The right amount of JavaScript is less than you have
We write JavaScript for the interactions that need it, and we spend at least as much time removing the scripts that are slowing your site down without anyone noticing.
How we use JavaScript
Our default is progressive enhancement. The page works as HTML first, then JavaScript makes it nicer. A menu that opens, a filter that updates without a reload, a form that validates as you type. If the script fails to load on a bad connection, the visitor can still buy from you.
Interface behaviour
Menus, modals, filters, accordions, carts, and multi-step forms. Written to work with a keyboard and announced properly to a screen reader, because custom interactions are where accessibility usually breaks.
Integrations in the browser
Booking widgets, chat, payment elements, and third-party embeds, loaded so they do not block the page from rendering while they wake up.
Tracking that reflects reality
Real events on the actions that matter, wired through a tag manager container that somebody actually maintains, so your analytics answer questions instead of raising them.
Server-side JavaScript when it is already there
We maintain Node services clients already run. For new backend work we default to Ruby on Rails, and we will tell you when that preference should lose to your team's.
Where JavaScript helps, and where it hurts
Helps: interactions that would otherwise be page loads
Filtering a product list, adding to a cart, expanding a detail. Removing a round trip is a real improvement people feel.
Helps: forms that guide people
Inline validation, conditional fields, and clear errors reduce abandonment, especially on a phone and especially for people using assistive technology.
Hurts: content that only exists after a script runs
If your service descriptions are rendered by JavaScript, you are betting your search visibility on how well crawlers and AI answer engines execute your bundle. Server-rendered HTML removes the bet.
Hurts: custom controls built from plain elements
A dropdown made of divs has no keyboard behaviour and no name a screen reader can read. Either use the real element or accept that the accessibility work is now your job.
Hurts: scripts nobody owns
Every widget you install keeps loading long after the campaign that justified it ended. We audit that list, because it is usually the single biggest performance win available.
The heaviest code on your site is probably not yours
On most small business sites we audit, the code the developers wrote is a small fraction of what the browser downloads. The bulk is third-party: a chat widget, a heat-mapping tool, two advertising pixels, a review embed, and a popup builder, each pulling in its own framework.
Nobody decided to do this. Each one was added for a good reason on a different Tuesday, and none of them were removed. We inventory them, measure what each costs in load time, and give you a list with the trade-off written next to it. Some earn their weight. Most do not.
Questions we get about this
- Can you audit the third-party scripts slowing down our site?
-
Yes, and it is often the cheapest performance win available. On most small business sites the code the developers wrote is a small share of what the browser downloads. The rest is a chat widget, a heat-mapping tool, two ad pixels, a review embed, and a popup builder.
We inventory every script, measure what each costs in load time, and hand you a list with the trade-off written next to it. You decide what stays. Some of them genuinely earn their weight.
- Will Google Tag Manager slow down my site?
-
A well-configured container has a negligible effect on performance. A bloated one adds up. Keeping it lean is part of doing it right, and we check performance as part of the setup.
- Will it be accessible?
-
Yes. We build to WCAG standards on every project. If you have specific compliance requirements, tell us upfront and we'll scope accordingly.
- Will SEO work if my site is slow or hard to use?
-
Not as well. Technical health and usability are part of search ranking now, so a slow or confusing site limits your ceiling. Sometimes the highest-value search work is fixing those fundamentals first.
Site feels slow and nobody can say why?
That is usually a script problem rather than a hosting problem. In a free consultation we will look at what your pages are loading and tell you which two or three things are costing you the most.
