What is a good readability score for SEO articles?
Well in my opinion you should create articles as simple to understand as it can be. Hard to say what is good readability score because SEO is actually “guidelines rather than actual rules”.We don’t know exactly how Google search engine is working. Sometimes Google will give us some tips but that’s all.
Best example of SEO weirdness is that many websites are spending large money on backlinks, believing that it helps them rank better. When in reality John Mueller (Google Webmaster) said that paid backlinks are ignored.
