Pain points

Every SEO's Monday morning.

These are not edge cases. These are the job.

The 5-Tool Shuffle01

Your client asks for a report. You open Screaming Frog, Semrush, PageSpeed, GTmetrix, and Google Slides. Three hours later, you have a report.

One Chrome and Firefox side panel. Everything Screaming Frog, PageSpeed, and Semrush cover in one click.

Saves 3+ hrs
The 3-Hour Report02

You spent the time. You did the analysis. Now you spend another 90 minutes turning it into slides that may or may not get read.

Branded PDF in 10 seconds. Three templates. Your logo. Done. Your clients will think you spent hours.

Saves 1.5 hrs
The Jargon Wall03

"What does LCP mean?" Your client forwards your report to their boss. The boss replies asking the same question.

Plain English Mode translates every technical finding into language any client understands.

Zero questions
The Proof Problem04

You fixed the issues. The score went from 61 to 84. But you didn't screenshot the before state.

Before/After Snapshots. Timestamped proof of every issue resolved. The most compelling thing you can show in a monthly review.
