In 2018, SEO was undergoing major changes. Google began rolling out mobile-first indexing, introduced page speed as a ranking factor for mobile searches, and encouraged websites to adopt HTTPS by marking non-secure sites in Chrome. The Medic core update also emphasized expertise and trustworthiness. For website owners, adding SEO into a website in 2018 meant adapting to a mobile, secure, and quality-focused web. Many of those practices remain essential today. This article revisits how to add SEO into a website based on 2018 best practices and explains how they still apply.

Key SEO Changes in 2018
- Mobile-first indexing: Google began primarily using the mobile version of websites for indexing and ranking.
- Speed update: Page speed became a ranking factor for mobile searches.
- HTTPS push: Chrome started labeling HTTP sites as "Not Secure."
- Medic update: Content quality, expertise, and trust gained emphasis, especially for health and finance websites.
- Growth of voice search: Conversational queries and featured snippets increased in importance.
Step 1: Make Your Website Mobile-Friendly
With mobile-first indexing, a responsive design became essential. Websites needed layouts that adapted to different screen sizes, readable text without zooming, and tap-friendly buttons. Content on mobile needed to match desktop content so that nothing important was missed during indexing. Google's Mobile-Friendly Test helped site owners check their pages.
Step 2: Secure Your Site With HTTPS
Switching from HTTP to HTTPS protected user data and removed "Not Secure" warnings. Website owners installed SSL certificates, redirected all HTTP URLs to HTTPS with 301 redirects, updated internal links, and verified the HTTPS version in Google Search Console.
Step 3: Improve Page Speed
Fast-loading pages became a priority. Common optimizations included compressing images, enabling browser caching, minifying CSS and JavaScript, reducing redirects, and using content delivery networks. Tools like PageSpeed Insights and Lighthouse helped identify issues. Some publishers also adopted Accelerated Mobile Pages (AMP) to improve mobile speed.
Step 4: Conduct Keyword Research
Keyword research remained the foundation of SEO. Site owners identified keywords relevant to their products and services, analyzed search volume and competition, and increasingly targeted long-tail and question-based keywords to capture voice searches and featured snippets.
Step 5: Optimize On-Page Elements
- Title tags: Unique titles including primary keywords.
- Meta descriptions: Compelling summaries that encouraged clicks.
- Headings: Structured H1, H2, and H3 tags for clarity.
- URLs: Short, descriptive, keyword-relevant slugs.
- Images: Descriptive file names and alt text.
- Internal links: Links connecting related content.
Step 6: Create High-Quality Content
Following the Medic update, content quality became more important than ever. Websites needed to demonstrate expertise, authoritativeness, and trustworthiness. This meant adding author bios, citing credible sources, publishing in-depth content, and keeping information accurate and up to date.
Step 7: Add Structured Data
Schema markup helped search engines understand content and qualify for rich results such as reviews, recipes, events, and FAQs. Implementing JSON-LD structured data became a standard recommendation.
Step 8: Optimize for Featured Snippets and Voice Search
Featured snippets appeared at the top of many search results, and voice assistants often read them aloud. To target snippets, websites answered common questions concisely, used lists and tables, and structured content with clear headings.
Step 9: Submit Sitemaps and Monitor Search Console
In 2018, Google launched the new Search Console interface with enhanced reporting. Website owners submitted XML sitemaps, monitored indexing coverage, checked mobile usability, and reviewed performance data for up to 16 months.
Step 10: Build Quality Backlinks
Link building remained essential, but quality mattered far more than quantity. Guest posting on reputable sites, creating shareable resources, earning press coverage, and building partnerships were preferred over spammy link schemes.
Step 11: Optimize for Local Search
Local businesses optimized Google My Business listings, now called Google Business Profile, gathered reviews, and ensured consistent name, address, and phone information across directories.
How 2018 SEO Practices Apply Today
Many 2018 best practices have become baseline requirements. Mobile-first indexing now applies universally. HTTPS is standard. Page speed evolved into Core Web Vitals. Expertise and trust expanded into E-E-A-T, adding firsthand experience. Featured snippets and voice search paved the way for AI-generated answers and Generative Engine Optimization. Websites that adopted these practices in 2018 built foundations that still support rankings today.
Conclusion
Adding SEO into a website in 2018 meant embracing mobile-first design, HTTPS security, fast page speed, quality content, structured data, and ethical link building. These principles responded to major changes in how Google evaluated websites, and they remain fundamental today. Whether you are updating an older site or building a new one, applying these proven practices creates a strong foundation for long-term search visibility.
