SEO coding refers to the practise of optimising a website’s HTML, CSS, and JavaScript code to improve crawlability, indexation, and ranking performance. While keyword research and link building used to be enough, today’s competitive landscape requires expertise in programming efficient, semantically rich pages.

According to Moz, over 75% of SEOs say optimising for core web vitals is now one of their top priorities.

Optimizing for Core Web Vitals: The Need for Speed

Optimizing for core web vitals - seo coding

Core web vitals. Sounds technical, right? Well, optimising these metrics is essential for any website aiming to rank well in 2023 and beyond.

In plain English, core web vitals measure how quickly your site loads and displays content to users. We’re talking super-fast speeds that keep visitors engaged. No one wants to stare at a spinning wheel while a site takes forever to load!

Google has made it crystal clear that page speed and user experience are frontrunners for ranking success. So, let’s break down exactly what core web vitals are all about and how you can optimise like a boss.

Largest Contentful Paint (LCP)

These vital tracks how soon the main content loads. We’re talking hero images, big blocks of text – the good stuff above the fold. LCP aims for under 2.5 seconds. A sluggish LCP over 4 seconds will definitely hurt your rankings.

Follow these tips to shorten LCP time:

  • Compress those images! Shrink file sizes through lossless compression.
  • Minify CSS and JavaScript files. Streamline code to eliminate extra spaces and characters.
  • Use browser caching to store assets for faster page loads.
  • Enable text compression and content delivery networks (CDNs).

First Input Delay (FID)

This measures how quickly a page responds when users click or tap on links and buttons. Under one hundred milliseconds is the goal. Anything over three hundred ms feels downright sluggish.

To improve FID:

  • Minimize render-blocking JavaScript by deferring it.
  • Reduce the use of heavy libraries like Bootstrap or jQuery.
  • Optimize your images and videos by serving smaller file sizes.

Cumulative Layout Shift (CLS)

Ever see page elements like images or buttons pop around as a page loads? That’s layout shift, and it creates a jarring user experience. Keep CLS under 0.1 seconds.

Win the battle against CLS by:

  • Adding dimensions to images/videos so the browser can reserve space.
  • Avoiding “in-line” CSS as it can change layout after load.
  • Using CSS Grid and Flexbox for a stable layout.

There you have it! With this cheat sheet, you’re primed to achieve lightning-fast core web vitals and keep your visitors happy. Need a hand getting these technical optimizations implemented? Our expert SEO coding team has you covered there too. Let’s talk!

Implementing SEO Coding you Will Pump Up Your Pages with Structured Data

Implementing seo coding you will pump up your pages with structured data

Ever wonder how some sites get those snazzy little side panels called “rich snippets” in the search results? The answer is structured data, baby!

Adding structured data marks up your pages in a way that search engines absolutely love. It’s like giving Google extra hints by attaching schema markup to identify people, organizations, events, products, and reviews.

Implementing schema, the right way can pump up your rankings and click-through rates.

Here’s how to become a structured data master:

Choose the Right Schema

With so many schema types to choose from, it can get confusing. Start by identifying the most useful schema for each page. Article schema for blog posts, local business for contact pages, product schema for ecommerce items, and so on.

Add Schema Code

Next, neatly add the JSON-LD or microdata markup to define each element. For local businesses, be sure to include the business name, address, phone number, price range, and opening hours.

Test Your Implementation

Use Google’s Structured Data Testing Tool to validate your work. Make sure those rich results are ready to show up in the SERPs!

Fix Errors

This tool also catches errors in your schema. Common goofs include incorrect data types or missing required fields. Fix those bugs to avoid any Structured Data Penalties.

Ongoing Optimization

Get in the habit of adding schema to new pages and updating existing markup. Squeeze the maximum benefits out of structured data.

Bringing Order to Your Pages

Structured data not only improves search appearance, but also helps Google understand your content. By tagging page elements, you make your site more crawlable. The result? More traffic driven to the right pages.

Our schema wizards can implement perfectly optimized structured data across your site. Get ready to impress on the SERPs!

Designing for All Devices: Mobile-Friendly and Fabulous

Designing for all devices: mobile-friendly and fabulous

Let’s get real for a sec – most websites don’t look so hot on mobile devices. Tiny tap targets, wonky text formatting, and clunky navigation have plagued mobile users for too long!

With over 60% of search traffic coming from smartphones, mobile optimization is mission critical. If your site isn’t mobile-friendly, Google will pulverize your rankings faster than you can say “hamburger menu”.

Creating a seamless experience across devices isn’t so scary though. Just follow these tips:

Responsive FTW

A responsive design uses CSS media queries to adapt layouts based on screen size. As you resize the browser, elements should rearrange smoothly. No more pinching and scrolling to read text!

Watch Your Widths

Keep line lengths in the 50-75 character sweet spot. Any narrower and users have to work to read. Wider means awkward text wrapping.

Tap Those Targets

Fingers need ample space to tap links and buttons. Crank up element sizes so that tap targets are at least 48 CSS pixels.

Prioritize Content

Lead with the most important info and navigation links at the top. Nobody wants to endlessly scroll to find basics like contact info.

Test Like Crazy

Check the responsive design on multiple devices. Debug any layout quirks or small-screen mishaps.

Mobile Magic

Optimizing for mobile doesn’t have to give you a headache. With these fundamentals, you’ll give users an excellent experience on any device. Our team of UX all-stars can also help craft a slick mobile-friendly website. Let’s talk!

Tidy Up Your Website Blueprint

Your site’s architecture is more than just a sitemap – it’s the behind-the-scenes blueprint that makes or breaks user experience.

Like any good home, a website needs a solid foundation and layout to function. When the underlying structure is messy, pages become frustrating to navigate.

Let’s explore some renovation tips to create a seamless site architecture:

The Floor Plan

A clear URL structure should guide visitors to content in an intuitive flow. Organize pages by category, like:

example.com/services/web-development example.com/about-us/team

Interior Decorating

Navigation menus are the doors guiding users between pages. Keep main menus consistent across pages in placement and style.

Don’t Get Lost

Breadcrumb trails provide navigation cues so visitors can retrace their steps. They look like: Home / Services / Web Development

Renovate Rooms

Replace generic URLs like “page2.html” with descriptive, keyword-rich URLs.


Curb Appeal

Is your XML sitemap up to date? This file helps search engines index new pages.

Prevent Duplication

Redirect or update duplicate content to avoid search indexing issues.

With the right site architecture, you won’t get lost in a maze of disjointed, irrelevant pages. Let our experts provide a blueprint tuned for higher-converting site exploration!

Clean Coding for Search Engines

Let’s wrap up our SEO coding tour with some best practices for writing efficient, optimized code. Sure, fancy frameworks like React or Vue can build slick sites. But they can also bloat your code with unnecessary stuff that drags down performance.

Follow these tips for clean, lean code:

Cut the Calories

Get rid of unused libraries, redundant plugins, and overweight code frameworks. Use a minimalist approach instead.

Easy to Digest

Well-formatted code with descriptive comments helps future developers modify it without headaches.

Go Green

Minify JavaScript, CSS, HTML, and images to reduce file size. Turn on compression for faster transfer speeds too.

Validator Stamp of Approval

Run code through validation tools like W3C’s for optimal HTML, CSS, etc. Fix errors and warnings!

Function Over Form

Pick fast-loading, lightweight fonts and images tailored to your needs. Don’t overload on resource-hogging elements.

Marie Kondo Your Code

If code isn’t used, delete it! Remove outdated or redundant scripts and assets for a clean foundation.
