Every year, advertisers lose thousands to low-quality ad sites. Advertisers expect their display ads to appear on reputable sites, but without controls, this rarely happens.
Programmatic ad networks can force ads to millions of placements, and none of them are the same. Some are loaded with spam traffic, deceptive content, or even malware.
This article explains how to spot, block, and prevent low-quality ad sites from draining your campaign budget, with automation tools like ClickPatrol doing the heavy lifting.
What are low-quality ad sites?
Low-quality ad sites don’t provide real value to users and exist primarily to generate ad revenue.
Low-quality ad sites often contain thin or scraped content, intrusive pop-ups, excessive ad placements, or simulated traffic designed to inflate ad impressions and clicks. Some characteristics of low-quality ad sites include:
- Clickbait or misleading headlines for the purpose of driving views only.
- Bot-generated or non-human traffic, exaggerating impressions and clicks.
- Content farms that repost low-effort, copied content.
- Made-for-advertising (MFA) sites are heavily loaded with ads and offer little to no genuine content.
- Deceptive or off-topic content, including adult, political, or extremist content.
- Fake news or disinformation can harm a brand’s reputation.
While these sites might seem like insignificant annoyances, their total effect on a brand’s performance and reputation can be overwhelming.
How to identify low-quality ad sites in your campaigns
You should be able to identify low-quality placements before you can block them. The following is how you can locate possible problem areas in your campaign data:
Analyze placement reports
Check the areas or web addresses on which your advertisements are running. Look for patterns like:
- Strange domain names containing numbers, hyphens, and random strings.
- Web pages that get many impressions but few clicks or conversions.
- A location that has no relevance to your target audience or industry.
Check engagement metrics
Poor-quality sites typically exhibit high bounce rates or short session times, or zero conversions. These are warning signs that the traffic can be non-human or irrelevant.
Audit site content
Visit the suspicious placements manually.
- Is the site legitimate?
- Is it original, useful, and relevant content? Otherwise, it is likely a low-quality advertisement site.
Use verification tools
Brand safety and verification tools can scan placements for fraud, malware, or inappropriate content.
However, while helpful, these tools can be complex to manage manually, and that is where ClickPatrol simplifies the process.
Step-by-step: How to block low-quality ad sites
In case you are running display campaigns on such platforms as Google Ads or programmatic networks, there are a few things that you can do to prevent exposure to poor placements:
Use placement exclusions
Excluding specific sites or areas from your campaign is possible. Check your placement report regularly and block suspicious or irrelevant sites.
Add negative keywords
Negative keywords ensure that you do not advertise on such material as gambling, politics, or adult content.
Adjust targeting settings
Target users more effectively and exclude irrelevant topics to minimize random placements. Pay attention to sites within your niche or target market.
Opt for managed placements
Rather than using automatic placements, select a list of sites where you would prefer your ads to be placed. Although this method is more time-consuming, it gives you control over ad quality.
Regularly audit campaigns
Establish a schedule (once a week or once a fortnight) to go through placement reports. Even the best campaigns can end up appearing on low-quality sites over time if left unchecked.
These measures are necessary but can be tedious, especially when advertisers manage multiple campaigns. That is why automation is key.
