Your main website and your campaign landing pages have different jobs. The website explains who you are to everyone. A landing page has one job, for one audience, from one traffic source: get the click to convert.
That difference is why so many teams run landing pages on a separate platform. It is also why the choice is not as obvious as it looks.
A benchmark to keep in mind
Unbounce analysed over 41,000 landing pages and 464 million visits and found a median conversion rate of 6.6% across industries (Unbounce). Treat that as a rough reference point, not a target. Industry, offer and traffic source move the number dramatically.
Option 1: A dedicated landing page platform
Instapage and Unbounce are the two names we are asked about most.
Why teams choose them
- Speed to launch. Marketers can build and publish without developers.
- Testing built in. A/B testing and variants are part of the workflow.
- Ad alignment. Features like dynamic text replacement help match page copy to ad keywords.
- Campaign focus. No navigation, no distractions, one goal.
How they differ, broadly
- Unbounce is popular with performance marketers and agencies for fast building and testing, and includes AI-assisted features for routing visitors to the best-performing variant.
- Instapage leans toward larger teams running paid media at scale, with strong collaboration and personalisation for different ad groups and audiences.
Both are capable. The better fit usually comes down to your team’s workflow, the volume of pages you run and how you manage paid media.
Trade-offs
- Another subscription and another place for brand drift.
- Pages usually are not designed to rank in organic search.
- Data needs to be connected carefully to your CRM.
Option 2: Your main CMS
Building landing pages in HubSpot, WordPress or Webflow keeps everything in one system.
Why it works
- Shared components keep pages on brand automatically.
- Pages can rank in search and contribute to your domain.
- Forms and tracking feed directly into your CRM, particularly on HubSpot.
Trade-offs
- Testing and ad-alignment features may be less advanced.
- Without good templates, marketers still depend on developers.
Option 3: A custom build
When it makes sense
- High-traffic programmes where every millisecond counts.
- Complex personalisation, calculators or product-led experiences.
- Large-scale ABM programmes with dozens of account-specific pages.
Speed is worth taking seriously. The Google-commissioned “Milliseconds make millions” study associated a 0.1-second improvement in mobile load time with an 8.4% increase in retail conversions and lower bounce on lead generation pages (web.dev).
Where AI changes the equation
The biggest shift is personalisation at scale. Instead of one landing page per campaign, AI-assisted workflows can generate a tailored page for each target account or segment, drafting headlines, examples and proof points for people to review and approve.
McKinsey’s research found personalisation most often drives a 10–15% revenue lift (McKinsey). What used to be too labour-intensive for more than a handful of accounts is now practical for fifty or more. We describe that process in detail in personalized landing pages at scale.
How to choose
| Priority | Best fit |
|---|---|
| Launch and test paid campaigns quickly | Instapage or Unbounce |
| Pages should rank, share components and feed the CRM | Your main CMS |
| Performance-critical or highly personalised programmes | Custom build |
| ABM with many account-specific pages | Template-driven build with AI-assisted personalisation |
The takeaway
The right home for your landing pages depends on how fast you need to move, how you measure success and how personal the experience needs to be. Many teams use more than one option, and that is fine, as long as the brand and the data stay consistent.
