? 

Sadly, there's no one-size-fits-all answer to this question. It depends on factors such as the type of ad formats, the platform, and results might also differ conditional to each ad network. 

Ad fill rate is just one part of the puzzle and considering another metric called eCPM (effective cost per thousand impressions) is a must. 

eCPM calculates the actual revenue generated per ad, providing a more balanced approach and a holistic view of your overall ad performance.

A lower fill rate paired with higher eCPM might actually turn out to be more profitable!

Let’s Talk Money: From Fill Rates to eCPM & Overall Ad Revenue 

The ANA report on media quality and revenue disconnect:

The Association of National Advertisers (ANA) report highlights a notable gap between media quality and revenue for web publishers.

Despite delivering high-quality impressions, there is a disconnect as these premium offerings don't necessarily translate into higher earnings for publishers.

Which means although you have an increased fill rate and ads are being viewed - yet it isn't offering you substantial ad revenue.

Around 64 cents of every ad dollar vanishes before it reaches you:

A report says only 36 cents is left for you from every dollar advertisers spend on your content. That's the harsh reality, with nearly two-thirds (64%) disappearing due to:

• Ad-tech fees: 29 cents are siphoned off by exchanges, platforms, and intermediaries. That's money that could have gone directly to filling your ad slots.
• Wasted spending: Another 35 cents vanish on "low-quality media" like fake traffic and unseen ads. 

This leaves a much smaller budget for advertisers to bid on your valuable ad space. With less money chasing the same inventory, two things happen:

1. Bidding wars: Competition gets fierce, potentially pushing up prices beyond some advertisers' reach, leaving your ad slots unfilled.
2. Fewer bidders: With a smaller budget, some advertisers drop out, shrinking the pool of potential buyers for your ad space.

All of this leads to lower fill rates and less ad revenue for you.

So, why are campaign inefficiencies hurting your fill rate?

While campaigns aim for diversity, the reality is stark - 63% of ad requests land on just the top 500 sites, leaving crumbs for the rest. This leaves us facing two major roadblocks to achieving decent fill rates:

1. The "Hunger Games" of ad requests: Think of a battle royale where only 37 ad requests are dropped across 44,000 publishers. The odds of grabbing one aren't exactly in your favor. This limited pool, coupled with potential targeting issues and technical hurdles, makes filling your ad slots even harder.
2. The"Exclusive Club" problem: Advertisers often cozy up to the big guys, missing out on your unique audience and diverse inventory. This means they miss valuable connections, and you miss out on high-quality ad revenue, further impacting your fill rate.

Real-World Scenarios: You Need More Than Fill Rate Optimization 

Let’s look at some real-world scenarios, from fluctuating market trends to evolving tech challenges. These scenarios shed light on the multifaceted challenges publishers have to face and prove that you need to go beyond fill rate optimization.

Why are fill rates often stuck at a stingy 1%?

Ever feel like you need to get more ad requests? You are not alone. Fill rates are often stuck at a stingy 1%, and that's a bummer. 

The culprit? 

• Complex partnerships: Publishers juggle multiple SSPs and exchanges, each connected to numerous DSPs. This multiplies a pool of 10 potential bidders into a chaotic crowd of 100+.
• Duplicate requests: DSPs receive the same impression repeatedly, creating inefficiency and missed opportunities for unique bids.
• Header bidding woes: While offering control, header bidding can exacerbate duplication if not managed effectively.

A recent article on ADWEEK highlighted this issue, stating, 'The standard fill rate is just 1%, meaning that only 1% of ad requests receive a response from advertisers or buy-side tech partners.  This low fill rate is attributed to duplication and inefficiency in the programmatic supply chain, worsened by the spread of supply paths, especially with the introduction of header bidding.

So, for you as a publisher, it's evident that the challenge lies in taming this complexity, limiting duplication, and streamlining supply paths. 

By doing so, you can boost your fill rates and ensure that more ad requests find their mark, avoiding the black hole effect that currently plagues the efforts.

