The SEOFactor report will be retired soon! As some of the checks are similar to the Payload/Assets audit, they are not needed.
Also, the SEO audits the homepage, which is not necessarilly relevant, especially the readability analysis. Most of the audited websites have simple homepages, image-heavy, or video-heavy, a paragraph or two of text and a call to action.
As a conclusion, from an SEO professional’s point of view, this audit is useless.
As a fun fact, this was the first audit implemented for SpeedFactor, refactored from an old utility tool.
