SEO Tests

Run controlled before/after experiments on your website using real Google Search Console data. Capture a baseline, make your changes, then check back to see if they worked.

What it does

SEO Tests lets you measure the real impact of on-page changes by comparing GSC snapshots taken before and after you apply them. Instead of guessing whether a title tag rewrite or content update helped, you get hard numbers: clicks, impressions, CTR, and average position deltas.

Find it at Dashboard → SEO Tests.

Use cases

  • Title tag experiments — rewrite title tags on low-CTR pages and measure the CTR lift after 2-4 weeks.
  • Content updates — expand thin pages with richer content and track whether impressions and clicks increase.
  • Internal link campaigns — add internal links to a set of pages and see if average position improves.
  • Schema / structured data — add FAQ or HowTo schema and measure CTR changes from rich snippets.
  • URL restructuring — move pages to a new path structure and verify traffic is maintained or improved.
  • pSEO enrichment — enrich programmatic pages and measure the before/after impact on the entire subfolder.

How it works

Every test goes through three stages:

1. Baseline

When you create a test, Massblogger captures a snapshot of the last 28 days of GSC performance data for the pages and queries matching your filters. This is your “before” state.

2. Running

After you make your changes (title rewrites, content updates, etc.), click Start test and describe what you changed. The test enters the running state. A countdown shows when enough time has passed to check results — typically 14 days, but configurable up to 90.

3. Completed

Click Check results to capture a new GSC snapshot. Massblogger computes the percentage change for clicks, impressions, CTR, and average position. You can re-check any time to get updated numbers.

Filters

When creating a test, you can narrow the scope with two optional filters:

  • Page contains — only include pages whose URL contains this string. For example, /blog/ to test only blog posts.
  • Query contains — only include rows where the search query contains this string. Useful for tracking a specific keyword cluster.

Understanding results

Once a test is completed, you see four metric cards comparing baseline vs. result:

  • Clicks — total clicks in the snapshot period. Green arrow up = more clicks.
  • Impressions — total impressions. An increase means your pages are appearing in more searches.
  • CTR — click-through rate. Higher CTR usually means better titles and meta descriptions.
  • Avg. Position — weighted average ranking position. Lower is better, so a decrease is shown in green.

Below the summary, a table shows the top 10 individual pages or queries with per-row deltas so you can see which specific pages improved or declined.

Tips

  • Wait at least 14 days before checking results. GSC data has a 2-3 day lag, and Google needs time to re-crawl and re-rank pages.
  • Use specific filters to isolate the pages you changed. Testing your entire site makes it harder to attribute changes.
  • Keep a clear hypothesis. Writing down what you expect to happen helps you evaluate whether the result is meaningful or noise.
  • Re-check after 30 and 60 days. SEO changes can take weeks to fully materialize, so early results may understate the impact.

Requirements

SEO Tests requires a connected Google Search Console property. Make sure your website is verified in GSC and that you have granted Massblogger access during onboarding. The website must have enough data in GSC for the snapshots to be meaningful.
