How Stackmerit scores software
Most software reviews chase the longest feature list. We read each tool's own documentation and pricing page, weigh it against what verified users report, and score it on a fixed five-part rubric, so a score means the same thing across the site.
- Data qualityThe size and freshness of what a tool actually measures
- Feature depthHow far the toolset goes once the obvious jobs are done
- UsabilityHow long a new user spends finding things
- ValueWhat the plan costs once its limits bite
- SupportWhat verified users report when something breaks
Our review method sets out the five sub-scores, the sources behind each one, and where AI does and does not come into the work. Jake Harris sets every score, and his background is on the about page.
What is Stackmerit?
Stackmerit is an independent review site for SEO, AI visibility, email marketing and hosting software, written by Jake Harris and online since June 2026. Every tool is scored on the same five-part rubric, built from the vendor's own documentation, dated pricing and publicly available user reviews. We do not run first-hand product trials, and every review says so.
