Click-through rate (CTR) is one of the most intensely measured metrics in performance marketing. For many advertisers, this data serves as the first indicator of whether a campaign is connecting with a target audience. Strong CTRs suggest that your advertising is engaging, your targeting is correct, and that your ad placements are positioned where users are most likely to take action.
Optimizing for CTR goes beyond just tweaking a headline or testing a new visual, though: The process of building and optimizing a strong performance marketing campaign is much more nuanced and layered than you might expect. With the help of robust performance marketing platforms, advertisers can navigate this complex environment, taking into account publisher restrictions, compliance nuances, and the underlying relationship between CTR and return on investment (ROI).
Understanding that CTR is part of a multi-dimensional ecosystem is crucial. A high CTR alone doesn’t guarantee conversions, but a consistently optimized CTR will improve algorithmic learning, increase your reach on publisher sites, and ultimately drive more traffic into your sales funnel.
Three Challenges of CTR Optimization
The Mismatch Between CTR and Conversions
It’s tempting to celebrate a high CTR as the ultimate success metric, but clicks are only the beginning of the process. CTR is a top-of-funnel metric, meaning it measures initial user engagement on your ad, not a guaranteed final result. One of the biggest challenges with CTR, then, is viewing this metric within the big-picture context: A high CTR without subsequent conversions can actually be a signal of wasted spend, since this means you’re paying for traffic that’s not generating tangible business outcomes.
This, in turn, highlights a bigger problem, in that performance is going to look different for every business goal. For lead generation, this could mean low-quality form submissions. For app advertisers, it could look like installs without long-term retention. For publishers, engagement may not translate into revenue.
With Realize, the goal is to align click volume with business intent. CTR must always be considered alongside other metrics like conversion rate, number of conversions, cost-per-acquisition (CPA) and return-on-ad-spend (ROAS), rather than in isolation. Without this, you run the risk of optimizing for the wrong outcome that doesn’t align with your overall business goals.
Content Tags
Realize’s automated content tagging system is designed to maintain the integrity of the advertising network by ensuring that ads align with publisher standards. While this protects both users and publishers, it can also create roadblocks for advertisers.
For example, businesses promoting dating apps may be tagged as having “mature themes,” even if the ad itself is compliant with Taboola policies. As the tagging system errs on the side of caution, it can sometimes mean that ads suitable for general audiences are prevented from running on premium publishers.
This can be a significant challenge, as premium publishers typically deliver the highest CTRs and strongest engagement rates; ads flagged with these content tags are missing out on access to a portion of these networks’ highest-quality traffic. This directly impacts a campaign’s potential performance and ability to achieve a higher CTR.
With proactive management, content tags can be worked around in order to enhance your CTR performance. Regularly reviewing your campaign dashboards for any creative flagged with tags should become a routine part of your workflow.
Realize account managers see whether any creative tagged with this label is justified. If the creative is determined to be compliant with our core policies, they can help you submit a remediation request with their policy team to have the tag removed.

Campaign Approval and Formatting Issues
Small but significant details can make or break your performance marketing campaign. Something as simple as an incorrect capitalization, DKI keyword, or incorrectly cropped image file can cause an ad to be rejected.
For instance, languages like German have capitalization rules where nouns are always capitalized. An ad that ignores this rule could be automatically rejected, even if everything else about the ad is correct. Or, consider a creative that includes punctuation at the end of a headline. Ultimately, what may seem like a stylistic choice could violate formatting standards that result in rejection, and what may seem like minor inaccuracy can have a disproportionate impact on your overall campaign performance.
Rejected ads can also eat up valuable time for the advertiser: With a time-sensitive launch like seasonal sales, rejected ads mean that you might miss critical sales windows. This highlights the core challenge of optimizing creatives — that success often depends on operational precision as much as on creativity.
Actionable Recommendations to Optimize CTR Using Realize
Creative A/B Testing
Creative tests are a foundational element of CTR optimization. Without it, advertisers run the risk of stagnation as audiences grow tired of seeing the same ads, otherwise known as ad fatigue. This can result in performance decline as conversion rate and CTR go down, even if all the targeting remains the same.
With Realize, advertisers can continuously test headlines, images, and video thumbnails to find better variations. Running short-term tests, around 48-72 hours, can help you see if new creative outperforms previous ads in terms of both impressions and CTR. Applying frameworks like PANDA (Pre-test, Analyze, Narrow, Deploy, Assess) can also be beneficial, so you can strategically validate which creatives have the strongest CTR lift.
