What they did
SearchPilot shortened the title tags on a travel site's search results pages by removing filler words such as 'Find' and 'Book' along with state names. They tested the shortened titles against the originals as a controlled split test so the change could be measured against a real control group.
What they found
The shorter titles produced an 11% uplift in organic traffic. Removing the extra words let dynamic pricing show in full in the search snippet, which turned out to be worth more than the keywords and location text that were cut.
How much weight to give it
As a controlled split test the 11% lift is a real measured outcome for this site, not a projection. It shows that what appears in the snippet can matter more than stuffing keywords into the title.
What it doesn't prove
It is one travel site, and the gain hinged on freeing room for live pricing in the snippet. On a site where the removed keywords help rankings or clicks, cutting them could just as easily lose traffic.
