So, What are the advantages of paid online advertising over organic traffic ? This is the question that may have crept in your mind at times, as to why pay money for traffic when you can do SEO and get targeted traffic for free? In my opinion, there are many advantages. Lets take a look at few of those 
1. Paid Advertising gives you the option of getting traffic right from the word go. You can start having traffic in 10 minutes, that too highly targeted. This is something which is not possible using SEO (which may take weeks/months to show results).
2. Paid advertising can actually be used to know which keywords are actually brining sales/leads and then you can start optimizing for those keywords only rather than wasting time on keywords which are non-performing.
3. With Paid advertising, you can get traffic from places you want. You can target USA cities, different countries etc based on your business and services. This is something which might not be possible using SE traffic.
4. Also, Paid Advertising has this huge advantage over SE traffic, which is, Google’s algorithm changes every day. It can get difficult and annoying to keep up with all the changes and retain your rankings. There is always this risk of disappearing from first page or losing your positions in Google. But with paid advertising, there is nothing like it. As long as you have the money, your content is quality and your QS is good, you can continue advertising and making money.
5. Paid advertising instantly puts you on top of your game, leaving all your competitors behind in matter of minutes.
These are just some of the reasons and advantages which I thought you must consider as you advertise online.
