Traffic Analysis for SaaS Acquisitions: Beyond the Surface Numbers

Traffic analysis is the most underrated part of SaaS due diligence. Sellers share Stripe dashboards readily but often guard their analytics. There's usually a reason for that.

Why traffic matters more than you think. For most SaaS products, there's a 3-6 month lag between traffic changes and revenue impact. A decline in organic traffic today means lower signups next quarter, which means lower MRR in 6 months. If you're buying based on current MRR without checking traffic trends, you might be buying at the peak.

Source diversification. This is the single most important traffic metric. If 60%+ of traffic comes from one source, you have a concentration risk. Google algorithm updates can cut organic traffic by 40% overnight. A paid channel getting more expensive can make customer acquisition unprofitable. Referral traffic from a single partner can disappear if that partner changes strategy.

Healthy distribution looks like: 30-50% organic search, 15-25% direct, 10-20% referral, 10-15% content/social, and the remainder from other channels. No single channel above 50%.

Spotting manufactured traffic. Some sellers inflate traffic before listing. Watch for: sudden spikes in direct traffic (could be bot traffic or purchased visitors), referral traffic from suspicious domains, social traffic from accounts created recently. Cross-reference traffic claims with independent tools like SimilarWeb or SEMrush estimates.

The analytics verification process. Ask the seller for Google Analytics or equivalent read-only access. Check at minimum: traffic trend over 12 months (not just the best quarter), traffic by source with month-over-month changes, conversion rate from visitor to signup, conversion rate from signup to paid, and geographic distribution.

SEO-specific checks. If organic search is a major traffic source, dig deeper. What keywords drive traffic? Are they branded or generic? Is the domain authority growing or declining? Have there been any manual actions or algorithmic penalties? Is the content strategy sustainable or was it a one-time effort?

The revenue-traffic correlation. Map traffic trends against revenue trends. They should generally correlate with the expected lag. If MRR is growing but traffic is flat or declining, the growth is coming from expansion revenue (good) or price increases (check churn impact). If traffic is growing but MRR is flat, the conversion funnel has a problem.
