Google Ads can produce some of the most valuable leads available to a Chennai business — because the person clicking your ad is actively searching for what you offer right now. That intent is what makes the channel worth paying for.

It is also what makes it unforgiving. Running Google Ads badly is one of the most efficient ways to spend money with nothing to show for it, and the difference between the two outcomes shows up as a cost per lead of ₹1,500 versus ₹12,000 for the same service in the same city.

Three problems account for most of that gap, and none of them are solved by increasing the budget.

The wrong landing page. Someone searches AC repair in Chennai and clicks your ad. They land on your homepage, which talks about your company history and lists eleven services. If your homepage does not answer all three questions immediately — do you do this, do you cover my area, how fast can you come — they click back and call your competitor.

Broad match keywords that drain budget. Google Ads on broad match settings will show your ad for searches that are tangentially related to your keywords. Tight keyword matching — phrase match and exact match with comprehensive negative keyword lists — is what separates efficient Google Ads accounts from wasteful ones.

Missing conversion tracking. If you are running Google Ads without conversion tracking set up for phone calls, form submissions, and WhatsApp clicks, you are flying blind. You cannot optimise toward outcomes you are not recording.