The key to success with A/B testing is to test systematically, rather than sporadically. That means always having a consistent pipeline of creative assets to run, then making decisions based on the data from the results of these experiments. By testing in a continuous loop, you’re better able to optimize CTR over time.
Strategic Targeting with Publisher Data
One of the most underused tools in CTR optimization is publisher-level data. Many advertisers assume that they need to build rigid whitelists to secure top placements, but this isn’t always the case. With a strong CTR performance and sufficient budget, Realize’s algorithm naturally favors high-performing publishers. In addition, working directly with your account manager to get access to premium publishers can be a significant competitive advantage.
The value of this approach is that it keeps your efforts data-driven, rather than assumption-driven. For example, if a campaign has a strong CTR but isn’t winning impressions on a premium publisher site, the issue could be budget constraint or a creative misalignment. However, if the campaign is already appearing on top-tier publisher sites, a whitelist might not be needed.
By grounding your decisions in publisher data, you’re better able to refine your CTR optimization strategies without over-restricting your campaign scalability.
What the Advertiser Can Expect
Increased Impressions and Reach
By resolving content tag and formatting issues, along with continually refreshing creative, you’ll see a significant boost in campaign reach. This doesn’t only mean an increase in overall impressions, but more impressions on high-quality publisher sites where CTR potential is the highest.
This lift can be significant. Studies have found that ad placements in premium environments can deliver up to 36% higher engagement compared to non-premium placements. With Realize, unlocking this level of premium inventory can be a campaign-changing strategy.
Improved Overall ROI
While CTR is important, it’s not the ultimate goal — that would be better return on ad spend and increased ROI. Better CTR often leads to lower cost-per-click (CPC), which makes your spending more efficient while generating higher volumes of qualified traffic. Overall, you can expect to see higher conversion volume at the same spend level, lower customer acquisition costs, and higher ROAS as every dollar works harder throughout the sales funnel.
Advertisers who choose to invest in creative testing and compliance management can see significant increases in ROI, and Realize can boost that further thanks to algorithmic reinforcement, making CTR optimization one of the most impactful avenues for profitability.

Frequently Asked Questions (FAQs)
What are some practical ways to maintain a consistent pipeline of fresh creative assets for ongoing testing?
“The most practical way is by utilizing AI tools, which can really help to create a lot of assets and make them variable,” says Kamilla Tursunova, media account manager, growth, at Taboola. “We recommend using Realize Generative AI — ad creators know they need to produce fresh, high-quality content on a continuous basis to stay ahead of the competition and drive sustainable results.”
If you have a high CTR but low conversion rate, what would be your first steps to diagnose the problem?
The first step is to evaluate the post-click experience. Does the landing page match the content that the ad has promised? Check factors like page load speed, mobile usability, form length, and the clarity of calls-to-action (CTAs).
With Realize, you can connect CTR data with conversion tracking to identify where in the funnel a breakdown may be occurring. If the ad attracts clicks but the landing page fails to convert, the issue is likely there, rather than creative-driven.
What are specific, actionable tactics you would use to improve CTR for a search campaign?
Improving CTR search campaigns requires both relevance and strong presentation. Align ad copy directly with user intent by matching headline phrasing to top-performing search queries. Use specific CTAs that promise clear value, such as “schedule a demo,” instead of a more generic “learn more.” You can also use ad extensions like siteclicks or callouts to provide more clickable entry points from your ad.
When used with Realize’s creative testing framework, these tactics allow your search campaigns to continually evolve to capture user attention at scale.
How can advertisers balance using publisher data for optimization without unintentionally limiting campaign reach or scalability?
“According to our best practices, we recommend making all optimizations based on the data that you can find on your Realize dashboard,” says Tursunova. “First of all, don’t rush to pause sites: We encourage you to start optimizing only when the campaign’s learning phase is over, which is usually two to three days after the campaign is launched. In addition to that, the minimum requirement is to have at least 100 clicks on each publisher and spend that equals 2-3x the expected CPA goal. This threshold provides enough data to assess performance accurately, while preventing unnecessary overspend.”
How can you use data and analytics to inform your CTR strategy?
Data is the foundation of an effective CTR optimization strategy. By reviewing and analyzing performance across creatives, audiences, devices, and publishers, you can discover which factors are consistently driving better performance.
With Realize, you’ll gain access to granular reporting that provides publisher and ad level CTR performance data. By comparing campaign data against competitive benchmarks, you can identify gaps in your current strategy and invest more in high-performing creatives and publishers.
