adwords is most effective online advertising network. It can also turn out to worst if you dont know how to use advertising most effectively.
why not, it's very helpful for me, i can make more than 3k+ per month but maybe you'll get nothing at the beginning
It used to be useful when I had the account. Sadly, I've been banned for a year and a half and miss it.
it depend ! if your website selling a products, then Google Adwords is the best tools to get costumers/sales ! but if your website only giving a free stuff! then Adwords its not the best tools!
It's just a tool, like any other. When used properly it can increase your ROI. Otherwise it can cost you big-time. Make sure your landing pages are related to your ad. Test conversion rates and split-test different landing pages. Long tailed keywords are best.
In my opinion, Google AdWords is one of the useful tools to attract traffic on your website. You cover potential market and retell about your service/good only potential customers!
To my mind absolutely necessary to use the tool like Google AdWords because it allows to choose the best KeyWords to your site promotion!
