  • Technical performance directly impacts conversions. Schema markup, page speed, and mobile optimization affect bounce rates, search visibility, and whether your marketing dollars convert or get wasted.

If you’ve ever been involved in a website redesign for your bank or credit union, you know what a big initiative it is for both your internal stakeholders and your customers or members. You also likely know that most institutions undertake a website redesign project every 3-5 years for any variety of reasons, among them differing organizational priorities and changing technology.

Website redesigns can be transformational projects. However, launching a pretty site that isn’t a high performing conversion engine is a waste of your time and your resources. In fact, today’s websites are a critical investment in your bank or credit union’s future — serving as an always-open branch, supporting existing visitors and communicating your unique brand in one of your most visible channels. So how can you measure the ROI of your next public website redesign?

Start By Defining SMART Conversions

Many tactics marketers pursue aren’t always quantitively measurable but guess what – a website isn’t one of them. If planned strategically, a new website can increase conversions for traffic that is already going to the site – including submitted site forms and third-party applications. For this reason, you’ll want to clearly identify a SMART conversion increase goal for your new site as the first step.

  • What you need to do: Every page of your new site needs to heavily focus on at least one call to action (e.g., Apply Now). Your new site’s user experience is critical to this goal being achieved. Importantly, this goal should be supported by a defined marketing plan to get additional, qualified visitors to the site in the first place. In addition, improving the user experience on every page to deliver content in digestible chunks, and in a relatable tone, can help visitors feel appreciated and nurtured along the sales cycle. Remember that financial services decisions are complex, so patience and time are key.
  • How to measure: If you want to know how much something increases, you will need to measure it in the first place. Before you begin a redesign, add custom analytics tracking to your current site — including cross domain tracking to any online account opening and loan vendors. This will establish a baseline to compare data to in the months after launch. Because this is a highly specialized task, you likely will need to enlist the help of a digital agency to support this. Make sure that you set up reports that have the most meaning to your organization. This data should be always available at your fingertips to help inform your every move.
  • Real life data: Curious how fellow banks and credit unions have implemented this recommendation?
    • A credit union in CA saw a 300% increase in loan application clicks which were tracked the weeks before and after their new site launched. They did heavy marketing of the new site when it launched, and also manually tracked closed loans to be able to directly attribute the business to marketing efforts.
    • A bank in CT had renamed and rebranded, launching a new site as the pinnacle of this. comparing data before and after launch, they saw a 20% increase in average session duration — which is a direct result of a richer content and resources to keep visitors engaged.

Have A Plan To Deliver Higher Quality Website Traffic

Just because you have a wonderful website does not necessarily translate to more people visiting it. This is where your job as a marketer becomes extra important.

  • What you need to do: Review your marketing plan critically — with the lens of what can drive quality traffic to your site — not just eyeballs. You will need to dissect every part of your current marketing plan to see what tactics are driving traffic to your website (which I hope is most of your tactics). Then you’ll want to closely evaluate the quality of that traffic. Are some tactics like paid ads generating traffic but not necessarily conversions? Are visitors getting to your site but not converting frequently?
  • How to measure: You will need to have custom analytics tracking on your site to do a deep dive. You’ll want tracking on every button/link/interaction and have cross-domain tracking to any site where a conversion could take place such as online account opening or loan forms. Tracking that someone clicked a button is one thing but tracking if they abandoned mid-form or submitted the form and became a customer/member are even more important. This data will help you truly determine what’s working and not working. It can also inform if you need to have a remarketing campaign in place.

Invest In Marketing Tactics That Best Result In ROI

There are proven digital tactics that data shows generate measurable ROI. While successful financial services marketing is attributed to a mix of tactics working in harmony, if you do have a wonderful new site, you want to ensure you’re putting your best foot forward with strategies that deliver real results.

  • What you need to do: SEO/GEO, paid search and remarketing are great, basic tactics that any bank or credit union should be investing in. The ability to drive traffic to your website on targeted search terms is especially important in the highly competitive financial services industry. Smaller or regional institutions have a distinct advantage over large, national institutions in these areas because they can target audiences within a specific geographic radius and cater to those who value convenience, personal service, and local trust. That said, if your institution offers competitive rates, this is exactly where you should highlight them. Importantly, you should leverage dedicated, conversion-focused landing pages for any paid campaigns to seal the deal. Email marketing and personalization would be additional tactics to explore to get more bang for your marketing bucks.
  • How to measure: By default, Google Analytics will identify the source of your traffic. But, when it comes to paid campaigns, you will need to connect Google Ads and other paid search campaigns to your analytics account. And as noted above, custom cross domain tracking to any third-party sites will allow you to monitor conversions.
  • Real life data: What have other institutions seen when doing this?
    • A Louisiana-based credit union implemented a mix of proven inbound marketing tactics when launching their new site, resulting in a 65% increase in clicks to apply for a mortgage. Since conversions were a pain point pre-launch, this was a great way to prove to management that the site was a powerful sales tool.
    • An institution in Virginia redesigned their site with an improved UX, a landing page for campaigns and a blog. Marketing campaigns and a conversion focused site resulted in 69% increase in “open an account” button clicks comparing the month before and after launch.

