It’s time to implement our knowledge from the first part of this two-part tutorial series. To give you a better handle on the process of keyword selection, we need to illustrate it with a case study. Keep reading as we walk through how to choose the right keywords for your Google AdWords campaign -- and actually start that campaign.
In our case study example, John registers the website www.repair-laptop.net. He is a certified and known laptops technician, who gained several years of hands-on experience with the top brands while working in Miami, Florida. He lost his day job at the height of the financial crisis and decided to start a business for which he can offer his services online.
Step 1: Optimize landing page performance
After completing his website with the help of website developers he hires, he optimizes the landing page and content according to two GoogleAdWords guides (which you can read at the links).
Now that the landing page (which he selected to be the home page) seems perfect and within guidelines, John takes a piece of paper and brainstorms possible keywords to target for his first Google AdWords campaign. Of course, the site is receiving virtually no traffic because it is new, and no SEO campaign has ever been conducted for it.
Step 2: Brainstorming Targeted Keywords
So John decided to launch an AdWords campaign to immediately send him targeted traffic to his site from Google's search engine and partner websites.
The following is the long list of possible keywords he selected during the brainstorming process (he decided to target an exact match since he needs it to appear relevant and specific):
Repair Laptops
Repair Laptops Miami
Repair laptops Florida
Cheap laptop repair
Cheap laptop repair Florida
Cheap laptop repair Miami
Laptop Repair
Laptop Repair Florida
Laptop Repair Miami
Affordable laptop repair
Affordable laptop repair Miami
Affordable laptop repair Florida
Since above appears generic; he also decided to dig deeper and brainstorm some of the popular laptop brands he can possibly target:
Dell laptop repair
Dell laptop repair Florida
Dell laptop repair Miami
HP laptop repair
HP laptop repair Florida
HP laptop repair Miami
Step 3: Determining the Budget and Pricing
John knows he did not have a massive budget to spend with his campaign, so he decides to limit his budget to something realistic. He decided to launch the campaign at first with a $5 daily budget. So his monthly budget is around = $5 x 30 = $150. Of course, to make a profit, the business should make more than $150 per month.
If he prices his service at $100 minimum per repair, he needs to have more than $150/$100 ~ 1 customer per month in order to make profit. But in order to support and make a decent living, he needs to attain more, so he decides to be careful with which keywords he is targeting.
