If someone has written any article and wants to increase traffic on the website. Does anyone have any idea how Facebook likes advertisement work? Is that worth investing money for facebook likes? What do we get if we have enough likes?
If the post isn't intended to make revenue other than AdSense then no it wouldn't be worth using FB's PPC service. If it's an affiliate product then it could be worth it depending on the ROI. You get nothing but a warm fuzzing feeling for having a lot of "likes".
You have to know the network or person very well! Learning the strategy is really not that hard and once you have it down you can repeat it day in and day out to build a fan base. Then you can outsource it and teach the person the way you do it and have them do it. Of course be open to learning from the person as well if they have value to give you.
You could at least try to create traffic in the network. It may be risk taking but an investment as well as part of your digital marketing strategies. Creating a fuzz on social networking sites like Facebook and Twitter may actually help you on creating a noise about your organization or the product/services. This also serves as an advertisement as it appears on everyone connected to the users who liked it. You could at least try and study the behavior and the effects. If you think it generates income and increases your ROI then it would be better.
There are some other tools that you can use to promote your facebook page free of cost, but you have to spend time on that. And if you want to spend money to get facebook likes you can use that way to promote your page and yeah worth it. Paid likes can get you some clients/ customers.
I'd recommend you to create a fan page and build audience .. its not just Facebook though you will have to create a mix of all social media sources ..
