We Audited 50 PE Portfolio Websites. Here’s What We Found.
We audited 50 Midwest PE-backed portfolio company websites. Traffic, keywords, technical health, brand alignment. Most are invisible to search. A few are growing fast. The difference isn't luck, it's whether strategy was baked in from the start and what teams did after launch.
50 Midwest PE portcos with complete data. One chart.
Some grew. Some held steady. Some lost everything. The difference is visible from the outside.
Each column represents one portco. Values are % change in estimated monthly organic traffic (Ahrefs) between April 2024 and March 2026.

A new portco website usually takes one of two paths. The data explains what leads to each.
Across our audit, site rebuilds and post-acquisition rebrands produced different outcomes. Some drove meaningful growth. Others triggered severe, lasting declines. Middle ground was rare.
The rebuilds that grew shared a pattern: a clear brand narrative after the deal, ongoing content investment, and SEO fundamentals that carried on well after launch.
This isn’t a warning against rebuilds. It’s a diagnosis of which side of the split you’re likely to land on — and the diagnosis is visible before any code is written.
The question isn’t whether to rebuild. It’s whether the rebuild is treated like a box to check or a strategic foundation for portco growth.
A pattern observed in our sample
One services company in the dataset: four years of steady organic growth through the early hold period. A new site launched in April 2025 — a full platform migration with new URL structure. Four months later, organic traffic had dropped 92% from its pre-launch peak. Twelve months later, no meaningful recovery. This company is not an Atomicdust client; we audited its performance externally.
Four years of steady organic growth during the early hold period. Site ranks for 25,000+ keywords. Traffic trajectory: positive and stable.
New site goes live. Full platform migration with new URL structure. Traffic appears stable in the first 30 days while Google reprocesses the index.
Traffic hits peak at 50,810 visits/month — old URLs still indexed during the transition window. This is the last green month.
Oct 2025
Google completes reprocessing of the migration. Traffic drops from 50,810 → 22,000 (Jul) → 11,000 (Sep). Top-10 keyword rankings cut by 80%+.
12 months post-launch. Traffic at 4,210/month. No meaningful recovery trajectory. Site remains live in its post-launch form.
The portcos that grew through transitions treated the website as a strategic asset — not a launch deliverable.
Atomicdust is a St. Louis brand and digital agency. We've built and migrated 100+ websites for B2B and PE-backed companies.What we see across 50 PE portco websites.
We pulled publicly available keyword and traffic history on 50 Midwest PE-backed portcos, cross-referenced site changes against archive snapshots, and ran live audits on each site's current state. The pattern is clear: outcomes diverge sharply between portcos that treated the site as a strategic asset and those that didn't.
The tables and charts below present the range of outcomes we observed — not as warnings, but as a diagnostic. Every pattern below is something we can identify on a portco's site before any rebuild begins.
| Portco Type | Rebuild Period | Traffic Δ | What we observed |
|---|---|---|---|
Home Services Company Midwest PE-backed | Apr 2025 | −92% | Platform migration with new URL structure. Traffic held for 3 months then collapsed. 12 months later: no recovery. |
Consumer Outdoor Brand Midwest PE-backed | Mar 2026 | −66% | URL restructure during platform migration. Keyword footprint reduced alongside traffic. Recent event — still unfolding. |
Multi-Location Healthcare Midwest PE-backed | Aug 2022 + 2023 | −71% | Two rebuilds inside 12 months. 3.5+ years later, still well below pre-rebuild baseline. Compounding rebuilds compound damage. |
Residential Services Midwest PE-backed | May 2024 | −59% | Significant content reduction at rebuild. Top-10 keywords cut in half. Pattern: fewer pages, thinner content, weaker signals. |
Consumer Services Midwest PE-backed | Feb 2025 | −42% | Second rebuild in 4 years. Each rebuild fragmented keyword coverage. Pattern we see across repeat rebuilds without SEO continuity. |
Industrial Services Rebrand Midwest PE-backed | Late 2025 | +24% | Recent rebrand with SEO continuity built in. Traffic and top-10 keywords both growing. PE owner disclosed on site. |
IT Services Rebrand Midwest PE-backed | Jan 2025 | +100% | Full name-change rebrand. Top-10 keyword footprint doubled through the transition. Traffic near all-time high. |
Lawn Services Company Midwest PE-backed | Ongoing | +60% | Consistent content investment. Traffic growing significantly. Top-10 keywords nearly doubled over the window. |

