PacRes Mortgage came to us with a clear goal: increase organic traffic, improve search rankings for key loan-related terms, and generate more qualified leads through their website. Despite being a well-established lender, their online visibility was falling short of their market presence. Competing in a crowded financial services landscape, they needed an SEO strategy that would set them apart—both locally and nationally.
Solution
We started with a full SEO audit to uncover technical issues and content gaps. Our strategy included improving site speed, fixing crawl errors, enhancing mobile usability, targeting high-intent mortgage keywords, optimizing metadata and internal linking, creating helpful content, boosting local SEO for branch pages and Google profiles, and tracking results with GA4, GSC, and SEMrush for ongoing reporting.
Result
In six months, PacRes saw a 92% boost in organic traffic, 75% more lead form submissions, and top 3 rankings for key mortgage terms. Visibility improved across all major lending pages and locations. This success came from close collaboration, a custom SEO plan, and a focus on attracting qualified leads—not just traffic—by aligning content with what users were actively searching for.

Vic’s 66, a well-established auto parts retailer, had built a strong online presence over the years, with a steady stream of orders coming in every hour. However, after launching a newly redesigned WordPress website, their business took a drastic hit. What was once a thriving eCommerce operation saw its order volume plummet from several orders an hour, to several orders a week!
Solution
To restore traffic and sales, we conducted a full SEO audit, fixed broken redirects, optimized metadata, and improved site speed. We submitted a revised sitemap, ensured proper indexing, and rebuilt internal links. By resolving these technical issues and restoring search visibility, Vic’s 66 regained its rankings and eCommerce revenue.
Result
Went from getting 1k visitors a month when we first engaged, back to their initial traffic numbers of 5,000 a month, and with us continually growing their strategy, they now receive over 7,000 visitors a month!

The hot air balloon tourism market in Teotihuacan was saturated with over 40 operators competing for the same high-converting keywords. Customers were arriving fragmented across multiple companies with no clear positioning. The challenge: to position not one, but multiple brands from the same niche on the first page of Google without them cannibalizing each other, while building individual authority for each domain in a market where everyone essentially offered the same service.
Solution
Differentiated semantic architecture for each site with unique ranking angles. Individual topic maps and specialized Schema markup for each type of offer. Content optimized for featured snippets and AI Overviews. Unified technical SEO: Core Web Vitals, mobile-first, clean URLs. Local strategy with location-optimized Google Business Profile. Proprietary method to prevent keyword cannibalization between domains in the same niche.
Result
13 pages simultaneously ranking on the first page of Google for the niche's main keywords. Absolute SERP dominance with positions 1-10 under control. Average increase of 340% in organic traffic per site. 70% reduction in reliance on Google Ads. First sites in the sector to appear in AI Overviews and be cited by ChatGPT and Perplexity for tourism queries in Mexico.

A B2B services company with no presence on generative search engines. When users asked ChatGPT, Perplexity, or Google AI Overviews for solutions in their industry, the competition appeared, but they didn't. They were missing business opportunities in a channel their competitors didn't yet understand. They needed to establish a presence in this new ecosystem before the market became saturated.
Solution
Implementation of a complete GEO (Generative Engine Optimization) strategy. Content restructuring to answer specific buyer journey questions. Advanced schema markup for entities and relationships. Architecture optimization to reduce extraction costs for LLMs. Creation of citable content using proprietary data and a unique methodology. Management of brand presence across sources that feed language models.
Result
Brand consistently cited by ChatGPT in relevant industry queries in under 90 days. Featured in Google AI Overviews for 12 top business keywords. Share of voice in AI responses increased from 0% to 34% in its category. 28% increase in qualified leads attributed to referral traffic from generative AI platforms. Positioned as an industry leader in the new search ecosystem.
