Marquee Dental Partners was scaling rapidly but their digital marketing infrastructure was fragmented across vendors. Websites, ad accounts, listings, and tracking were disconnected with no single source of truth. New location launches took months. The previous agency optimized for vanity metrics while costs rose and patient volume stagnated. Simple updates took weeks. Leadership had no confidence in where budget was going or what was driving growth.
Solution
In 14 days, DeltaV launched 55 new websites across 75 locations with zero downtime and no loss of local SEO equity. We unified all digital assets under one platform, then rebuilt paid campaigns around appointment-level attribution instead of clicks. We implemented advanced scheduling and tracking to connect ad spend directly to booked patients. A standardized playbook was created so new location launches now go live with marketing from day one.
Result
Advertising spend cut by more than 50% while conversion volume doubled. 55 websites launched in 14 days across 75 locations with zero downtime. Full digital asset ownership restored for the first time. New location launches reduced from months to days with a repeatable, standardized process. Every location now has clear performance visibility through a single unified dashboard connecting marketing spend to patient acquisition.

This clients website had experienced five consecutive years of organic traffic decline at roughly 5% per year. The site carried significant technical SEO debt including crawl inefficiencies, index bloat, broken internal links, redirect chains, and duplicate content across programs and admissions pages. Prospective students could not easily find programs through search, and the path from discovery to application was unclear. Peer institutions were investing heavily in digital, widening the gap.
Solution
DeltaV executed an integrated SEO program across three phases. First, a full technical remediation resolved crawl issues, redirect chains, and index bloat. Then we optimized meta tags, headers, and on-page content across 300+ pages to align with real prospective student search behavior. Finally, we consolidated roughly 200 redundant pages into clearer, stronger resources and streamlined pathways to the Apply button so the journey from search to application was intuitive.
Result
Reversed a 5-year traffic decline, growing organic sessions 8% year over year (525,631 to 566,771), a 13 percentage point swing. Organic keyword coverage increased 32% as optimized content began ranking for intent-driven queries prospective students actually use. 300+ pages optimized and 200 redundant pages consolidated. Streamlined user journeys from search to application now support stronger inquiry and enrollment performance. The partnership continues into its sixth year.

Challenge
A major national health nonprofit suffered a catastrophic organic traffic collapse after a failed website migration. Rankings disappeared, redirects broke, and content that took years to build authority around was lost overnight. Multiple website properties had never been consolidated, creating fragmented authority and duplicate content. SEM campaigns were underperforming. Digital donation revenue was declining. Every dollar of lost traffic meant less funding for research and patient support pro
Solution
DeltaV rebuilt the SEO foundation from the ground up. We fixed migration damage including broken redirects, lost pages, and indexing errors, then consolidated multiple properties into a unified site architecture. We developed an annual content plan to compound authority year over year. The SEM program was restructured around three pillars: brand awareness, mission promotion, and fundraising. We connected organic and paid search intelligence so both channels improved continuously.
Result
Organic traffic grew from 17M to 105M annual visits with an estimated traffic value of $330M. SEO drives 84% of all website visits and 40% of all digital donations. SEM generates 25% of donation revenue from just 1% of traffic at 220% ROAS. Cost per acquisition dropped from $165 to under $22. Combined SEO and SEM account for over 65% of all digital donations, making integrated search the organization's largest fundraising channel.
We build SEO, AIO/GEO, CRO, and web strategies that help brands get found in Google, AI answers, and beyond, then turn visibility into qualified leads, stronger conversions, cleaner UX, sharper content, faster execution, & measurable revenue growth.
