Google Ads is an online advertising platform developed by Google, where advertisers bid to display brief advertisements, service offerings, product listings, or videos to web users. It can place ads both in the results of search engines like Google Search and on non-search websites, mobile apps, and videos.
Microsoft Advertising is a pay-per-click (PPC) advertising system. You bid based on how much you are willing to pay per each click on your ad. Because webpages have a limited number of places to show ads, we auction those spaces. You are bidding against other advertisers to get your ads into the space you want. So if you bid on the keyword "shoe", you will have to beat the bids of the other advertisers who are also bidding on "shoe." You determine how much you are willing to bid.
The difference between organic search vs. paid search is simple: it's the cost. While organic search focuses on unpaid rankings in search results, paid search focuses on paid rankings. With organic search, companies use SEO to optimize their site's visibility or rankings in search results.
