Hi. I have a question regarding to SEO of Google. I often use Google Korea. When I search particular keyword, I can see link on the upper section which can move to specific website as same red highlight part on this picture. When it comes to that picture, I searched ?Travel Hochiminh? on google however linked specific website regarding to ?Hochiminh tour? on the top. But that site doesn?t do ?Search Engine Optimization? at all. how can I do ?Search Engine Optimization? like that? I really want to know so I need your help.
