How to Use Scan Comparisons to Track Your Site's Improvement

Stop Guessing Whether Your Changes Made a Difference

You spent last weekend optimizing your images, adding author bios, and fixing broken links. Your AdGateScore went from 72 to... you don't know, because you didn't save the old scan. So you run a new scan, see 78, and think "that seems higher?" But you're not sure what caused the improvement or whether some things actually got worse while others got better.

This is exactly why we built Scan Comparisons. Pick any two scans of the same site and see them side by side — every module score, every check, every metric — with clear green/red indicators showing what improved and what regressed. No guessing, no fuzzy memory, just data.

Why Single Scans Aren't Enough

A single scan tells you where you stand right now. That's useful, but it doesn't answer the question that actually matters: "is what I'm doing working?" Without a comparison point, you can't attribute improvements to specific actions, you can't detect regressions from site changes, and you can't measure ROI on optimization work.

Think of it like stepping on a scale. Knowing you weigh 175 pounds is information. Knowing you weighed 185 pounds last month is insight. The comparison creates the narrative that drives better decisions.

How to Use Comparisons Effectively

Before/After Optimization: The most common use case. Run a scan before starting any optimization work. Save or bookmark that scan URL. Do your fixes. Run a new scan. Compare the two. You'll see exactly which checks went from fail to pass, which module scores improved, and — critically — whether any checks regressed (it happens more than you'd think, especially when site changes have unintended side effects).

Pre/Post Redesign: As covered in our redesign guide, documenting your baseline before a redesign is essential. The comparison view makes it dead simple to verify that your redesign didn't break things — structured data still present, meta descriptions still populated, page speed still acceptable.

Monthly Health Checks: Run a scan monthly and compare against the previous month. Over time, this creates a trail of improvement (or regression) that keeps you accountable. Sites that scan monthly and act on the results consistently outperform sites that scan once and forget about it.

Reading the Comparison View

The comparison shows modules side by side with percentage change indicators. A green +5 next to Performance means that module improved by 5 points. A red -3 next to Architecture means something regressed. At the check level, you'll see individual items that flipped from fail to pass (wins) or pass to fail (problems).

Focus on the regressions first. Improvements are great, but regressions are urgent — they mean something broke or degraded since your last scan. A new broken link, a missing meta description on a recently published page, or a speed regression from a new plugin should be addressed immediately before they accumulate.

Using Comparisons for Network Applications

If you're preparing for a premium network application, the comparison view is your progress tracker. Run a scan today, note your readiness percentage for your target network, work on fixes for 2-4 weeks, then scan again and compare. When your readiness percentage is consistently above 90% across multiple scans (not just one lucky scan), you're ready to apply with confidence.

Some publishers include comparison screenshots in their network applications as evidence of active site improvement. It shows the reviewer that you're not just meeting the bar — you're actively raising it.

The Compound Effect of Regular Comparisons

Publishers who compare scans monthly improve their scores 3x faster than those who scan sporadically. The reason is simple: regular comparison creates accountability. When you can see that last month's score was 76 and this month's is 74, you're motivated to investigate and fix what changed. Without the comparison, that 2-point regression goes unnoticed until it compounds into a 10-point drop over six months.

Start your comparison baseline today. Run a scan, bookmark the result, and set a calendar reminder to scan again in 30 days. That first comparison will be the most revealing one — you'll see exactly where your site stands and where the biggest opportunities are.
