Having selected your niche and keywords, you’re now ready to build the real foundation of your website.
This step takes you through everything from domain and hosting choices to the technical setup and essential tools.
When done right, it means your site is fast, crawlable, mobile-friendly, secure and ready for search engines and visitors.
Website Setup & Technical SEO Basics
“Technical SEO” sounds complex, but really it’s about making sure search engines can crawl, index, and trust your site, and users can use your site easily on any device.
In 2025, the emphasis is stronger than ever: user experience matters big time, and search engines (especially Google) expect sites to be technically sound.
A few critical macro-areas:
- Speed and performance (loading time, interactivity, layout stability)
- Secure hosting & HTTPS
- Mobile and responsive design (mobile-only indexing in effect)
- Site architecture (logical structure, clean URLs, no broken links)
- Crawlability and indexability (sitemaps, robots.txt, canonical tags)
Let’s break them down as they relate to the blog, affiliate, or business site types.
Domain & Hosting

Choosing the Right Domain
Your domain name is your identity online – choose smart. Two main kinds:
Brandable domain:
- Unique,
- Memorable,
- Gives you freedom.
Keyword-rich domain:
Contains the main search keyword for your niche, e.g., phlebotomycourse.uk if your niche is phlebotomy training.
What to consider:
- If you plan to expand beyond one niche, a brandable domain gives flexibility
- If you’re laser-focused on one niche and want immediate relevance, a keyword-rich domain can help
- Avoid being overly generic, spammy or limiting (what if you expand later?)
Best Hosting Options
Hosting affects uptime, speed, security – all of which impact SEO and user experience. Here are the options:
Shared Hosting:
Most affordable; resources are shared with other sites. Good for starter blogs/small sites.
VPS (Virtual Private Server):
More dedicated resources, better performance, suits growing sites.
Cloud Hosting:
Highly scalable, excellent performance and uptime ideal for larger, traffic-heavy or multi-niche sites.
Tip: Even if you start small, ensure your hosting provider has a strong reputation for speed, uptime, and support. Because poor hosting will hold back your SEO no matter how good your content is.
Website Type & Themes
Blog/News Websites
If you are setting up a blog or news-style site (e.g., frequent posts, updates, commentary), you’ll want:
- A theme that supports frequent publishing and categorisation
- Good navigation, tags/categories, author support
- A layout that scales as you add more posts
Affiliate/Authority Sites
For niche affiliate or authority sites (reviews, product-comparisons, guides) you’ll need:
- Clean design that builds trust (affiliate disclosure, user-friendly design)
- Ability to showcase products, review formats, comparison tables
- A theme with built-in schema support (so reviews, rich results work)
Business/Service Websites
If your site represents a business or service (local or global), you’ll need:
- Clear service pages, location pages (if local)
- Strong call-to-action, testimonials/pricing sections
- A theme optimised for conversions + local SEO if applicable
Choosing the Right Theme
Whatever type you choose, the theme must tick three boxes:
- Fast performance: lightweight code, minimal bloat
- SEO-friendly: good markup, schema support, clean HTML, mobile-friendly
- Mobile-first and responsive: in 2025, mobile performance is non-optional.
Tip: Before activating the theme, test its demo for speed (using PageSpeed Insights or Lighthouse), check mobile display, verify it supports schema and doesn’t load too many unnecessary elements/plugins.
Plugins & Tools
Since many websites use WordPress, here are the plugins and tools you’ll want to install early:
SEO Plugins
- Rank Math
- Yoast SEO
- All in One SEO
Speed Optimization
- WP Rocket
- LiteSpeed Cache
- WP Optimize
Security
- Sucuri
- iThemes Security
- Wordfence
These help with metadata, sitemap generation, schema markup, canonical tags, and more. Also optimise images (WebP/AVIF), lazy-load, defer non-critical JS/CSS – these are must-haves in 2025. Security and HTTPS aren’t optional anymore; they impact rankings and trust.
Technical Setup Checklist
Here’s a clear checklist of the key technical items you should set up before or immediately after launch:
SSL (HTTPS)
Get an SSL certificate and force site to HTTPS (redirect HTTP to HTTPS). Google treats security as a must.
Sitemap & robots.txt
Generate and submit your sitemap; ensure your robots.txt allows indexing of important pages.
Mobile-friendly design
Ensure your site looks and works well on mobile; Google uses mobile version first.
GSC & Analytics
Set up Google Search Console and Google Analytics 4 (GA4) to track indexing, traffic, errors, and user behaviour.
Tags and URL
Make sure your URLs are clean, unique, canonical tags are set so no duplicate content issues.
Core Web Vitals
Use tools like PageSpeed Insights, Lighthouse; aim for new 2025 thresholds (LCP < 2.5 s, CLS < 0.1, FID/INP low).
Schema markup
Add appropriate schema to help search engines understand your content and display rich results.
Fast Hosting and Caching
Your hosting, theme, and plugins must all be optimised for speed. Slow sites lose traffic and rankings.
Final Thoughts
Step 2 – laying your SEO foundations is absolutely critical. Without a technically solid site, even the best content and backlinks may struggle to rank well.
In 2025, search engines expect sites to be secure, mobile-optimized, fast, and structured for both users and crawlers.
Once you’ve completed these foundations, you’re ready to move on to On-Page SEO and Content Strategy, which will be covered in Step 3.
