Google Ads
The correct number of keywords is the number needed to cover meaningful search intent without creating a structure you cannot manage. A campaign with 500 keywords is not sophisticated because it has 500 keywords. A campaign with five is not automatically simple and efficient.
Keywords that should lead to the same ad message and landing page can often live together. Queries for "men's waterproof hiking boots" and "waterproof hiking boots for men" probably do not need separate campaigns just because the wording differs. A query for "hiking boot repair" represents a different intent and may not belong at all.
Close variants and broader intent matching mean advertisers no longer need every plural, word order and tiny spelling variation as a separate keyword. That makes query analysis and negative keyword management more important than keyword quantity.
If every small keyword theme has its own campaign, budget and ad group, conversion volume becomes thin and management becomes slower.
Putting every product category into one generic ad group makes it harder to align search, ad and landing page. Build the smallest structure that preserves meaningful differences in intent and economics.
If your Google Ads account contains hundreds of keywords and campaigns but very little clarity, send us an inquiry. We can consolidate it around the searches that actually sell.