Personalization Can Yield More Conversions — If Strategized Well

Everyone is talking about personalization and for good reason. This tactic allows you to enhance the relevance of your content by tailoring promotions and content to specific target audiences, and relevancy drives engagement and conversions. The good news is that implementing personalization on your site can be done fairly painlessly and in phases that align with your goals and budget.

  • What you need to do: It’s important to start by defining a few key audiences and their goals so you can create personas. Personalization isn’t complicated — but having too many personas at once can get overwhelming so prioritize audiences that closely align with your marketing initiatives. Perhaps you are using a targeted mailing to drive people to the site via a QR code to give them a unique offer. Or maybe you are providing messaging to an audience in a defined geographic area about a new branch opening. A well-thought-out strategy will deliver the best results.
  • How to measure: Personalization is extremely trackable — whether it’s part of a CMS or a third-party offering. Site traffic will have a unique identifier which you can then use to set up custom reporting. You’ll want to ensure your agency provides a dashboard showing how personalized and non-personalized content compares. You will also want to continually evaluate and tweak your strategy. It may not always work, and that’s ok. But once it does, conversion rates are sure to skyrocket. Why? Because it simply makes sense: you’re delivering the right messaging to the right audience(s), at the right time.
  • Real life data: Does it really work? Yup — it sure does when it’s strategized thoughtfully and measured accurately.
    • A credit union in Wisconsin strategically revamped their website and created personalized content tied to key personas. One goal was to get more visitors to use online banking, and the personalized content outperformed the non-personalized content by more than double when comparing the months before and after launch.

A Redesign Can Help Support Customers And Members Too

A better site can also be a terrific resource for current customers or members. It’s widely known that retaining current customers or members is much easier than acquiring new ones, so having a data point catering to your current audience is important in measuring ROI from your redesign.

  • What you need to do: Identify some of the pain points your current site has regarding existing customer or member communication. Perhaps there is an opportunity to help your Service team by adding FAQs. Or maybe you don’t have a promotion in your Login area which could help with cross-sell messaging in a location that existing customers or members are going to 99% of the time anyway.
  • How to measure: Similar to the other tactics, you’ll want to set up custom conversion tracking on any tactic like an online banking login promo. An experienced analytics specialist will be able to reasonably identify “current customers” based on clicks on the online banking login button for example. Reporting can then be setup to track conversions.

Why The ‘Technical Stuff’ Matters To Support Conversions

Talking about schema, page speed and load time isn’t exactly exciting — but it sure is important. A website built with a solid technical foundation and optimized hosting environment will experience lower bounce rates, which means potentially more conversions. The last thing a marketer wants is to spend time and money driving traffic to a site that is then frustrating to a user — or even worse — seen less because search and AI engines are indexing it poorly as a result.

  • What you need to do: When investing in a site redesign, make sure that your digital agency not just checks the technical boxes, but understands exactly why this is a dealbreaker for your institution. Make sure that design, development and hosting decisions don’t comprise your site’s load time. Ask your agency what services you can enlist that will help make the site appeal to search and AI engines. For example, investing in schema code and optimizing site content can bring in more high-quality traffic, and position your site over others who don’t offer this AI-friendly structured data.
  • How to measure: Google Analytics is packed with data to help you understand how a redesign made a difference. Look at bounce/engagement rate and load time as a starting point. Then look at the Path Exploration report to see how users are navigating your site more efficiently post-redesign. You will also want to peek at mobile device engagement, Core Web Vitals, Google PageSpeed Insights and even see if there are unnecessary third-party scripts weighing your site down.

Websites for banks and credit unions have gotten more sophisticated, so investing in just another “pretty site” isn’t going to pass your budget approval processes. Instead, build your case for a site that is a conversion engine — and yes, it can be pretty while it’s working as hard as you do.
