Website development built for speed, search and easy updates
MarquixAd is a website development company that builds marketing websites the way marketers need them: fast on every device, structured for search engines, connected to your CRM and analytics, and simple for your team to update without calling a developer.
What makes a marketing website well built
Two websites can look identical in a screenshot and perform completely differently. One loads in under two seconds on a mid-range phone, is understood by Google immediately, and lets the marketing team launch a new landing page in an afternoon. The other takes six seconds to become usable, hides content behind scripts search engines struggle with, and needs a developer for every text change.
The difference is in how it's built. Clean, semantic HTML; images served in modern formats at the right size; only the JavaScript a page genuinely needs; a content management system organised around reusable components; and tracking, forms and integrations set up correctly from the start.
These choices affect revenue directly. Faster pages keep more visitors. Search-friendly structure earns more organic traffic. A flexible CMS means campaigns launch sooner. Reliable integrations mean no lead is lost between your website and your sales team.
Our development principles
- Performance first: every page has a speed budget, checked against Core Web Vitals before launch.
- SEO built in: clean URLs, correct headings, canonical tags, XML sitemaps, schema and redirect handling.
- Editable by marketers: page builders or component libraries your team can use safely.
- Secure and maintainable: updated software, sensible permissions, backups and documentation.
- Accessible: keyboard navigation, labelled forms and screen-reader-friendly markup.
Who we build for
- Businesses replacing a slow, outdated or hard-to-edit website.
- Companies migrating platforms, for example from an old custom CMS to WordPress or a headless setup.
- E-commerce brands launching or rebuilding on Shopify or WooCommerce.
- Marketing teams that need landing pages launched quickly for campaigns.
- Agencies and designers that need a reliable development partner for approved designs.
Need design as well? Our website design team works alongside development from day one.
Development problems we fix
We're often brought in after a build has gone wrong, or when a site has slowly become a liability.
Slow loading
Heavy themes, unoptimised images and third-party scripts drag down speed and search performance. We rebuild or optimise to hit Core Web Vitals targets.
Plugin overload
Dozens of plugins cause conflicts, security risks and slowdowns. We consolidate to what's genuinely needed.
Broken forms and tracking
Enquiries go missing or aren't recorded in analytics. We fix submissions, CRM delivery and conversion tracking.
Developer dependency
Simple edits require a developer. We restructure templates so your team can update content confidently.
Security issues
Outdated software, weak access controls and no backups. We harden, update and put maintenance in place.
Risky migrations
Platform changes that lose rankings or content. We plan URL mapping, redirects and content transfer carefully.
Choosing the right platform
We don't push one platform. We recommend the one that fits your content, team, budget and growth plans.
| Platform | Best for | Strengths | Trade-offs |
|---|---|---|---|
| WordPress | Content-rich marketing sites, blogs, service businesses | Flexible, familiar editor, huge ecosystem, strong SEO tooling | Needs disciplined plugin use and regular maintenance |
| Shopify | Most e-commerce stores | Reliable hosting, secure checkout, strong app ecosystem | Transaction fees on some plans; less flexible URL structure |
| WooCommerce | Stores needing deep customisation or combined content and commerce | Full control, integrates with WordPress content | More hosting and maintenance responsibility |
| Headless CMS + modern framework | Larger sites, multiple markets, performance-critical builds | Very fast, secure, highly flexible, content reusable across channels | Higher build cost; needs developer support for new templates |
| Webflow | Design-led marketing sites managed by small teams | Visual editing, good performance, hosted | Less suited to complex functionality or very large sites |
Business benefits of a properly built website
Development quality is invisible when it's done well. It shows up instead in your numbers.
- Higher conversion rates because fast, stable pages keep visitors engaged.
- Better organic visibility from technically sound, crawlable pages.
- Faster campaigns when marketers can build landing pages from ready components.
- Lower running costs with fewer emergency fixes and less developer time on routine edits.
- Reliable data from forms, tracking and CRM integrations that work every time.
Our pre-launch checklist
Most launch problems are predictable. Before any site goes live, it passes every check on this list, and you receive the results in a launch report.
After launch, we monitor Search Console, analytics and uptime closely for the first few weeks, because some issues only appear once real visitors and search engine crawlers arrive.
- Speed: Core Web Vitals tested on mobile for every template, with images, fonts and scripts optimised.
- Search: titles, descriptions, headings, canonical tags, XML sitemap, robots.txt and schema validated; no staging pages left indexable.
- Redirects: every old URL with traffic or links mapped and tested with a 301 redirect.
- Forms: every form submitted end to end, confirmed in your inbox and CRM, with spam protection active.
- Tracking: GA4, Tag Manager, conversion events and consent behaviour verified in real time.
- Accessibility: keyboard navigation, focus states, contrast, alt text and form labels checked.
- Devices and browsers: tested on current versions of Chrome, Safari, Firefox and Edge, plus real iOS and Android phones.
- Security: HTTPS everywhere, admin accounts reviewed, backups confirmed and software up to date.
- Content: spelling, broken links, placeholder text and image rights checked on every page.

Website development: frequently asked questions
Technical question? Ask our developers.
How much does website development cost?
Cost depends on the number of templates, platform, integrations, content migration and functionality such as e-commerce or multilingual support. We give a fixed quote once requirements are documented.
How long does a website build take?
A typical marketing website takes four to eight weeks of development once designs are approved. Larger sites, complex integrations or migrations take longer. Your project plan sets out every milestone.
Which platform do you recommend?
It depends on your content, team and goals. The platform table above summarises when we'd choose WordPress, Shopify, WooCommerce, Webflow or a headless setup.
Can you build from designs we already have?
Yes. We develop from Figma or other design files, and flag anything that could affect speed, accessibility or editability before we start.
Will our site be fast?
We set performance budgets and test against Core Web Vitals on mobile before launch. Third-party scripts you add later can affect speed, so we advise on those too.
Will we keep our SEO rankings when we migrate?
Careful migrations protect rankings. We map every important URL, set 301 redirects, preserve metadata and content, and monitor Search Console closely after launch.
Can our team update the website?
Yes. We build reusable components, restrict risky settings, and train your team with documentation tailored to your site.
Do you integrate with our CRM and other tools?
We integrate with common CRMs, booking systems, payment gateways, email platforms and WhatsApp, and can connect custom systems via APIs or webhooks.
Where will the site be hosted?
We recommend hosting suited to your platform and traffic, with CDN, backups and SSL. The hosting account is set up in your name.
How do you handle security?
HTTPS, security headers, least-privilege access, spam protection on forms, regular updates and backups. Maintenance plans include monitoring and patching.
Do you offer maintenance after launch?
Yes. Plans cover updates, backups, uptime monitoring and a monthly allowance of development time for improvements.
Who owns the code?
You do, once the project is paid for. You receive the code repository, admin access and all credentials.
