Slow responses from a web agency usually come down to capacity, not your website. Here's what causes the delay, what it costs a business-critical site, and how to tell if you're already exposed.

I started working with ExpressionEngine in 2007. At the time it was one of the most capable platforms available for complex content requirements, and the projects I was being handed reflected that: membership sites, booking systems, trade portals, internal tools built on top of a CMS.

ExpressionEngine and Craft CMS are not generic frameworks. A developer without platform experience can fix some things and quietly create others. Here is what platform specialism actually means when your site handles real business operations.

When a website handles live transactions, staff workflows, or customer accounts, the people responsible for it ask harder questions before bringing in external support. This is what procurement teams and IT managers typically check, and what it means in practice when you are looking for specialist ExpressionEngine or Craft CMS support.

Many businesses with ExpressionEngine sites manage leads manually because the site does not connect to their CRM. Here is what that gap costs and what integration looks like.

ExpressionEngine sites can develop technical issues that significantly reduce their visibility in Google search without any obvious signs. Here is what to look for.

ExpressionEngine can be connected to Stripe to handle payments, subscriptions, and deposits. Here is what that integration looks like and what it is suited to.

Most ExpressionEngine sites have no structured data. Here is what structured data does, what your site is missing, and what implementing it involves.

Running an old version of ExpressionEngine has consequences beyond security. Here is how an outdated installation affects the factors Google uses to rank your site.

Moving an ExpressionEngine site to a new server can cause quiet, persistent ranking drops. Here is what typically causes them and what should be done differently.

If your ExpressionEngine website includes an online store, there is a good chance it runs on CartThrob. CartThrob is the eCommerce plugin that powers purchasing, order management, and payment processing on ExpressionEngine sites. Version 9.0.0 has just been released, and while the announcement is aimed at developers, the implications are squarely about how your store operates.

A technically sound ExpressionEngine site can still underperform as a lead generation tool. Here is why, and what usually needs to change.

API integrations on ExpressionEngine allow the site to connect with external business systems. Here is what that means, what it involves, and what questions to ask.

Most businesses use multiple systems to run their operations: a CRM, an accounting package, a booking or scheduling tool, a stock management system. Their website, whether built on ExpressionEngine or Craft CMS, often sits apart from all of these, requiring manual data entry in both directions. That gap has a cost.

A significant part of the work we do at Expression 37 involves inheriting ExpressionEngine sites that were built by developers or agencies who are no longer involved. The circumstances vary, but the practical challenge is always similar: a site you didn’t build, with code you didn’t write, and decisions that were never documented.

If your ExpressionEngine or Craft CMS site connects to any external service, whether that’s Stripe for payments, HubSpot or Salesforce for CRM, or Mailchimp for email, you have a dependency that you probably don’t think about until it fails.

ExpressionEngine is a specialist platform. The community of genuinely experienced EE developers is small, particularly in the UK, and the difference between someone who has worked with EE seriously and someone who has touched it once or twice is significant.

This is a distinction that matters more than most business owners realise. The site is working. Pages load, content can be updated, forms submit. From the outside, everything looks fine. But working and maintained are two very different things, and the gap between them has a cost that compounds over time.

It is more common than most people realise. A business has been running an ExpressionEngine site for years, the relationship with the agency that built it gradually fades, and eventually there is no-one actively looking after the site. Understanding why this happens helps you know what to do about it.

Most business owners have no idea what state their ExpressionEngine site is in. They know it’s working, they can add content, and the contact form still sends emails. Beyond that, it’s a black box. Problems can accumulate quietly over a long period before they become visible.

Delaying an ExpressionEngine upgrade is easy to justify. The site still works, the budget is committed elsewhere, and nothing has broken yet. But delays in this area follow a predictable pattern, and the costs accumulate in ways that are not immediately visible.

PHP 8 is now the standard version running on most web hosting infrastructure. Many ExpressionEngine sites were built when PHP 7 was current and have never been reviewed for PHP 8 compatibility. If nobody has mentioned this to you, there is a reason for that, and it is worth understanding.

The question I get asked most often by business owners is some version of: what will this cost? It’s a fair question, and the honest answer is that it depends on things that are specific to your site. But there’s enough of a pattern to give you a useful framework.

If your website is running on ExpressionEngine 4 or 5, it may look fine on the surface. But underneath, you are carrying costs that most business owners do not see until something goes wrong. This is not about upgrading for the sake of it. It is about understanding what your current situation actually means.

Most businesses with an ExpressionEngine site didn’t choose ExpressionEngine themselves. A web agency built the site, recommended the CMS, and handled everything from launch onward. That arrangement works well until it doesn’t, and there are several ways it can stop working.

ExpressionEngine has changed hands several times over the years. The current owner, Packet Tide, acquired the platform and has been responsible for its ongoing development. If your business runs on ExpressionEngine, understanding who owns the platform and what their priorities are is worth knowing.

There’s no single answer to when you should upgrade your ExpressionEngine installation, but there are several clear signals that tell you it’s overdue. Most business owners don’t think about this until something goes wrong. By then, the upgrade is usually more involved than it would have been if it had been done earlier.

Many businesses commission an ExpressionEngine audit without being clear on what it should cover. Here is what a thorough audit examines and what it usually reveals.
