About
Flatline SEO started as an internal tool. We needed a faster way to know where a website stood online, and we needed it in language a normal person could understand.

Our origin
We started by auditing local businesses on our own doorstep in Belfast. That hands-on experience shaped every feature. Now businesses in 40+ countries use the same tool. Those roots keep us grounded. The product keeps growing.
Creative Crew Studio needed a way to pre-vet prospects before door-knocking. We built a scrappy auditor that scored websites on a 0 to 10 scale.
WooRank, SEOptimer, BrightLocal. We tried them all. Too expensive, too bloated, or too confusing for the businesses we were trying to help.
One score (0 to 100), plain-English findings, a fix priority list. Tested on 200+ local businesses across six countries before opening the doors.
Free tier for one audit a month. Paid plans for history, alerts, and multi-site tracking. No funding rounds, no investor pressure. A useful tool.
