Customer purchased a new domain and setup his website through Wix. He wants to dominate his locale in Local and Organic search.
Solution
During the first month of the domain's existence, all Technical SEO issues that could be handled were hashed out. After that we performed keyword research & implementation, on page SEO tweaks, and copywriting as most pillar pages had thin content. We matched his main competitor in terms of word count per service page and that seemed to pay off rather well!
Result
After 3 months and solid SEO work, this domain is out of the Google Sandbox and rivaling their main competitors - overtaking them in one city as the #1 auto body shop. Clicks up 77%, Impressions up 96%, and Organic Searches grew 4,357%, and Organic Traffic grew 100%, Organic Keywords up +417% - all in 90 days.

Customer had a limited budget, but still wanted to see what kind of SEO work she could get for her outdoor preschool website. She is based in Raleigh, North Carolina so there is a significant amount of competition she is up against. At the time of talking, I could not find her within the Top 100 for "outdoor preschools" in Raliegh.
Solution
After performing a quick analysis, there were items that needed attention across all three SEO realms (Technical SEO, On Page SEO and Off Page SEO). I agreed to four hours of solid work that included Technical SEO, On Page SEO and Off Page. Corrected a major Technical SEO issue (duplicate H1 tags) On Page included some basic keyword research & implement to her Meta TItle & Description, page titles, & alt image tags. Off Page included teaching her the value of Google Reviews and some Local SEO
Result
After a month, her impressions began to rise and clicks began to come in. She was not in the Top 100 before, now she is sitting in page 3 for "outdoor preschools" in Raliegh. There is still more work to go, but she was happy that she had generated a few leads via the work I did. We will continue to work for this client as their budget allows!

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!

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.
