## How does Synter balance prospecting and retargeting spend across platforms?

> **Summary:** Synter allocates budget between prospecting (new audience acquisition) and retargeting (re-engaging prior visitors and leads) based on funnel health metrics — monitoring pipeline volume, audience pool sizes, and conversion rates to maintain the balance that produces the lowest blended CPA.

Prospecting and retargeting serve fundamentally different functions in the acquisition funnel: prospecting fills the top with new potential customers, while retargeting converts those who have already shown intent. Synter's agent monitors this balance continuously across all connected platforms [[1]](https://syntermedia.ai/features/ai-agents). Prospecting campaigns run on broad audience targets — interest segments, lookalike audiences, and keyword-intent targeting on search — with success measured by downstream pipeline entry. Retargeting campaigns run on defined intent segments — website visitors, video viewers, lead form openers, abandoned cart users — with success measured by conversion rate and cost-per-conversion from audiences that have already shown purchase intent. The agent monitors audience pool health for retargeting: if the retargeting audience grows (prospecting is working) but conversion rates hold or improve, the current balance is healthy. If the retargeting audience shrinks while conversion rates rise, prospecting spend may be insufficient to maintain pipeline flow, and the agent recommends shifting budget toward acquisition [[2]](https://syntermedia.ai/meta-ads-ai-agent). Cross-platform coordination ensures retargeting coverage: a user who clicks a Google Search ad and visits the site is then addressable on Meta, LinkedIn, and TikTok for retargeting — the agent ensures consistent messaging across platforms for users at the same funnel stage.

## What budget split frameworks does Synter recommend for different business models?

> **Summary:** Synter applies different prospecting-to-retargeting budget frameworks based on business model, sales cycle length, and funnel stage. High-velocity B2C e-commerce skews toward retargeting efficiency; long-cycle B2B skews toward prospecting and pipeline nurturing.

Budget split recommendations from Synter's agent vary by business model and funnel characteristics [[1]](https://syntermedia.ai/features/ai-agents). For B2C e-commerce with short purchase cycles, retargeting is typically high-efficiency: users who visit product pages and abandon carts convert at significantly higher rates than cold audiences, justifying 40–60% of social spend in retargeting campaigns at early scale. As the retargeting audience saturates, the agent recommends increasing prospecting allocation to replenish the top of funnel. For B2B SaaS with longer sales cycles, prospecting and mid-funnel nurturing typically warrant 60–75% of budget: the qualified audience pool is smaller, the consideration period is longer, and brand presence during the evaluation window matters. Retargeting for B2B focuses on re-engaging decision-makers who have visited key pages (pricing, case studies, competitor comparison pages) and warming leads that entered the CRM but have not progressed. For lead generation businesses (professional services, financial products), the agent typically runs a 50/50 baseline and monitors lead quality metrics — not just lead volume — to determine which allocation produces the highest conversion rate from lead to qualified opportunity [[3]](https://syntermedia.ai/features/attribution). The agent adjusts these baselines continuously as conversion data accumulates, moving toward the allocation that produces the lowest cost-per-qualified-outcome.
