im new to this field of online marketing.
have done my basic research and have some basic beginner questions as usual :)
here they go:
what is the EXACT difference between when we "submit" a website url and when we "optimize" a website?
do all the pages of a website require "meta tags" for keywords or just the index page?
suppose, if i have 10 pages in a website, and i have added my meta search tags in all of these pages, and then i will go and submit my website URL for free through an online free submission website, will the results differ from actually hiring a company for SEO services?
what do these SEO companies actually do to add the website in top ranking?
will apreciate all the help you can offer, thanks :)
