I know, I know, this is a basic SEO question – the absolute URLs versus relative URLs. But we covered it literally 10 years ago and back then Google’s John Mueller answered the question and also answered it today. In short, both times he said for search and SEO, using one or the other technically do not matter. But the way he answered it back 10 years ago in a forum thread was in much longer form, suggesting relative URLs are easier for ongoing purposes (not for SEO) than absolute URLs. The way he answered it today was on Twitter, so much shorter form and said it doesn’t matter for SEO – which is true.
