What It Is
Remarketing Lists for Search Ads, or RLSA, is a Google Ads feature that lets you adjust how your search ads behave for people who have already visited your website. You can bid more aggressively on those visitors, show them different ad copy, or target keywords you would not otherwise pay for, because you already know they are interested.
Why It Matters
For a local service business, RLSA is one of the cheapest ways to wring more leads out of an existing ad budget. Someone who visited your roofing site three days ago and then searches “best roofer” is a much warmer prospect than a cold searcher. RLSA lets you bid higher (say, $20 instead of $10 per click) for that returning visitor and still come out ahead because their conversion rate is typically 2 to 3 times the cold rate. It also lets you go after broader, more expensive keywords (like just “roofer”) only for people who already know who you are.
Common Misconception
RLSA is often confused with display remarketing (the banner ads that follow you around the internet). They are not the same. RLSA only affects search ads on Google, which means it only triggers when someone is actively typing a query. Display remarketing reaches people while they are reading, watching, or scrolling. Both have their place, and most local service businesses should be running both.
FAQ
How big does my remarketing list need to be for RLSA to work?
Google requires at least 1,000 active users in a remarketing list before it can be used on the search network. For a local business doing 5,000 to 10,000 monthly site visits, that threshold gets cleared in the first 30 to 60 days. Smaller sites need to wait longer or widen the list window (for example, anyone who visited in the last 180 days instead of 30).
Should I bid up on returning visitors or just exclude them?
Bid up. Excluding returning visitors is a mistake most account owners make once and never fix. People rarely convert on the first visit. They search, click around, leave, and come back later. RLSA is your tool for making sure you show up that second and third time, when they are closer to picking up the phone.
Can I use RLSA to show different ad copy to return visitors?
Yes, and it works well. Build a separate ad group targeting your RLSA audience and write ad copy that acknowledges the return (something like “Ready to book that estimate?” instead of “Top-Rated Local Plumber”). The familiar voice often lifts click-through rates by 20 to 40 percent over the cold-traffic version of the same ad.
