I have a home decor blog, however I don´t always have enough ideas on what to write. Where would you look for information on this topic? What is your favorite home decor topic? Thank you
I'd start with an informal reader survey. Talk to the "ideal" reader of your blog -- likely, you know these people personally. What questions do they have? What would they like answers to? What do they want to see more (or less) of?
Next, consider a formal reader survey. Michael Hyatt does a wonderful job and outlines his process here: http://michaelhyatt.com/tag/survey
I'm happy to help more. The answer to your question is right under your nose.
