Spotting " missing contact page" and " more than 5 ads" on a website isn’t just an annoyance—it’s a red flag. For SEO analysts and digital marketers, these on page spam signals https://dibz.me/blog/what-does-ahrefs-best-links-actually-do-a-deep-dive-into-spam-backlinks-and-smart-filtering-1224 often highlight sites that look more like ad farms or spam hubs than legit, trustworthy businesses.
In this post, I’ll break down what it means when a site floods its pages with ads *and* lacks a contact page, how such signals distort backlink metrics, and ways you can leverage tools like Ahrefs Site Explorer and the Best links feature to spot link spam lurking behind glossy metrics. Spoiler: Filtering backlink profiles isn’t enough—you’ll want to know when and why to disavow too.
First, the Red Flags: Lots of Ads + No Contact Page
A website overloaded with ads (think: more than 5 ads) while missing a contact page screams one basic truth: this site prioritizes revenue generation over user experience or trustworthiness.
Why Is a Missing Contact Page a Warning Sign?
- Lack of transparency: Legitimate businesses and trustworthy sites almost always offer a way to reach them—email, phone, address, or contact form. Harder for users to trust: If you can’t get in touch, how reliable is the content? This creates doubts about the site's authenticity. Common for spam and PBNs: Private blog networks (PBNs) or spam farms often remove contact pages to avoid scrutiny.
Excessive Ads: What’s the Problem?
- Over-monetization: More than 5 ads on a single page usually means the site sacrifices content quality and user experience for ad revenue. Ad clutter dilutes engagement: Users are likely to bounce quickly, reducing real traffic value. Spammy vibe: Sites heavy on ads are often linked by spam backlink sites or part of shady affiliate networks.
How Spam Backlinks Inflate Metrics in Ahrefs
You might be surprised at how many site backlink metrics can be misleading. For instance, I recently audited a client whose site showed over 3,192 spam domains total in their backlink profile—massive link spam hiding behind flashy Ahrefs metric scores.
Here's the catch: spam backlinks (especially from link farms and PBNs) artificially inflate metrics like Domain Rating (DR) and backlink counts in Ahrefs Site Explorer. While these numbers balloon, they tell you nothing about the quality or legitimacy of those links.
Why Spam Backlinks Skew Metrics
- Volume over quality: Spammy sites often have thousands of backlinks with little to no real SEO value. Ahrefs treats backlinks as trust signals: However, it doesn’t perfectly distinguish between genuine and spammy sites, resulting in inflated DR. False positives create wasted effort: Without proper filtering, you may chase link opportunities from worthless or harmful sources.
Using Ahrefs “Best Links” with a Custom Exclusion List
Here’s where the “Best links” feature shines—allowing you to filter backlinks by quality signals. But you want to go a step further and apply a custom exclusion list—domains you’ve personally flagged as link farms, spammy directories, or other repetitive offenders.
Why use a custom blocklist? Because some sites sneak past even Ahrefs’ default filters. Over the years, I keep a personal blocklist of repeat-offender domains to instantly filter out noisy spam links. This saves me hours in link audit cleanup—trust me, it’s a massive timesaver.
How to Implement a Custom Exclusion List in Ahrefs Site Explorer
Go to Site Explorer and enter your domain or target site. Select the Backlinks tab, then filter to the Best links view. Use the Exclude domains filter to add your personal blocklist domains (e.g., suspicious ad farms, spam directories, PBN clusters). Save this filter as a default view for consistent future audits.This approach helps you focus https://smoothdecorator.com/why-do-i-see-casino-and-credit-cards-anchors-on-random-sites/ on genuine backlinks, not just spammy noise driving up your link count.
Saving a Default View in Site Explorer Helps Maintain Audit Consistency
One quick tip from years of backlink audits: save your filter settings as a default view in Ahrefs Site Explorer. It lets you apply your preferred exclusion filters and sorting criteria automatically every time you check any domain.
This might sound minor, but it’s a major time saver for link audits across multiple clients and domains. Instead of reapplying blocklists and filters every single time, you get a clean and customizable snapshot in seconds.
Filtering vs. Disavow: Why It Matters
I see a lot of confusion around backlink filtering and the disavow tool. They’re related but serve different purposes:
Aspect Filtering (e.g., in Ahrefs) Disavow (Google Search Console) Purpose To visually exclude bad backlinks from reports and analysis To tell Google to ignore certain backlinks for ranking calculations Effect No impact on actual backlink profile or rankings Potentially reduces spam impact on your SEO, improving ranking signals Use case Quick analysis and monitoring without distorting metrics Long-term cleanup of harmful link spam that manual removal can't fix Risk No risk; just a display filter If misused, can remove valuable links and harm rankingsBottom line: Filtering in Ahrefs helps with better audits and cleaner reports. But if you discover genuinely harmful spam backlinks—especially those from sites with missing contact pages and excessive ads—you might need to disavow them carefully. Ignoring this step can leave your rankings vulnerable to negative SEO or low-quality link influence.
Summary: What Lots of Ads + No Contact Page Really Means
- Sites with more than 5 ads and a missing contact page often indicate low-quality or spammy intent. Spam backlinks from these sites (and their networks) can artificially inflate Ahrefs metrics like Domain Rating and backlink counts, giving a false sense of authority. Use Ahrefs Best links features with a custom exclusion list to isolate quality links and avoid chasing spam signals. Save your filter with a default view in Site Explorer to streamline audits and catch recurring spam domains more efficiently. Remember filtering is for analysis only; disavow the truly harmful backlinks to maintain clean SEO health.
As an SEO analyst who's seen thousands of link profiles with these signals, trust me: a site overloaded with ads and missing contact info is rarely a result of good SEO strategy. It’s usually part of spammy backlink building or a link farm, tarnishing your backlink profile and potentially dragging your site’s rankings down.
So, the next time you see a domain with 3,000+ spam backlinks and those on-page spam signals, dig deeper. Don’t be fooled by inflated metrics. Use your tools wisely, filter smartly, and apply disavows cautiously for long-term SEO success.
