I need to put more time on my sites

I’m quite disappointed with my Adsense earnings this month. I dunno why it’s not giving me the results I’ve wanted. Hmmm… I know I’m a lot to blame for that since I have been busy and neglected focusing on housekeeping of my sites. Even the contents are not regularly posted like before. A lot of topics to be posted are still on my list. Getting an seo software could help but I also need to spice up my sites with valuable content to increase traffic and attract regular readers.
