getting top of the search result
Is there no google advertising method Which can locate our company's website or video on the top of the search result when people search specific key word??
If there is, I want to know about the price information.
Re: getting top of the search result
This is basically what AdWords does - however, it's not quite as straight forward as that.
Here's the bones of how it works. You identify a keyword that you think people will use when they are searching for your product or service. You bid on that keyword and tell Google how much you would be willing to pay for a click on your ad that would take the visitor (who searched for that particular keyword) to your site.
Of course, you are not the only person hoping to attract that searcher - all your competitors are also keen to catch the visitor - so to be top of the list you need to bid more than the rest.
And there 's another factor - Quality Score - which you will want to read up about. QS is a multiplier that Google apply to your bid based on just how relevant to the keyword your ad and landing page (the page visitors go to when they click on your ad) is compared to others. So, if you are highly relevant for that specific keyword you might appear above someone else who is not so relevant - even though you pay less for the click.
Take a look at the resources tab top and center of this page as a starting point.
