"My work may be garbage but it's good garbage." Mickey Spillane
One of the challenges of doing promotions on the web is the blog tour. There are many reputable places you can go to for good tours at reasonable prices. One that I cannot recommend enough is Orangeberry.
However, what is most typical of others who offer blog tours is what is happening right now with Cindy Franks-White at Phoenix Fire. She is getting a three blog tour (which she must pay for separately from the other things that PF charges their authors for) and all three of the blogs listed are just Tabetha Jones in clever plastic disguise.
When you go to someone for promotion, hired or volunteered, please check that they are a genuine company. There are just as many scam promoters as there are scam publishers. Google is your friend. The best way to check is to put in the following search phrase: “(company name) complaints.” You’ll be surprised at what comes up for most places.
