You launched your campaign, but you are not getting the traffic you expected. Or worse, you are getting traffic, but it is from people looking for “free” stuff who will never buy from you. This usually happens because the wrong keywords were added to the wrong ad groups. It feels like throwing money into a black hole.

To add keywords to Google Ads, navigate to “Campaigns” in the left sidebar, select “Audiences, keywords, and content,” click “Search keywords,” and press the blue plus (+) button. However, simply adding words is not enough; you must select the correct “Match Type” (Broad, Phrase, or Exact) to ensure you are targeting qualified buyers and not just random searchers.

I will guide you through the technical steps of adding them and the strategic decisions of choosing the right ones.

How Do I Mechanically Add Keywords to an Existing Campaign?

Google changes its interface often, which makes simple tasks feel complicated. Here is the current, most direct method to add new terms to a running campaign.

Where Is the Keyword Entry Screen?

I log into my Google Ads account and look at the left-hand menu. I click on Campaigns, then expand the Audiences, keywords, and content section. From there, I click on Search keywords. I will see a list of my current keywords. To add new ones, I click the blue plus (+) button at the top of the table. Google will ask me to select a specific Ad Group. This is crucial: I never add keywords to the wrong Ad Group. If my Ad Group is about “Red Shoes,” I must only add keywords related to “Red Shoes.” If I add “Blue Boots” here, my ad copy will not match the user’s search, and my Quality Score will tank.

How Do I Input the List?

I can type the keywords manually, one per line. If I have a large list in Excel, I can copy and paste them directly into the box. Pro Tip: I never just type the words plain. I add special punctuation to define the “Match Type” immediately.

• keyword = Broad Match

• "keyword" = Phrase Match

• [keyword] = Exact Match I will explain why this punctuation is the difference between profit and loss in the next section.

Which Match Type Should I Choose?

This is where 90% of beginners lose money. Google defaults to “Broad Match,” which is often a trap for new advertisers.

Why Is Broad Match Often Dangerous?

If I type running shoes (no punctuation), this is Broad Match. Google will show my ad for “running shoes,” but also for “sneakers,” “marathon training,” and maybe even “tennis socks.” The algorithm decides what is “related.” While this brings in a lot of traffic, it is often low-quality. I use Broad Match only when I have a massive budget and use “Smart Bidding” strategies that can automatically filter out bad users. For most campaigns, I avoid it.

When Should I Use Phrase and Exact Match?

• Phrase Match (“running shoes”): I use quotes. This tells Google the user must type the phrase “running shoes” in that order, but they can add words before or after (e.g., “best running shoes for men”). This is my “sweet spot” for balancing volume and relevance.

• Exact Match ([running shoes]): I use brackets. This tells Google to only show my ad if the user types exactly “running shoes” or a very close variant. This has the lowest volume but the highest conversion rate. I use this for my most profitable, high-intent keywords.

How Do I Find the Right Keywords to Add?

I never guess what my customers are searching for. I let data tell me.

How Do I Use the Keyword Planner?

Before I add a keyword, I go to Tools and Settings > Planning > Keyword Planner. I select “Discover new keywords” and type in my main product. Google generates a list of hundreds of related terms. I look at two columns:

1. Avg. monthly searches: Is anyone actually searching for this?

2. Top of page bid: Is this keyword too expensive for me? I select the best opportunities from this list and add them directly to my plan.

How Can I Spy on Competitors’ Keywords?

I use the same Keyword Planner tool but select “Start with a website.” I paste my competitor’s URL. Google will scan their website and tell me the keywords they are likely targeting. This is a fantastic way to find gaps in my own strategy.

How Does Keyword Intent Affect Ad Creative?

Adding the keyword is only step one. The keyword tells me what the user wants, but my ad creative must deliver it.

Matching the Ad to the User’s Goal

If I add the keyword “buy crm software,” the intent is transactional. The user is ready to spend money. My ad should be direct: “Buy Best CRM – 20% Off.” If I add the keyword “how to manage customers,” the intent is informational. They are researching. A “Buy Now” ad will fail here. Instead, I need to offer value or education.

How Can Interactive Ads Capture Informational Traffic?

For those informational keywords (which are cheaper and have high volume), I need to engage the user, not just sell to them. I use Gamewheel to create interactive landing pages or ads for these specific keywords. For example, if the keyword is “which car should I buy,” I run an ad that leads to a “Car Finder Quiz” created with Gamewheel. Because the creative matches the “research” intent of the keyword, the user clicks and engages. I capture the lead through the quiz, rather than trying to force a sale immediately. By aligning my added keywords with the right type of interactive content, I can convert traffic that my competitors (who just use static sales pages) are losing.

Why Are Negative Keywords Just as Important?

Finally, adding keywords is not just about what you want; it is about what you don’t want.

How Do I Block Bad Traffic?

Every time I add a positive keyword, I think of the “negative” version. If I sell “luxury watches,” I add “luxury watches” as a keyword. But I immediately go to the Negative Keywords tab and add words like “cheap,” “replica,” “fake,” and “repair.” This ensures my ad never shows for “cheap luxury watches.” Managing my negative keyword list is actually more important for profitability than managing my positive list.

Conclusion

Adding keywords is a mechanical process, but choosing them is a strategic one. By using Phrase and Exact match, validating volume with Keyword Planner, and pairing high-level keywords with interactive content, you can build a campaign that drives sales, not just clicks.
