What a keyword cluster is

A keyword cluster is a group of keywords that share the same search intent. Instead of dumping every related keyword into one campaign, Hero Marketer groups keywords into intent based clusters and treats each cluster as the unit of campaign creation in the wizard. The wizard calls a keyword cluster a keyword group.

What search intent means​

Search intent is what a person tries to do when they type a query into Google. Two queries can sound similar and carry very different intent:

  • "Project management software", exploring options, early stage research.
  • "Project management software pricing", comparing prices, mid stage.
  • "Best project management software for engineering teams", narrowing for a specific use, mid to late stage.
  • "Alternative to jira", dissatisfied with a current tool, ready to switch.

Those four queries belong in different campaigns. They need different ad copy, often different landing pages, and they convert at very different rates. A keyword cluster groups queries that share one intent so a single campaign can serve them well.

Hero Marketer does not make one cluster for each stage of the funnel. It keeps only high intent keywords, the searches of people who are ready to compare, try, or buy. Then it groups those keywords by theme.

Why clusters beat flat keyword lists​

When you dump every keyword into one big campaign, you create three problems that a keyword cluster avoids:

  1. One ad cannot speak to multiple intents. An ad that works for "project management software" (broad, comparing options) will not work for "alternative to jira" (specific, looking to switch). One of them ends up mismatched.
  2. Bidding gets muddled. High intent keywords are worth more per click than low intent ones. A mixed campaign forces one bid across all of them. This leads to over bidding on low intent keywords or under bidding on high intent ones.
  3. Reporting gets unreadable. When you cannot separate which intent performs well, you cannot optimize. To pause the weak keywords and scale the strong ones, you need clean clusters.

Tight clusters let you write ad copy that matches the intent, bid appropriately for each, and read clean data per campaign.

How Hero Marketer builds clusters​

Hero Marketer builds clusters from four inputs:

  1. Your seed keyword. The search term that you type in the sentence on the Choose what to target step.
  2. Google Keyword Planner ideas for that seed. Related keywords for the country that you picked, with monthly searches and bid ranges.
  3. Your product name and the problem it solves. The first point of What problem does your product solve? in the product context. The other product context sections are not used.
  4. The search type. Category search, Brand search, or Competitor search.

Hero Marketer keeps only high intent keywords that fit the seed and the product. It groups them into 1 to 3 clusters of up to 10 keywords. In the wizard, each cluster is a card. On Search, the cards are under Choose a keyword group, with the number of keywords and the monthly searches. On Performance Max, they are under Choose a theme, and on Demand Gen, under Choose who sees your ad. The first card has the Suggested tag. On a Search campaign, the cluster that you pick sets the recommended monthly budget and the Expected clicks in the budget bar. These estimates are Hero Marketer's own, not Google's. Each keyword in the cluster shows its searches per month from Google. See How the recommended budget is calculated.

Keyword research in Hero AI uses the same high intent rules by default. It also follows your request, for example competitor terms or one segment, and it can return up to 6 clusters of up to 15 keywords. See Research keywords in chat.

What a good cluster looks like​

A good keyword cluster:

  • Has a clear, namable intent. "Alternative to jira" is a clear intent. "Stuff about software" is not.
  • Holds keywords with similar volume and competition. Wildly different volumes inside one cluster suggest the cluster is too broad.
  • Maps to one campaign and one ad copy direction. If different keywords in the cluster need very different ads, split the cluster.

What to do with the clusters​

Pick one cluster per campaign, and build a separate campaign for each cluster you want to target. One cluster per campaign keeps each campaign's intent tight, its ad copy matched to that intent, and its budget, bidding, and reporting clean.

Three clusters means three campaigns. That sounds like more work, but each campaign is fast to build through the wizard, and the clean separation pays off in performance and clarity later. To pick clusters in the wizard, see Choose keywords and budget.

When you are short on clusters​

Hero Marketer returns 1 to 3 clusters. One cluster is normal when few keywords pass the high intent filter. If the wizard returns thin or empty clusters, the seed keyword was probably too narrow, too brand specific, or not a phrase that a customer types. See No keyword clusters found for the fixes, in order.

How a cluster differs from a Google Ads ad group​

A keyword cluster sounds like Google's "ad group" concept, but they are not the same:

  • An ad group is Google's container inside a campaign. One campaign can hold multiple ad groups, each with its own keywords and ads.
  • A keyword cluster is Hero Marketer's organizing principle. The wizard maps one cluster to one campaign with one ad group, because that gives the cleanest behavior at the budget and performance levels.

Some Google Ads users prefer multi ad group campaigns. Hero Marketer keeps it simple by default: one cluster, one campaign, one ad group. If you want to evolve toward the multi ad group pattern after launch, you can do that in Google Ads directly.
