Five years ago, I concluded my college internship at Numrex by writing a blog post titled My Experience in Digital Marketing. At the time, I confidently claimed, “In my six weeks, I’ve learned more about digital marketing than in my entire three-year program.” Looking back, it’s funny to realize how little I understood about the vast world of SEO. Since then, both my career and the SEO industry have undergone incredible transformations. What seemed like a solid foundation back then was actually just the beginning of a journey filled with continuous change, new challenges, and valuable lessons in SEO.
The Evolution of SEO at Numrex: From Humble Beginnings to Industry Leader
When I started at Numrex, the company was much smaller—fewer than 10 people crammed into a couple of rooms in the U-Haul building near Pinecrest Road in Ottawa. Super glamorous, right? Fast forward to today, and our current office in Lansdowne boasts free snacks, coffee, and modern amenities. But back in those U-Haul days, it was strictly BYOS (Bring Your Own Snacks). I often wonder what new employees would think if they teleported back to those humble beginnings without context.
Looking back, it’s clear that SEO and startups share one undeniable trait: constant evolution. From small beginnings to something greater, both are defined by change, adaptability, and growth.

The SEO Landscape in 2020: A Different Game
In 2020, SEO was a completely different ball game. If I had to sum it up in just two words, they’d be “Keywords Everywhere.” Exact match keywords were overused, resulting in spammy pages that would make any modern SEO cringe. But back then, this was still an effective strategy, so we all played along.
Link building was also different. It wasn’t about building relationships or earning organic links. Instead, it was the era of link farms and directory submissions—getting listed on as many low-quality directories as possible was considered strategy. This eventually led to Google cracking down on such tactics with updates like Penguin.
Internally, our SEO approach at Numrex was a far cry from what it is today. We used tools like Agency Analytics for keyword tracking and monitoring, but our workflow was reactive. When rankings dropped, we’d make on-the-fly changes to try to recover. Although this approach worked, it lacked transparency. There was little communication with clients about what was being done and why.
As time passed, we refined our SEO process. We created structured action plans and made education a core part of our client relationships. This evolution not only improved our effectiveness but also strengthened trust and deepened the understanding of SEO’s value.

Major Shifts in SEO: How Google’s Algorithm Updates Transformed the Industry
SEO didn’t just evolve over the years—it reinvented itself. Major algorithm updates shaped SEO practices, and we had to adapt quickly to stay ahead. Let’s dive into the major shifts that reshaped SEO between 2016 and 2024.
RankBrain introduced AI and machine learning to Google’s algorithm, marking a shift from keyword-focused SEO to content that answers user questions and context.
Mobile-First Indexing prioritized mobile versions of websites for ranking, reflecting the growing importance of mobile search over desktop search.
BERT improved Google’s understanding of natural language, emphasizing content aligned with user intent over simple keyword targeting.
Core Web Vitals became a ranking factor, underscoring the importance of user experience—things like page load speed, interactivity, and visual stability—now directly impacted rankings.
The Helpful Content Update focused on rewarding genuinely helpful, user-focused content while targeting low-quality, AI-generated material.

Key SEO Lessons: What We’ve Learned Over the Years at Numrex
As the SEO industry has evolved, so have the lessons we’ve learned at Numrex. Here are a few that have stood the test of time:
- SEO is User-Centric: Websites that prioritize a seamless user experience are likely to rank higher. Google’s focus on user experience means that website structure, easy navigation, and usability are essential for SEO success.
- Intent Matters More Than Keywords: While keyword research is crucial, it’s more important to understand user intent behind those keywords. Analyze search engine results pages (SERPs) to see what type of content is ranking for your target keywords, and match that intent.
- Keyword Stuffing Is a Thing of the Past: Google has become much smarter at detecting keyword stuffing. Now, SEO focuses on creating valuable content that naturally incorporates relevant terms. FAQs are a great way to answer common questions while naturally including strong keywords.
- Site Speed and Core Web Vitals Are Critical: A slow website not only frustrates users but can negatively impact rankings. Optimizing image sizes, reducing server response times, and addressing Core Web Vitals issues are essential for keeping rankings up and ensuring a good user experience.
SEO Fundamentals That Remain Unchanged at Numrex
While SEO practices are constantly evolving, some elements have remained crucial over the years:
- Title Tags, Meta Descriptions, and Header Tags: These elements continue to help search engines understand your content. While keyword strategy has evolved, on-page SEO fundamentals still play a key role.
- Backlinks Are Still King: Although Google’s algorithm has become more sophisticated in detecting manipulative link-building practices, high-quality backlinks from authoritative sites remain one of the most important ranking factors. Quality over quantity is now the name of the game.
- Technical SEO is Still Essential: Ensuring your site is crawlable and indexable by search engines is still a foundational element of SEO. Mobile optimization, clean URLs, and site structure continue to play a critical role in your SEO success.
Navigating the Future of SEO: Staying Ahead of Trends
SEO is always in flux, and staying adaptable is key. Over my 8 years in the industry, one lesson has been abundantly clear: embracing change is crucial. Whether it’s algorithm updates or new SEO tools and tactics, adaptability is the best strategy for long-term success.
Future SEO Trends: AI, Automation, and Beyond
AI and automation are rapidly transforming SEO. Google’s continued push for content that matches user intent means AI-powered tools will likely play an even bigger role in SEO strategies. However, staying true to SEO best practices and understanding your audience will always remain critical to avoiding drastic drops during algorithm updates.
Final Thoughts: The Path Forward in SEO at Numrex
In conclusion, SEO will always be defined by change, and that’s what makes it so exciting. Whether you’re new to the industry or a seasoned pro, remember that continuous learning, adaptability, and a user-first approach are key to staying ahead. The road ahead may be unpredictable, but if you stick to solid SEO principles, you’ll be well-equipped for success.
