The letters SEO stand for Search Engine Optimizer according to google Others call it Search Engine Optimization. The conclusion is that we can optimize search engines. Because we cannot do this, it really means Web Page Optimization. We can only optimize our own WEB PAGES in order to get higher search engine rankings.
