The most obvious reason why there is limited data showing for your search is that each domain we track for the contact might not be doing anything with Google ads, the company might be focusing on SEO or contact marketing. If you know that they are advertising here are the reasons why you might not be seeing any data in Lead Kahuna;
 

1. They may only be advertising in a local market, targeting their ads to a specific location, a particular time of day, or demographic. Lead Kahuna takes it data from a neutral location, so our data is not overly influenced by local results. So if they are only getting a certain location, only IP addresses in that location will be shown the ads, this data we cannot see.
2. It's also possible that this company's ads only ran on highly niched keywords like a brand name or product-based keywords, that we don't currently search. Or they might be going after long-tail keywords
3. The company may only have a very small budget ie under 
4. $1000 or they have already hit their budget cap. This gives them a limited chance to appear on the general search because they are getting pushed out by domains with larger budgets 
5. Also, companies only appear on our results once they have been advertising for at least one month 
6. They are not advertising on Google ads which is the only source we pull data for, they may be focusing their budget on Bing, Facebook, display ads, youtube ads, etc
