Blog design - I am obsessed with blog designs as you can tell with my ever changing design and my shop but a blog design I think is so powerful when it comes to a blog. The design aside from the images is the first thing you will see and make a judgement on. If the design has 50 different colours and fonts plus a disorganised sidebar you will most likely not follow even if the content is worth the read.
Images - the pictures are the second thing I look for when I come across a blog. There's nothing better than to be presented with large and clear images. When I see photos on a blog that I love I will also give them a follow. I am very into photography so it matters a lot to me and in a silly kind of way makes me happy when I see a photo I like.
Content - whilst I love ascetics if the writing isn't any good I will more than likey not return to the blog or give them an unfollow ( I'm aware of how bad that sounds but honesty is the best policy, right ? ) I don't mind a few spelling or grammar mistakes. I know some people hate that and yes I don't like too many but when you see a few on an amazing blog it shows that there only human too and can make mistakes even if their blog to look at is perfect.
Advice posts - I love reading beauty but a change is good and I love getting advice and tips from other bloggers on how it has helped their blog or life. These are definantly my favourite kind of posts.
Interaction - I love it when a blogger reply's to the comments that are left on their blog. I think it's only really manners especially if someone takes the time to leave a comment.