A healthcare portco where rankings haven't recovered in 3.5 years.
One portco in our audit is a multi-location healthcare provider. For their patients, organic search is a primary pathway to care. Local location pages ranking in the top three on Google drove a meaningful share of patient acquisition.
The site built up gradually from 2018 through mid-2022, adding location pages, treatment content, clinician profiles. At peak, it ranked for 25,000+ keywords. Then two rebuilds happened within twelve months.
For a healthcare provider, every location page that loses its first-page ranking is a local market where patients are now finding a competitor. The rebuild didn't just cost traffic, it redirected patient flow. Recovery, where it happens at all, takes years.
The two consecutive rebuilds, August 2022 and April 2023, compounded each other. The first reduced page count and URL coverage. The second reinforced the reduction before Google could rebuild trust in the new structure.
Ahrefs Traffic Value is a modeled estimate representing what equivalent traffic would cost to acquire via paid search at current CPCs. Not a measure of actual revenue impact.
The other half of the study tells a different story — rebuilds that built rankings and grew traffic. The difference is visible before launch.
Atomicdust is a St. Louis brand and digital agency. SEO and content strategy are built into every site project we take on, not bolted on after.The other half of the study: portcos that grew through their transitions.
These aren't outliers. They're the other side of the bimodal pattern. Each of these portcos went through a meaningful site change. A rebrand, a platform migration, or a major content overhaul — and came out with stronger organic performance than they started with.
What separates these from the declining sites in the dataset: they treated the site transition as a strategic milestone tied to the company's story, not a delivery milestone tied to a launch date. Content that already ranked was carried forward — not swapped out for new copy. And investment continued after launch.

Four moves that separate the growth stories from the damage stories.
Start at close. The strategy phase is the first 6 months.
The work that distinguishes a growth-story rebuild from a damage-story rebuild happens before the first design comp. Audit the existing site, align the brand to the new ownership story, capture an SEO baseline, map the rebuild risks. The actual build launches in months 6–18. Rushing the build to a board meeting is what produces the damage we measured.
Know what's driving traffic before you change anything.
Every portco we audited that grew through a rebrand had visibility into which pages ranked, for which keywords, and why — before any changes were made. Every portco that declined had either lost that visibility or never had it. Pull the data at acquisition. Identify the top 20 pages that drive meaningful organic traffic. Protect them — or plan replacement content and redirects deliberately.
Treat the site as an asset, not a deliverable.
The clearest pattern separating growth from decline in our dataset: growth-story portcos kept investing after launch. Fresh content, regular updates, continued SEO work. The declining sites were shipped and walked away from. Among the 50 portcos we audited, one in every six had homepage content last updated 18+ months ago — including several with active acquisitions in the past year.
Measure after launch, not just at launch.
Organic data in the first 30–60 days post-launch is volatile while Google reprocesses the site. The honest read comes in months 4–8. Agencies whose engagement ends at launch don't live inside that window. That's why growth-story portcos had ongoing partners — not just project agencies.
Questions we hear from operating partners.
The rebuild isn't the risk. Rebuilding without a strategy is the risk.
The portcos that grow through transitions are the ones that treated the site as the strategic anchor of the hold period.
Let's talk about your portfolio companies websites.
Most PE engagements start with a quick call. We’ll ask about the portco, the current site, and your timeline. You’ll leave with a clear sense of what’s at risk and what’s worth doing before the agency starts work.