Fill rate optimization in the cookieless world:

Here's what’s happening:

1. Cookie crumbling means targeting troubles: Cookies were used to provide valuable insights into audience behavior, enabling precise targeting. Without them, reaching the right users with relevant ads becomes a challenge, potentially impacting both fill rates and ad revenue.
2. Blind spots mean missed revenue: Without deep audience understanding, you are essentially guessing what ads will resonate, leading to suboptimal CPMs and potentially leaving high-value advertisers on the table.
3. The competition is heating up: As everyone scrambles for first-party data, publishers who haven't invested in this area risk being left behind in the fight for ad dollars.

To optimize fill rate, try building your audience map - first-party data is the new goldmine. By collecting data directly from your users through authentication methods like games, newsletters, and chatbots, you can understand your readers' interests, preferences, and demographics, enabling laser-focused targeting that attracts more relevant advertisers.

By demonstrating deep audience understanding, you become a more desirable partner for advertisers, potentially negotiating higher CPMs and boosting overall revenue. You must foster closer connections with your audience, creating a loyal community that's more receptive to advertising, improving both fill rates and engagement.

Here’s the proof - Unwind Media, a gaming publisher. By implementing first-party data solutions, they saw a 51% increase in CPM and an 11% rise in fill rates, demonstrating the tangible benefits of this approach.

Other challenges in the quest for high fill rates

Maintaining a stellar fill rate is not easy, and having ad slots filled at all times can be restricted by several challenges, such as:

• Ad latency
• Higher floor price
• Potential ad fraud
• Geo locations
• The omnipresent ad blockers
• Website's user experience
• Ad quality or ad relevance
• Bad network or technical issues
• Ever-changing ad technologies

While achieving a high fill rate is a desirable goal, it alone is not sufficient for maximizing ad revenue. Here's the real deal:

1. Setting low floor prices might guarantee filled slots but hamper your brand quality. It can also scare away potential bidders, leaving you with lower-paying ads instead of maximizing competition and driving up CPMs.
2. Show bad ads, users get annoyed, click less, and your earnings drop.
3. Website or network issues? Ad delivery suffers, and money gets left on the table.
4. Annoying ads lead to blockers and eventually less ad revenue for you.

Remember, a high fill rate is just the beginning. Focus on quality, user experience, and smart strategies to truly boost your ad revenue!

So, What Do You Do as a Web Publisher?

As a web publisher, these insights underscore the need for strategic adjustments. You need to explore the true potential of your ad inventory and ensure that every impression contributes meaningfully towards the revenue stream and not just the fill rate.

So, forget the fill-rate obsession! Here's your action plan for maximizing ad revenue that matters:

1. Quality takes center stage

Ditch low-quality ads and opt for relevant, engaging experiences that drive clicks and revenue. When navigating the dynamic scape of CPM vs. fill rate, prioritize optimal floor prices using real-time data tools like Mile's AI powered flooring. This ensures the highest CPM without compromising the fill rate.

2. Price like a pro: 

Forget static pricing. Tools like Mile’s Dynamic Flooring use machine learning to analyze real-time data and set optimal floor prices, ensuring you get the highest CPM without sacrificing fill rate..

3. Know your audience: 

Build first-party data through games, newsletters, etc. Unlock laser-targeted ads that attract premium advertisers willing to pay more.

4. User experience (UX) matters

It is never UX vs. fill rate, you have to prioritize user experience (UX) by creating a website that users love – intuitive navigation and respectful ad placements will boost fill rate and get you more ad revenue.

5. Experiment & optimize

Continuously A/B test different ad formats, placements, and pricing. Experimenting with different strategies allows you to make data-driven decisions and optimize your approach for maximum impact on both UX and ad revenue.

Remember: It's not about filling slots, it's about building valuable connections with your audience and delivering genuine value to everyone. Implement these strategies to unlock sustainable ad revenue in the ever-changing digital landscape.
