Why Your Google Ads Account Is Spending More and Converting Less

Accounts rarely fail suddenly. They drift. Spend climbs a little each month, conversions flatten, and by the time someone notices, the cost per enquiry has doubled and nobody can point to the change that caused it. Usually there was no single change. There were six small ones.

Here is where to look, roughly in the order that finds problems fastest.

Read the search terms report first

Not your keywords - the actual queries that triggered your ads. Broad match and the platform's own matching logic have both become far more liberal about what counts as related, which means an account left alone will steadily accumulate traffic from queries you would never have bought.

Sort by cost, look at the top fifty queries with no conversions, and be honest about how many of them describe a buyer. Job seekers, students, people looking for free versions, people in cities you do not service, competitors' brand names, and the merely curious all end up in there. Every one of them is spend that never had a chance.

Check what your budget shifted onto

If you run several campaigns, look at how spend has redistributed over six months rather than what it is today. Automated bidding will happily concentrate budget on whatever converts most easily, which sounds sensible until you notice that "easiest conversion" often means your cheapest, least valuable enquiry type, or your brand terms that would have converted anyway.

An account can look healthy on total conversions while quietly abandoning the campaigns that produce real revenue.

Confirm your conversions still mean something

Conversion counts inflate. Someone adds a phone-click goal, then a form submit, then a newsletter signup, then an event on the contact page load, and now one enquiry can fire three conversions. Meanwhile the bidding algorithm optimises towards whatever is most abundant.

Audit the list. Decide which single action represents a real enquiry, make that the primary conversion, and demote the rest to secondary. Accounts frequently improve immediately after this, not because anything changed in the market but because the algorithm was finally told what to aim at.

Look at where the clicks land

Cost per click rising is often less damaging than landing page quality falling. Check load speed on mobile, whether the page answers the query the ad promised, and whether the form asks for more than a first enquiry needs. A page that converted at a reasonable rate two years ago may have accumulated a cookie banner, a chat widget, a video and three extra form fields since.

Small friction compounds. There are practical strategies for tightening this up in this guide to increasing inbound leads, several of which apply directly to paid landing pages.

Account for competitors you cannot see

Sometimes the account has not degraded at all - the auction has. A well-funded competitor entering your category raises everyone's costs. You will see this as rising cost per click across the board with stable click-through and conversion rates, which is a different diagnosis to anything internal.

The response is not to bid harder into an unwinnable auction. It is to narrow onto the query segments where you have a genuine advantage, and to accept lower volume at a workable cost rather than matching volume at a bad one.

Rebuild the reporting so this cannot creep back

Most of the drift above is invisible on a dashboard showing clicks, impressions and total conversions. Build a view that shows cost per qualified enquiry by campaign, month over month, with spend distribution alongside it. Drift becomes obvious when you can see it.

If nobody internally has time to look at that weekly, that is a legitimate reason to hand it to a Google Ads agency like SIXGUN rather than letting the account run on automation and hope. The platform will always spend the budget. Whether it spends it well is a decision someone has to keep making.

Expect to cut before you grow

Almost every recovery starts with spending less. Strip the wasted queries, consolidate onto what works, prove the cost per enquiry at lower volume, then scale from a base you trust. Adding budget to an account that is leaking just funds the leak.
