M-Flux V2 represents an evolution from the original M-Flux. Key differences include a wider array of metrics, decreased reliance on DA due to its susceptibility to manipulation, increased weighting for DR to reflect link profile strength, incorporation of insights from recent Google updates and data analysis, and a greater emphasis on topical relevance and user engagement factors. It also incorporates a 33-point human review to ensure quality is maintained. Essentially, M-Flux V2 is designed to provide a more balanced, accurate and up-to-date assessment of a website’s link building potential.
