I try to post on various forums and post on twitter and my personal blog,apart from that most of the things we do are fine tuning our sites.
I do my to-do list every weekend and track it during the week. I like being structured and don't want to miss anything during the week.
I have a team of dedicated link builders who know what they're doing and all I do is tell them what keyword & anchor text to use
Check stats (earnings, rankings) Read related news, mark down important ones Write contents Build up links (once a week)
In free time i do concentrate on content. and i write uniquue articles. Directory listing is good for free time.
I am not planning on daily basis, for business plan i have sort out my timings in short or long terms.
After reading this thread, I am planning to create a Day Plan for myself so that my business can succeed.
I every friday make my plan what must be done next week, using rememberthemilk.com service and it works perfectly.
I try to spread the love a little bit. I don't want to be focused on one particular area. I write an article or two, submit to directories, stay active on relative forums, look for new places to advertise, work on improving the SEO on my own website by fixing any errors that show up in Webmaster Tools, etc.
