Uh. Don’t listen to comment one. The keyword planner works but the numbers are estimates. Look for keywords with a click through rate of 4% or higher. 4% and above are often transactional, which means people are clicking to act. 10-100 volume is super super low. I try to look for a list of keywords that can generate at least a few thousand clicks a month. Then you decide how many you want to buy. The target ROAS is super tricky. The KW planner has NO WAY to know how well you will convert, which is why you put your conversion percentage in. If you don’t know, guess a 3% conv rate. You should target max conversion within your budget and your budget should be enough to buy at least 500 clicks. Preferably at least 500 clicks a month. At this minimum level you will see if you can sell your product. 500 clicks per month at 3% conv rate will take 3 months+ to get to 50 conversions. That’s a LONG time but your paying for those clicks so most new business won’t try. It takes 50 conversions for Google to begin proper conversion targeting, so you see how a certain volume of clicks and sales is necessary to start the machine. It’s a fantastic tool but no one will teach you how to use it. I had to run hundreds of ad tests to learn on my own. All you need is one good keyword if it has enough volume and it converts. Look for quality over quantity, especially if you don’t have a large budget. Pick 2-3 keywords for each of 2-3 ad groups. Write ads with those keywords in the ads, especially headline 1, and put those keywords on the landing page, especially in headline one. Then make the conversion process as smooth and easy as you can. Then sit back and don’t touch anything for 14 days. At the end of 14 days you will have some data. Take those numbers and try to improve. If you can’t afford ads, save until you have $1,000 a month for three months and try. God speed. Answer from gdaily on reddit.com
