Nothing looks sloppier than websites that don’t abide by any sort of style guide. Is your blog section a complete deviation from your website? If so, this very well could throw off your visitors and decrease engagement. Instead, make sure that all of your web pages are consistent in design, font and even voice. For instance, if you use a very formal tone on your homepage, but a super casual tone in your blog posts, this could highlight brand inconsistency.
