Google Ads Management Services That Optimise for Profit, Not Just Clicks

Agency management fees are commonly charged as a percentage of ad spend (typically 10–20%), a flat monthly retainer, or a hybrid of a base fee plus a performance element. Credex Media uses a flat retainer that scales in bands rather than a straight percentage, because a percentage fee rewards an agency for spending more of your money rather than spending it better. Ad spend is always paid by you directly to Google — we never resell media.

There is no universal good ROAS, because the number that matters depends entirely on your gross margin. A business with 70% margins can be highly profitable at 2.5× ROAS; a business with 25% margins loses money at 3×. The rule of thumb is that your break-even ROAS is one divided by your gross margin — so a 40% margin business breaks even at 2.5× and needs to clear that meaningfully to fund overheads and growth.

Expect three to four weeks for a restructured account to exit learning phases and produce stable data, and eight to twelve weeks before you can judge the programme fairly. Accounts with high conversion volume stabilise faster. Anyone promising transformation in the first fortnight is describing luck, not process.

Both, usually. Standard Search gives you control over high-intent branded and category terms and clean visibility of search queries. Performance Max is efficient for broad prospecting and Shopping inventory at scale. The common mistake is running PMax without brand exclusions, which lets it absorb traffic Search would have won anyway at a lower cost.

No. We work inside your account under agency access, which you grant and can revoke at any moment. The account, its history, its audiences and its conversion data belong to you permanently. This matters more than it sounds — an account's learning history is a genuine asset, and agencies that build campaigns inside their own MCC leave you starting from zero.

Yes, and roughly a third of our Google Ads clients are structured this way. A common split is that we own strategy, structure and the weekly optimisation cycle while your team owns creative production and landing pages. We document everything in a shared playbook so knowledge stays with you.

For search advertising in a competitive category we generally advise a minimum of around $1,500–$2,000 per month in media, because below that you cannot gather enough conversion data for automated bidding to work. In lower-cost markets and long-tail niches, less can be viable. We will tell you on the first call if your budget is too thin for the channel.

Google filters most invalid traffic automatically and credits it back, and for the vast majority of advertisers this is sufficient. Where we see genuine competitor-click patterns or bot activity in Display and Search Partners, we apply IP exclusions, tighten placement lists and, in serious cases, deploy third-party click-fraud tooling. We do not sell fraud protection as a scare-based upsell.
