I have been around book blogging for a long time. I started this one in 2006, but didn't post really regularly until about 5 years ago. It still ebbs and flows, but I have also seen a lot of blogs come and go during that time. If you are starting one or thinking of starting one here are some things to think about. (I have done a post like this before but not for awhile and I have more!)
I started mine as a way to keep track of what I read. Seriously, when I started it was just a list of books. Then I discovered the world of book blogging and decided to up my content a bit. When you are first getting started try and post four to five times a week. Seriously, if you have something new everyday on someone's feed they are more likely to check one or two of them out.
Page views and followers are important but NOT VITAL. I know my blog itself doesn't get tons of views, but I have some loyal readers. I do promote myself and my blog a bunch, but still not as much as I could. I tweet my posts and send links to publishers. I should start just a blog instagram but I haven't, I have a personal one that I use to post about books and a library one. I truly feel like promotion is key. If a publisher gets you a book do what you can to get the word out about that book.
(Just so you know, I know that I get a lot more privileges because I am also a middle school librarian, so if I had ever felt like I wasn't getting the word out enough I would have done more.)
You will probably get ARCs, but it might take a long time. I am at the point now were I get ARCs and finished books in the mail a lot. Not everyday or every week but more than I need. This is something I struggled with because I want to read and review everything I get but I still have books in my school collection and just others that catch my interest. So my rule of thumb is if I request it and get a copy, I read and review it. On both my Edelweiss and NetGalley profiles I am very upfront about letting publishers know I might not get them read, but I like to "flip" through every egalley I get approved for so I can see if it would be right for my library and the ages of kids I work with.
Sometimes I get surprise books and I don't feel as bad about not reviewing those. But I normally do a post about getting them (some call it Staking the Shelves, some call it In My Mailbox, I call mine Added to the List) and a thank you tweet to the publisher or person who sent it my way.
It can be overwhelming and a lot of work. I went through a time where I posted something every day. I tried a lot of different things to see if they would catch on, and sometimes they would, sometimes they wouldn't. I am just not the type to go and comment on other people's blogs for the sake of commenting or to get them to come and comment on mine. I also don't follow blogs anymore unless I really like them. I also take breaks. This has become more important as my life has gotten busier.
There was a time when I wold see a new book blog pop up everyday. I am a little out of touch with that part so I don't know if that is the case anymore but I know that if you have just started know that it takes time and patience. Enjoy telling people about awesome books and have fun with blogging!
