Both are good. But now if you already have a good targeted audience in Facebook, then this can be a really good advantage for you. Because better have a targeted audience which is following you weekly. You may present them easily other services you may provide. Google also is really good. But actually many companies are trying to build a social presence online and they are having followers. But with google, you may have good conversions and good traffic but not necessarily followers. Which can be difficult on a long run business.
Facebook ads and Google Ads are the powerful advertising platforms. However, I suggest you to choose which is better for your business, because they are two different platforms - Facebook is known as a social media, so you must ask your self some questions about your visitors.
April 2019: We just completed an audit for a client currently spending $100,000/month in Google Ads. They're also doing other advertising with other networks, but Google was what we were brought in to audit.
What did we find? $42,000 in wasted ad spend PER MONTH. The people who setup the campain didn't optimize it, didn't target their locations, and didn't pay attention to the words they were targeting or the competition.
The market is a Dog Toy market, which is heavily marketed by many people, but the fact that they're blowing nearly half their budget was an eye opening for them.
The money is now shifted into video marketing for Facebook and YouTube ads.
Google ads & facebook ads never seem to work for me. I have had my google ads up for two weeks and have gotten a lot of clicks but nothing to show for it. I find that google ads is just another way to blow countless dollars on nothing.
I could say the same about facebook as thats always been up for two weeks and has done nothing for me as of yet. Unless everyone is waiting for a special day to start following me or something like that.
