Open the campaign table and look at the Impr. column. It shows a zero or a dash, yet the status beside it says Eligible. Nothing is paused, the card is on file, and still no one has seen your ad. Eligible means Google is allowed to show the ad, not that any auction has picked it.
Searches for this exact problem are rare: about 10 a month, from 1 distinct query. So the cause is usually something specific to your account, not a known Google outage. Search volume, targeting and ad rank decide whether you appear, and you can check each one yourself.
Start with the keyword column, not the campaign status
The campaign status is only a summary; the keyword status tells you more. Open the Keywords tab and read the Status column for each row. A keyword marked Low search volume is not entering auctions at all, because Google judges that nobody is searching it often enough. This is common for very narrow phrases, such as a full street address, a model number or a long sentence copied from a customer email.
If most of your keywords carry that label, the problem is vocabulary, not bidding: your customers use different words than the ones you chose.
Match the symptom to the likely cause
| What you see | What it usually means | What to check next |
|---|---|---|
| Keyword status says Low search volume | Phrase is too narrow to enter auctions | Replace with the shorter wording customers actually type |
| Keywords are Eligible, but impressions stay at zero | Ad rank is too low to win, or match type is too tight | Look at the Search lost IS (rank) column and the match types |
| Ad status says Approved (limited) | A policy limit is restricting where the ad shows | Open the ad's policy details and fix the flagged text or page |
| Campaign is new and nothing has served yet | Ad review or early delivery lag | Confirm ads are approved, then let it run before changing anything |
| Impressions appear only for some locations or hours | Location or schedule settings are cutting off demand | Review the location and ad schedule reports |
| Search campaign works, but Performance Max or Demand Gen shows nothing | Assets are thin or audience signals are too restrictive | Check asset ratings and loosen the audience signals |
Check whether a negative keyword is cancelling your own keyword
Negative keywords are easy to forget about. A broad negative at the account or shared-list level can block the exact phrase you are bidding on. Open the Negative keywords view, check every level, and search for words that appear in your keyword list. One careless negative such as "free" or "cheap" can wipe out a small campaign that depends on only a handful of phrases.
Read the impression share report
If the keywords have no volume warnings, add the impression share columns to the table. They separate two situations that look identical from the outside. Lost to budget means the ad was eligible but the daily limit ran out. Lost to rank means the ad lost the auction on bid and quality. A rank loss on every keyword usually points to weak ad relevance or a landing page that doesn't match the search, not to a need for a bigger bid.
Look at who the campaign is allowed to reach
Audience settings can silently turn a Search campaign into a narrow one. If an audience segment is set to targeting instead of observation, only people on that list can see your ads. A small remarketing list may be too small to serve at all. Also check device adjustments, the network settings and the language setting. A language that doesn't match your customers' browser language will block people you wanted to reach.
Judge the idea before you spend more on it
Sometimes the honest answer is that the market for the phrase is small. A local service with a specialized offer may simply have few searchers each week. In that case, more bidding won't create demand. Broaden the wording, add closely related services, or choose a different channel for that offer. If you want a related view of the other failure mode, where impressions exist but nothing is spent, see the guide on Google Ads not spending.
What to do this week, and when a second pair of eyes pays off
Do these in order: read the keyword statuses, read the ad policy status, scan the negatives, then read the impression share columns. Keep a short note of what each step showed. If all four checks come back clean and the campaign is still silent, the cause is probably in how the account is structured or how conversions are measured. That is the point where a paid-advertising specialist can help. Many agencies, including ours, will review an account and tell you what they found before you commit to anything. If you can handle the checks above yourself, you may not need outside help at all.
