What is Keyword Research?
Keyword research is the process of finding and analyzing keywords and phrases related to your business, product, or service that people are searching for on search engines such as Google. The goal of keyword research is to understand what words and phrases your target audience is using to find information online and to determine the most valuable keywords to target in your marketing campaigns. By conducting keyword research, you can improve the relevance and targeting of your ads, increase website traffic, and ultimately drive more conversions and sales. Keyword research is an essential part of search engine optimization (SEO) and pay-per-click (PPC) advertising.

Best Practices
Brainstorming Keyword options
-
Identify all the possible product categories that you and your competitors have. Head over to their product pages and identify how many types of products they sell.
Run and analyze your competitor's strategy and research. Refer to SOP 009: How to Analyze Your Competitor’s Google Ads Strategy.
Iterate the keyword research process several times to get as many potential keywords as possible for your campaign.
Choose from the Keyword Planner recommendations
- Organize keywords into tightly-themed ad groups.
Example:
Ad Group = Yellow Snowboards
Keywords = “yellow snowboards”, “buy yellow snowboards”, “yellow snowboards for sale”, “cool yellow snowboards”
As you continue to iterate your keyword research process, it’s important to note how you want to structure your campaign and ad group. To do that, refer to SOP 050: How to Set Up Google Ads Campaign Account Structure.
- Forecast the potential and cost of the keywords from the Keyword Planner results
- From the main dashboard, click on Tools and settings.

- In the Planning section, select Keyword planner.

- Click Get search volume and forecast.

- Paste the keywords into the text field and click Get started.

-
Adjust the following metrics to get a forecast for your keywords.
-
Average daily budget - this is what you plan to spend daily for this set of keywords.
-
Conversion — Estimated conversion (%) on your sales/landing page. If you’re unsure what conversion rate to set, you should set up conversion tracking in Google Analytics following this guide SOP 074: Setting Up Google Analytics Conversion Goals. In the meantime add a fictional conversion rate (e.g. 3%) while you wait for the conversion data

- You will then get an estimated forecast based on your previous input. The following forecast is based on a $30 daily spend and 4% conversion rate.

7. You can then compare if the average cost per acquisition (Avg. CPA) is lower than your cost per conversion to determine the potential profits for this campaign. You can also adjust the forecast with a different daily ad budget and conversion rate before you decide if this set of keywords is worth running a campaign for.
Note: Always revisit the forecast based on real data after campaign launch. The forecast that you can from Google should only be used as an estimate since CPC, conversion rate, and CPA depend on a wide range of factors.
8. That’s it! You now have a set of grouped keywords to create a new campaign for!
