Our Verdict
For merchants primarily concerned with identifying and fixing broken links and 404 errors, Doc 404: Fix 404 links is the clear choice.

SEO On: AEO optimizer LLMs.txt is better suited for merchants looking for a broader SEO optimization strategy. It has a significantly higher review count, suggesting a more established user base and a potentially more comprehensive feature set, although the specific functionalities beyond AEO and LLMs.txt need further investigation. If you're experiencing significant problems with 404 errors, choosing Doc 404 first, then moving to SEO On makes sense.
