The "About Me" page is arguably the most important one on your blog. If you look at your stats, you'll see that it actually gets quite a lot of traffic; people want to know about you and who you are. If you want to work with brands or PRs, it's especially important to have a good "About Me" page, as this is the first place they will look to see whether they want to work with you.
Here are a few tips for constructing a good "About Me" page. First things first: there is no point whatsoever in writing yourself a lovely About page, publishing it, and then just never looking at it again. You need to regularly review your page and check whether all the information in it is still correct and relevant. If your About page says you're pregnant, but your child is clearly now a toddler, people will be confused as to what's going on.
