Most teams try to optimise ROI using proxy metrics: clicks, CTR, form fills, and on-site behaviour. Useful, but incomplete. If phone calls are part of your customer journey (and for most B2B and high-consideration categories they are), the biggest ROI gains usually sit in what you cannot see.
Delacon helps you connect campaigns to real outcomes by linking customer interactions, call intent, and conversion data into one clear view. Start with Call Tracking and layer in CRM outcomes, reporting, and AI-driven insights to spot what is working, fix what is not, and back every decision with evidence.
If you’re new to the platform, start with Getting Started with Delacon, then come back here.
1. Make ROI measurable by tracking the full journey
ROI improves fastest when you stop optimising for “activity” and start optimising for “outcomes”. That means you need attribution that includes calls, not just web conversions.
Start by implementing Delacon’s Call Tracking and ensuring you can report on:
- which channel drove the call
- which campaign, keyword, ad and landing page influenced it
- whether the call was high-intent
- whether it became revenue (or at least a qualified lead)

ROI win: once calls are included, you can shift spend away from “high click, low value” traffic and into the channels that actually create opportunities.
2. Improve ROI by reducing wasted spend, not by “spending smarter” slogans
A practical way to increase ROI is to set up a weekly routine:
- Identify your highest-cost campaigns
- Review which ones produce high-intent calls (not just calls)
- Cut spend on poor quality traffic
- Reallocate budget to the campaigns that drive outcomes
- Repeat
Delacon makes this easier by giving you call-level source data you can use immediately, and by pushing outcomes into the tools you already use.
There are a number of real-world stories of how Delacon helped businesses like yours, including an example of ROI uplift, an effective reduction in cost per lead, and a strong example of how to reduce CPA.
ROI win: you stop funding campaigns that look good in dashboards but do not convert in the real world.
3. Close the loop with CRM outcomes (this is where ROI becomes board-ready)
Attribution gets much more powerful when you can tie calls to outcomes inside your CRM: qualified leads, opportunities, sales, policy starts, bookings, and revenue values.
This “closed loop” view lets you answer the questions leadership actually cares about:
- which channel creates the most revenue
- which keywords drive the best lead quality
- what the real CPA is after removing junk calls
- which campaigns deserve more budget
Use Delacon to match call data with CRM outcomes, then push those outcomes back into marketing platforms to improve optimisation.

ROI win: you optimise toward what converts, not what gets clicked.
4. Use Speech Analytics to turn “calls” into actionable conversion intelligence
Once calls are attributed, the next ROI uplift comes from understanding what happens inside them. That’s where Speech Analytics helps: intent, sentiment, objections, outcomes, and repeatable patterns.
Delacon’s Speech Analytics records inbound calls, generates transcriptions, and then uses AI to automatically categorise calls (like sales enquiries, service enquiries, complaints and cost concerns), score sentiment, and surface keywords/topics via search and word clouds.
It also supports dual-channel recording (separating caller vs agent), confidence scoring to help you prioritise review (for example, where a booking was discussed but not completed), and integrations/exports so call insights can be connected with your wider marketing, CRM, and BI reporting stack
Use it to:
- identify sales leads automatically
- spot pricing objections early
- surface website friction (people calling because they are stuck)
- flag negative sentiment before it becomes churn
- improve scripts and coaching using real calls
- track compliance-sensitive conversations
ROI win: you lift conversion rates, not just lead volume, by improving what happens after the phone rings.
5. Reduce missed opportunities with Call Management (ROI is not just marketing)
ROI isn’t only about ad spend. If calls are not being answered, every “good lead” is still wasted.
Delacon’s Call Management helps businesses route inbound calls efficiently and reduce missed calls, with toll-free, local and mobile numbers plus SIP/VoIP options. Key features include Interactive Voice Response (IVR), geo-routing (route callers to the nearest location automatically or via postcode/zip prompts), time-based routing, ring groups/round-robin, and automatic failover to alternative numbers if calls go unanswered or there’s an outage or capacity issue. It also includes missed-call email alerts (with optional cloud voicemail links) and an online portal where teams can update termination numbers and view reporting in real time.
Call Management helps protect ROI by ensuring calls are routed properly, handling spikes, and providing failover options.
ROI win: you keep more of the demand you are already paying for.
6. Make reporting simple enough that it actually gets used
If your reporting takes days, it won’t be used for optimisation. Faster reporting increases ROI because teams make more decisions, more often.
At minimum, set up:
- one performance view for marketing (calls by source, campaign, keyword, landing page)
- one quality view for sales (lead intent, call outcomes, high value conversations)
- one executive view (cost vs outcomes, ROI trends, top channels)
With Delacon’s new Portal, Genesis, combined with the power of Insights IQ, setting this up has never been easier.
ROI win: less time stitching reports, more time reallocating budget and improving performance.
7. Set up alerts and email templates (don’t miss leads)
Your ROI levers differ by industry. Use the relevant industry playbook to match your tracking, reporting and call strategy to your buyer journey:
- Agencies & Directories
- Finance & Insurance
- Franchise & Multi-location
- Healthcare & Education
- Professional Services & Other
- Real Estate & Construction
- Retail & Travel
- Utilities & Government
ROI win: you stop using generic benchmarks and instead optimise based on how your customers actually buy.
