Sunrise Restoration needed more qualified leads from search while competing against larger franchises with stronger local SEO. The site also lacked clear service messaging, location signals and trust-building content.
Solution
We migrated the site to Squarespace so the team could manage updates more easily, rebuilt the design around an Arizona-inspired visual direction and created a lightweight brand system. We then ran local keyword research, improved technical SEO, added schema and set up conversion tracking in Google Tag Manager for calls and form submissions.
Result
In 90 days, Sunrise Restoration increased organic search sessions by 907%, page views by 897% and keyword rankings by 646%. The campaign also drove a 389% increase in tracked conversions.

Organic growth plateaued because search engines could not easily prioritize the brand’s highest-value pages. Crawl budget was being wasted, overlapping content created confusion and the ecommerce structure was harder to interpret.
Solution
We audited the root domain, cleaned up the XML sitemap and removed low-value pages to reduce crawl waste. We consolidated overlapping content, improved Shopify product pages with better keyword targeting, clearer heading structure and stronger schema, then strengthened internal linking and launched a high-intent comparison pillar.
Result
The campaign drove 820% growth in monthly organic search revenue, a 95.87% increase in organic search sessions and a 200.5% increase in organic shopping sessions. It also improved average Google rankings from 14.53 to 9.78 and increased LLM-generated revenue by 17,205%.

Factor lacked SEO-optimized pages tailored to customers searching for specific diets like keto and Paleo. Their CMS further limited scalable, high-performing page creation for each diet vertical.

Result
Factor increased organic search revenue by 273%, organic search traffic by 248% and monthly organic sessions by 191K. The campaign also drove a 13% lift in top-three ranking keywords and a 63% increase in total ranking keywords.
