Centennial Marketing in Oklahoma City: Full-Service Digital and Traditional Strategy for Mid-Market B2B Firms

Centennial Marketing is a full-service agency in Oklahoma City that handles SEO, paid media, content strategy, and creative production for mid-market business-to-business companies. The firm operates on retainer engagement, typically starting at $3,000 per month for ongoing optimization work, and serves clients across manufacturing, professional services, and software sectors in and outside Oklahoma.

What Centennial Marketing actually does

Centennial Marketing combines in-house digital strategy with outsourced creative execution. The agency's core offering is performance-based digital marketing: SEO audits and optimization, Google Ads management, and LinkedIn advertising for lead generation. A secondary service line handles content production, from blog strategy to case study writing. The firm does not offer traditional media buying (broadcast or print) and explicitly positions itself as digital-first, meaning clients seeking radio or TV spots should look elsewhere. Retainer work makes up roughly 70 percent of revenue; the remaining 30 percent comes from project-based engagements like website audits or one-time campaign builds.

Services and pricing tiers

Entry-level retainers begin at $3,000 monthly and cover basic SEO maintenance, monthly reporting, and one strategic planning call. At $5,000 monthly, clients add paid-media management (Google Ads or LinkedIn) and a second monthly strategy session. The $8,000+ tier includes all above services plus dedicated account management, custom content calendars, and monthly competitor analysis. Project work is quoted individually; a typical SEO audit runs $1,500 to $2,500, and a 12-article content calendar costs $3,000 to $4,500 depending on research depth. Confirm current pricing before engagement, as retainer minimums shift with team capacity.

How Centennial compares to other Oklahoma City marketing agencies

Centennial differs from Legacy Marketing Group (also based in Oklahoma City), which emphasizes brand strategy and creative design for consumer-facing companies and charges $4,000 starting retainers but requires longer commitments. Centennial's $3,000 floor is lower and suited to manufacturers or B2B service providers willing to start lean. Unlike agencies such as Elevate Creative (Oklahoma City), which bundles in social media management and video production, Centennial outsources video and treats social as secondary to SEO and search advertising. For a B2B industrial company needing LinkedIn lead gen and technical blog content, Centennial's focus is narrower but deeper. For a mid-sized consulting firm wanting a cohesive brand story across all channels, Legacy or Elevate may be stronger fits. Centennial does not position itself as a branding shop; it positions itself as a demand-generation engine.

Who this suits and who it does not

Centennial is built for manufacturing firms, software vendors, and B2B service providers (staffing, accounting, engineering) with annual marketing budgets of $36,000 to $150,000 and sales cycles of 60 days or longer. It suits companies already running some digital ads but unsure whether their spend is efficient. It does not suit early-stage startups without defined buyer personas, consumer brands prioritizing Instagram or TikTok reach, or organizations needing in-house design teams. It also does not suit firms demanding monthly creative refresh or narrative-heavy brand storytelling; Centennial delivers analytics dashboards and lead reports, not brand architecture workshops.

What the first engagement involves

An initial consultation (typically 30 minutes, no fee) covers your current marketing stack, revenue targets, and current cost per lead. If you move forward, a week-long audit phase ($0 to $500 add-on, depending on tier) includes a site crawl, competitor keyword analysis, and a 10-15 page findings deck. You then enter the retainer at the agreed monthly level. During month one, the team builds out account structure in Google Ads or LinkedIn Campaign Manager, sets up tracking, and finalizes KPIs. Reporting begins in month two. Most clients see meaningful data (lead volume, cost per acquisition trend) within 60 to 90 days.

Hours, location, and logistics

Centennial operates from a shared office space in Bricktown (specific street address available on their site). The firm keeps 8 a.m. to 5 p.m. hours, Monday through Friday. All primary communication happens via email, Slack, or monthly video calls; you do not need to visit in person. They accept new clients on a rolling basis but typically fill retainer slots 4 to 6 weeks in advance during peak hiring seasons (spring and fall).

Centennial Marketing fills a deliberate niche in Oklahoma City: for mid-market B2B firms tired of blanket creative pitches and wanting transparent, measurable digital work, it delivers. For those needing more than Google Ads and blog posts, or less structure than a full agency retainer, other options are stronger fits.
