I really don't like weekends (Friday nights & Saturdays & Sundays) because my websites are not positioned as good as on weekdays, even I work harder on weekends in submitting to web directories and social bookmarking sites.
For example, during weekdays, my sites are on the second page on Google, but they are on 4th page on weekends.
I really don't know why these major search engines don't like my websites on weekends.
Any advice is appreciated.
Thank you for reading and have a lucky day!
