What are the most common search engine optimization (SEO) mistakes appear on websites?
To find out, SEMRush used its site audit tool to collect anonymous data on 100,000 websites and 450 million web pages. The researchers examined how each site and each page performed in terms of search crawlability, technical SEO, speed and on-page SEO.
As part of the analysis, the researchers assigned each of the 40 most common SEO issues an impact score of between 1 (low severity) and 5 (high severity).
Two-thirds of the websites examined had duplicate content, one-third had broken internal links, and 23% had slow load times.
