I just want to do some basic changes like using keywords in Title and including site maps. I always believe that for getting top in Google we just need to put some keywords, a quality content and good backlinks. You are right that most of the information on the internet is outdated. Also there are many confusion among other Professional SEOs regarding different things. Like some say keyword density is not important and some say it should not be exceed more than 5%. I decided to listen all but use my common sense.
