How Do I Check Indexation Issues as Part of Spam Scoring?

If you’re managing SEO for a website, especially one with a complex backlink profile, you’ve probably seen misleading metrics from tools like Ahrefs that don’t tell the full story. One common issue is fourdots.com how spam backlinks inflate Ahrefs metrics, skewing your perception of a site's health and authority. This is where understanding Google indexation and indexation status of your backlinks comes into play as a crucial spam signal.

In this guide, I’ll walk you through practical steps to check indexation issues as part of your spam scoring methodology, leveraging Ahrefs Site Explorer's powerful features, including the often-underused “Best links” view combined with a custom exclusion list. Along the way, we'll uncover why filtering backlinks in your SEO tool is not the same as disavowing, and why knowing the difference actually matters.

Why Spam Backlinks Inflate Ahrefs Metrics

Before diving into the mechanics, let’s clarify a common misconception: many SEO folks mistake filtered backlinks for true spam signals, or worse, confuse filtering with Google's perception of your backlink profile. Here’s the deal — not all backlinks shown in tools like Ahrefs are equal.

Spam domains often inflate metrics such as Domain Rating (DR), backlinks count, and referring domains number. For example, one profile I recently audited showed nearly 3,192 spam domains total, many of which are low-quality link farms or private blog network (PBN) leftovers. These artificially boost Ahrefs metrics even though Google typically ignores or penalizes sites for these.

Spam backlinks may be indexed or de-indexed by Google. Unindexed spam links do not pass any real SEO value. Ahrefs reports them as backlinks regardless, inflating domain metrics.

This is why just looking at raw backlink counts or even Ahrefs's spam score (not to be confused with their filter options!) is insufficient. You need to verify if such backlinks are actually indexed — a true spam signal — before deciding your next move.

Step 1: Using Ahrefs Site Explorer to Check Backlinks

You’re probably familiar with plugging your domain into Ahrefs Site Explorer, but here’s a quick framework tailored for indexation issues:

Open Ahrefs Site Explorer and enter your target domain or URL. Go to the Backlinks report to view all known backlinks. Switch to the Best links tab — this filters to the highest quality links Ahrefs identifies.

But why the “Best links” tab? Because it automatically filters out many low-value or spammy links, giving you a cleaner dataset to start with. However, the default “Best links” filter can still be improved by applying a custom exclusion list.

Creating a Custom Exclusion List

Here’s where the seasoned pros separate themselves from the amateurs. I always maintain a personal blocklist of repeat-offender domains — known link farms, PBNs, and suspicious networks that routinely appear as spam but sneak past default filters.

To implement this:

Export your backlinks from the “Best links” view. Identify known spammy domains from your blocklist or by manual review (checking domain authority, traffic, or tool signals). Use Ahrefs's filtering options to exclude these domains from your backlink report. Save this filtered view as a default view in Site Explorer for quick future access.

By doing this, you effectively reduce noise, so your spam scare cloud clears, and you see only relevant links that truly matter.

Step 2: Verifying Google Indexation of Backlinks

Why is indexation status crucial? Because if spammy backlinks are not indexed by Google, then they hardly pose a direct risk. On the other hand, if low-quality backlinks are indexed, they present a genuine spam signal that could hurt your rankings.

Practical ways to check indexation status of backlinks include:

Google Search Operators: Use site:domain.com/linked-page or direct URL searches to see if backlinks pages are indexed. Third-Party Index Checker Tools: Bulk index checkers provide insight into which URLs are live in Google. Cross-reference with Ahrefs link data: Filter backlinks in Site Explorer that exist on indexed URLs.

This process sounds tedious but can be streamlined by matching backlink URLs against your own indexation checks and applying those findings as further custom exclusions.

Step 3: Filtering vs Disavow — Why It Matters

Many SEO practitioners confuse filtering in Ahrefs or other tools for the same thing as disavowing links via Google Search Console. These are not the same, and that misunderstanding can create costly mistakes.

Filtering (in SEO tools) Disavow (Google Search Console) Temporary way to hide or exclude spammy links in your reports Official Google method to tell Google to ignore certain backlinks when evaluating your site Does not affect your website’s real backlink profile or search rankings Changes how Google interprets your backlink profile; can prevent penalties Useful for analysis and prioritizing link cleanup Used when spam links pose risk or when link removal is impossible

So, while filtering links in Ahrefs lets you understand what’s junk vs clean, disavowing is the actual cleanup tool. It’s critical to base your disavow decisions on backlinks that are not only spam but also indexed by Google — hence the importance of analyzing indexation status as part of your spam scoring.

Putting It All Together: A Real-World Example

Imagine a backlink profile with 3,192 spam domains total. If you blindly trust Ahrefs metrics without checking indexation, you might panic.

Here’s how you’d approach it properly:

Start by loading your domain into Ahrefs Site Explorer. Go to the Best links view to minimize noise. Apply your custom exclusion filter removing your blocklisted spammy domains. Save this solid view as your default to track over time. Export backlinks from this refined list and check indexation status via Google or other tools. Identify which spam backlinks are actually indexed — those are your priority candidates for disavow. Submit a disavow file (if necessary) to Google Search Console targeting only indexed spam links.

This method avoids over-filtering that hides potentially valuable backlinks and prevents wasting time on dead, unindexed spam.

Final Thoughts

Don’t fall for simplistic spam scoring methods that rely purely on backlink volume or generic “spam scores” from SEO tools. Instead, invest a few minutes daily cleaning up profiles in Ahrefs Site Explorer, leveraging the Best links feature with a smart exclusion list, and validating actual Google indexation status.

Remember:

Spam backlinks artificially inflate Ahrefs metrics. Indexation status of backlinks is a critical spam signal. Filtering in tools is not the same as Google disavow. Saving custom views in Ahrefs speeds up repeated audits.

By mastering these steps, you’ll save hours on toxic backlink cleanups, make confident disavow decisions, and keep your site’s SEO standing strong without misleading data.

Now, go open Ahrefs Site Explorer and start refining your spam scoring based on real, actionable indexation insights!
