I want to do some guest posting on blogs that are relevant to my site. Where can I find them and how to approach the web masters? I want to find relevant blogs. Does anyone have a list?
Well, without knowing the topic of your site it's sort of hard to help you. I haven't seen a list like that, and I do get around the forums where you see lists of directories or followed blogs. But there are places like MyBlogGuest.com that put together bloggers with blogs that need content. I've been getting a lot of content from there. If lower quality works for you, there are places like fiverr where you can place a post on a relevant blog for $5. But have you tried searching '+relevantkeyword +"guest blog" ' and similar phrases? I just googled "real estate" "guest blog" (because I have some real estate clients) and found a great site that offers considerable resources for guest blogger wannabes: http://www.geekestateblog.com/real-estate-guest-blogging-resources/ including this list of suggested searches: That should get you started.
Just google for the niche/topic you are familiar with or wishing to write guest post on and choose the top most blogs in search results. All top most blogs with high pr will almost allow guest blogging.
