Google has the most options and internet traffic when it comes to online advertising. Google has several key features that help a person manage, optimize, and otherwise succeed with an online advertising campaign. As mentioned in other articles Google allows a person or business to advertise a campaign to the search engines, content network and placement (link to other articles above) targeted areas. You can separate these features or combine them together.  Google allows graphic advertising through the content network and all placement advertising as well. Google analytics is a great feature that allows you to traffic the amount of traffic your website generates. You will receive information such as, visitors, page views, time the user spent on your site, see where your traffic is being generated from, a graph with day by day stats, and much more. With Google you can also track your ad campaigns and groups by reviewing the amount of impressions all the way through to how many clicks and conversions your ad campaign is receiving. If you are receiving over 200 conversions per month you also have the option to bid per conversion which is a complete new feature only offered by Google at this time. Google has more tools for their AdWords account than any other search engine, and of course they should, they are the biggest giant out there.
