Content site with ad revenue due diligence

Due diligence on a content site with ad revenue centres on getting direct, unfiltered access to analytics and ad-network history rather than accepting seller-prepared summaries, because the entire value of the business is a search ranking and an ad account that both need to be verified independently.

Reviewed

Diligence on a content site is less about deciding whether the opportunity is attractive — that judgment should already be made by the time an LOI is signed — and more about confirming, with direct evidence, that the traffic and revenue represented during negotiations are real, current and likely to persist. Because the site’s value is entirely intangible, the standard of verification here has to be higher than a seller’s own summary.

Get direct access, not summaries

Request direct login or read access to search-console data, analytics and the ad-network dashboard, covering the site’s full operating history rather than an exported spreadsheet or a set of screenshots the seller has selected. A seller who declines direct access once an LOI is already signed, at the stage where trust between the parties should be highest, is itself a signal worth pausing on rather than pushing past.

What a compliance review actually covers here

Confirm how the site handles PIPEDA obligations around analytics and advertising cookies, and, for a site with meaningful Quebec visitor traffic, whether Quebec’s Law 25 requirements have been addressed as well. Check whether the site’s own content makes product or service claims that could raise exposure under the Competition Act’s misleading-representations provisions. And confirm whether the site operates an email list at all — anti-spam obligations only apply if it does, and a site with no list carries meaningfully less regulatory review at this stage than one that does.

Auditing the content and backlink profile

Check whether content was produced with undisclosed AI generation at a volume or quality that would put the site at risk under a content-quality algorithm update, since this is rarely something a seller volunteers proactively. Run an independent backlink audit rather than accepting the seller’s account of how the site’s link profile was built, because paid or low-quality links are one of the more common undisclosed liabilities in this sub-sector, and they can trigger the exact kind of ranking risk the buyer is trying to price.

Reconciling ad-network payouts against bank records

Ad-network dashboards can be edited or misrepresented more easily than a bank statement, so it is worth reconciling the payout figures the seller has shown against the actual deposits landing in the business’s bank account over the same period, month by month rather than as a single trailing total. A mismatch does not automatically mean anything improper — networks sometimes pay on a delay — but any gap that is not readily explained deserves a direct answer before the buyer relies on the dashboard figures for pricing or financing.

Reading the site the way a buyer would, not just its numbers

Independently reading a representative sample of the published content is worth doing again at the diligence stage, not only earlier, because it is the only check that catches quality problems a seller’s own summary would never surface — inconsistent editorial standards, factual errors, or a pattern of thin articles clustered around whichever topics happen to earn the most per page view. This matters because search engines increasingly weigh exactly these kinds of content-quality signals, and a spreadsheet of traffic numbers cannot show any of them.

Confirming ownership of the content and any registered trademark

Where freelance writers or contractors produced the site’s content, confirm the underlying agreements actually assign ownership of that work to the business being sold, rather than leaving it with the individual contributor, since a gap here can leave a buyer owning a site full of content it does not fully own the rights to reuse or monetize. The same applies to any trademark in the site’s brand name — confirm whether it is registered, and if so, that the registration sits in the selling entity’s name and can be assigned as part of the transaction rather than left behind with the seller personally.

Confirming what actually transfers

The domain, the published content and its ranking history, the ad-network account subject to that network’s own approval, any registered trademark in the site’s brand, and analytics access itself are the things a buyer is genuinely acquiring. Search ranking is not among them in any contractual sense — no clause in a purchase agreement assigns a position in search results, so this part of diligence is about underwriting the likelihood ranking persists, not confirming a guaranteed transfer the way a lease assignment or an equipment bill of sale would be.

Findings that end deals

An undisclosed algorithm-update traffic drop, surfacing only once full analytics are finally reviewed, is the clearest deal-ending finding in this sub-sector. The ad network declining to approve the buyer, or the site failing to meet its current premium eligibility criteria, is a close second, since it can undercut the revenue basis of the entire deal. A meaningful share of backlinks traced to low-quality or paid sources, and AI-generated content at a volume or quality inconsistent with what was represented, round out the findings most likely to reopen negotiations or end them.
