Launching a campaign is not the end of the work. The first 2 weeks are when most problems surface and when early signals tell you whether your message and audience are working. This article covers what to monitor, how to read the signals, and what to do when things are not working.
In this article:
Understand what to expect in the first 14 days after launch.
Monitor the right metrics at each stage.
Diagnose and fix the most common campaign problems.

Before you start
Complete the previous steps of retargeting your Growth Hub visitors:
What to expect in the first 14 days
Do not judge a campaign in the first few days. New campaigns go through a learning phase, and early data is often misleading.
At the beginning, focus on the basics:
Audience size growth
Impressions
Clicks and CTR
Landing page sessions from the campaign
view_item, begin_checkout, purchase, and generate_lead
Cost per conversion
Conversion rate from click to booking or lead
Here is what a normal launch looks like.
Days | What is normal |
1 to 3 | The audience is still building. Low or zero impressions. This is expected for new campaigns and new audiences. |
4 to 7 | The campaign starts delivering. First impressions and clicks appear. Conversion data may still be absent. |
7 to 14 | First conversions should appear if the setup is correct. CTR stabilizes. Enough data to make first adjustments. |
Do not make changes in the first 7 days. Google's algorithm needs at least 7 days of data to exit the learning phase. Pausing, changing bids, or swapping audiences before this resets learning and slows down results.
What to monitor and when
Focus on different metrics at different stages. Checking the conversion rate on day 2 is meaningless. Checking audience size in week 3 when you have no impressions is where to start.
Metric | What it tells you | Action if it looks wrong |
Audience size | Whether the campaign can serve at all | If below 100 active users, switch to a broader audience ( |
Impressions | Whether ads are being shown | Zero impressions = audience size or targeting issue, not a creative problem |
CTR (click-through rate) | Whether your creative is engaging | Low CTR = try stronger headlines or better images |
Landing page sessions | Whether clicks are reaching your booking page | No sessions = UTM or redirect issue on the final URL |
Conversions | Whether clicks are turning into bookings | Clicks but no conversions = landing page or pricing issue, not an ads issue |
Cost per conversion | Whether the campaign is efficient | High cost per conversion = audience is too broad, or the creative is not resonating |
Diagnose and fix common problems
Here are some common problems and how to diagnose and fix them:
No impressions
Check in this order:
Go to Google Ads > Tools and Settings > Audience Manager > Your Data Segments. Check the active user count for your audience. If it shows fewer than 100 active users in the last 30 days, the campaign cannot serve.
If the audience is too small, switch to the
view_itemaudience that accumulates users faster. Or extend your membership duration from 14 days to 30 or 60 days.Check that the campaign status is Active and that the budget has not been exhausted.
Low clicks or low CTR
The ads are showing but not being clicked. This is a creative problem, not an audience problem.
Test new headlines. Specific messages outperform generic ones. "Your meeting room booking is still saved" outperforms "Book coworking space today" for a
begin_checkoutaudience.Upload new images. Use clean, single-subject workspace photos. Avoid collages, overlaid text, and logos on the image.
Add an offer or urgency if appropriate. For example, "Check availability for this week" or "Spaces still available for Tuesday".
Clicks but no conversions
This is not an ad problem. The campaign is working. The issue is on your landing page or booking flow.
Check that the final URL goes to the correct booking page, not your homepage.
Test the booking flow yourself from the exact URL in the ad.
Check whether GA4 is recording purchase events after a test booking. If not, there may be a tracking issue on the confirmation page.
Review pricing clarity on the landing page. If the price is not visible before checkout, visitors drop off.
Clicks but no conversions is a landing page problem. Do not change your targeting or budget when this happens. The ads are doing their job. Fix the booking page first, then reassess the conversion rate.
Build your reporting view
Set up a simple view across GA4 and Google Ads so you can quickly check performance without pulling data from multiple sources.
GA4: Traffic acquisition report
In GA4, go to Reports > Acquisition > Traffic Acquisition.
Change the primary dimension to Session Source / Medium.
Add a secondary dimension: Click ➕ > Add > Session Campaign.
Customize the report to include:

Engaged Sessions
Key Events (conversions)
Revenue (if passing purchase values)
Save the report.
Your retargeting campaign will appear as google / cpc with the campaign name you set in Google Ads.
Google Ads: Campaign performance view
In Google Ads, go to Campaigns > your retargeting campaign.
Click Columns > Modify Columns.

Impressions
Clicks
CTR
Cost
Conversions
Cost per Conversion
Conversion Value
Optionally add:
All Conversions
Conversion Rate
Click Apply and save the column set.
Best practices
Set up your reporting view before you launch, not after. You want a baseline from day 1. Trying to build a report after a week of data means you are already behind.
Check audience size weekly for the first month. Audiences grow as more users visit your site. An audience that was too small at launch may reach its minimum size within 2 to 3 weeks.
Do not optimize too frequently. Check performance every 3 to 5 days minimum. Daily changes prevent Google's algorithm from learning and make it harder to identify what is actually working.
Keep a change log. Note the date and nature of every change you make. When you see a performance shift in the data, you need to know what changed to understand why.
Frequently asked questions
The campaign ran for 2 weeks, but I have no conversions. What should I do?
The campaign ran for 2 weeks, but I have no conversions. What should I do?
Work through the diagnostic chain. First check impressions: if zero, the audience is too small. If impressions are healthy, check CTR: if very low, the creative is the problem. If CTR is reasonable but no conversions, test the landing page manually. Trace the journey from ad click to confirmation page and check that purchase events are firing in GA4 Realtime.
GA4 is not showing traffic from my campaign. What do I check?
GA4 is not showing traffic from my campaign. What do I check?
Check your final URL UTM parameters first. If UTMs are missing or malformed, GA4 cannot attribute the session to the campaign. Use the Google Campaign URL Builder to regenerate the tagged URL and update it in Google Ads. Allow 24 hours for GA4 to process the data after making the change.
When should I expand from 1 audience to 2 or 3?
When should I expand from 1 audience to 2 or 3?
Expand when your first campaign is generating consistent conversions, and you have enough data to know what is working. For most operators, this means at least 10 to 20 conversions on the first campaign before launching a second. Running too many campaigns too early splits your budget and slows learning for all of them.
Should I pause the campaign when I am out of available spaces?
Should I pause the campaign when I am out of available spaces?
Yes. If your space is fully booked for the next 2 weeks, pause the campaign to avoid paying for clicks that cannot convert. Resume it when availability opens up. This is especially relevant for event space operators with specific high-demand dates.
