I have a marketing blog that has been collecting dust for a few years. The blog has great SEO value and has been mentioned on alot of big sites over the years. I turned my focus away from it to grow another business, letting it go cold. Over the years it grew to about 4k monthly unique visitors with a 1k email list. It's been occupying mind - should I relaunch and commit to it or focus the energy elsewhere?
It depends on what you want to get out of re-investing your time in the blog. It's not about the traffic but whether it meets your goals - e.g. love for writing, business development, etc. The reality about blogging is doing it well takes time, effort and creativity so think hard before diving back in.
