someone suggested that if you are a good seo, then you shouldn't get clients and promote their sites. you would do much better if you make and promote your own sites. This got me thinking...if this is true, then why do seo companies exist? so is this true or false? I think it's false. because for example, if I am promoting a plumber's site, I wouldn't want this to be my own site. I wouldnt want to be a plumber and learn how to install pipes and unclog the toilet. I would rather promote the site and leave the rest for the plumber to figure out.
