Brand Guidelines are a fantastic resource for making sure everyone is on the same page when it comes to YOUR brand. They detail things like colour references and which fonts are to be used, ensuring you'll always have consistency throughout your marketing efforts. You can give your brand guidelines document to your graphic or web designer to make sure they know the best way to present your brand so that it's in keeping with everything else you've produced.
A detailed document will also include things like your brand personality, or tone of voice - the way you talk to your customers and present yourself is just as important to overall perception as how you look. Images and colours can also evoke very different feelings and emotions so there's lots to consider.
Remember - your branding is about so much more than just a logo!
