Search engine optimization refers to the way a person has to optimize a website in order to improve their placement in the search engine.
And that's done onpage and offpage, meaning without touching the website itself, but by working on others.
SEO stands for search engine optization Here , seo could be understood as a verb , not a noun . It means do some seo on a page/site so that the page/site can rank in the first page of SERP (search engine result page).
Appreciate all the replies, I think there is enough repeating. I would suggest to the OP why not do a search of the forum or go to Google or Wiki for definitions?
