Senior Marketing Manager, Website Growth

Webflow is an agentic web marketing platform for modern marketing teams that helps organizations build, manage, and optimize high-performing web experiences. The Senior Marketing Manager, Website Growth will own web optimization, experimentation, AEO execution, website development, conversion architecture, measurement, and AI-enabled growth workflows to turn webflow.com into a qualified pipeline engine.

Responsibilities:

• Own web optimization and A/B testing in partnership with the demand-gen team. Run a structured, high-velocity experimentation program on webflow.com — hypothesis to live test to statistically valid result — using our experimentation and personalization stack (Webflow Optimize and equivalents). Set the test roadmap, defend statistical rigor, and turn win rate and conversion lift into reported KPIs, not anecdotes
• Own the web-side execution of AEO in partnership with the AEO lead. The AEO lead owns methodology, measurement, and category strategy; you own what makes webflow.com win citations and manage site performance improvements, accessibility, site architecture best practices
• You are the AEO lead's trusted site-side partner — the one who turns their strategy into live citation wins on webflow.com
• Run webflow.com as a "living" website, not a project that ships and stops. Own the continuous development of the site — page and component build, design QA, performance, and iteration velocity — so the site is always evolving in-platform. This is the customer-zero narrative made real: Webflow on Webflow, demonstrated through webflow.com, built and optimized on our own product every day
• Turn webflow.com into an account-level pipeline engine. Lead the on-brand experimentation, personalization stack, and conversion architecture that converts ICP-matched traffic into qualified pipeline. Partner closely with Demand Gen to ensure web experiences reflect and reinforce active sales-led pipeline initiatives (ABM target accounts, named-account journeys, and campaign-specific landing experiences)
• Build and ship,beyond building briefs. Design, build, and ship landing pages and site experiences end to end in-platform — you're hands-on in the product, closing the loop from hypothesis to live page yourself rather than handing specs to a queue. (Anthropic growth-engineer archetype: high agency, technical hands-on build.)
• Own the web measurement layer. Instrument event tracking, funnel analytics, and attribution for site-sourced pipeline so every experiment and every AEO/answer-engine visit is measurable end to end — and so web's contribution to pipeline is provable, not asserted. (Profound archetype: answer-engine visibility instrumented as a measurable funnel.)
• Support campaign orchestration across the web as a channel. You don't own or operate the orchestration engine — you represent webflow.com as a coordinated channel within it. Wire site behavior signals and on-site responses into the cross-channel play, and execute the web slice of an orchestrated account motion so a single account signal (AEO citation, site behavior, paid engagement) triggers a coordinated web response, not a siloed one. Partner with Marketing Ops, RevOps, and the AI-native team who own the orchestration layer
• Drive opportunities for Sales as the north star, instrumenting the signal-to-pipeline feedback loop that makes intent signals a stronger conversion predictor than firmographic ICP rating
• Partner cross-functionally as a peer to Demand Gen, Partner Marketing, PMM, and the broader Revenue org, protecting scope clarity while making Growth Platforms the substrate the entire Revenue Marketing org runs on
• Own and optimize a high-traffic B2B SaaS marketing website as a product, driving continuous improvements across user experience, performance, conversion, and experimentation rather than managing one-off website projects
• Define and lead a mature experimentation program, establishing testing strategy, experimentation infrastructure, and best practices while delivering measurable improvements in conversion and pipeline through statistically rigorous testing
• Bring deep expertise in technical SEO and Answer Engine Optimization (AEO), implementing structured data, crawlability, site architecture, and content optimizations that increase both organic search visibility and AI-powered answer engine discoverability
• Leverage marketing analytics to drive business outcomes, implementing instrumentation, funnel analytics, attribution, and measurement frameworks that demonstrate marketing's contribution to qualified pipeline and revenue
• Apply AI to production growth workflows, deploying AI agents and automation to improve content, routing, personalization, and optimization while maintaining appropriate human oversight
