SEO advice is easy to publish. Evidence is harder to find.
A case study can show what a company changed, what happened afterward, and which lessons might apply to another website. However, not every case study proves that one SEO change caused all the reported growth.
The examples below come from published company or Google Search Central case studies. Treat the numbers as reported results, not guaranteed outcomes.
1. Saramin: Organic traffic doubled during peak hiring season
Source: Google Search Central case study
Saramin, a major Korean job platform, began using Google Search Console in 2015. The company initially focused on crawling errors and gradually expanded its SEO work.
Google’s case study reports that Saramin’s early technical work increased organic traffic by 15%. After further improvements, organic traffic from Google Search grew by 102% year over year during the September 2019 hiring season. The company also reported a 93% increase in new member sign-ups from organic search.
What SEO professionals can learn: Start with crawlability and indexing problems before investing heavily in new content. Fixing existing issues can create value, especially on large websites.
2. MX Player: More than 3x growth in Google traffic

MX Player improved video discoverability by implementing structured data and submitting video sitemaps more frequently.
Google’s published case study reports more than three times the traffic from Google over six months, alongside a 100% increase in video page views per session from organic search.
What SEO professionals can learn: Websites with large video libraries need a video-specific SEO strategy. Video indexing, structured data, and sitemaps can help search engines understand the content.
3. Monster India: Better visibility for job listings
Source: Google Search Central case study
Monster India introduced JobPosting structured data to help its job listings appear in Google’s job search experience.
The published results reported a 94% increase in organic traffic to job detail pages and a 10% increase in applications.
What SEO professionals can learn: Structured data can support eligibility for specific search features. It is most useful when the markup accurately describes the page and follows Google’s guidelines. It does not guarantee enhanced visibility.
4. ZipRecruiter: Organic traffic that converted better
Source: Google Search Central case study
ZipRecruiter added structured data to job listings and participated in Google’s job search experience.
Its case study reported that the conversion rate from Google organic traffic to job pages was more than 4.5 times higher than before. The company also reported 35% more monthly non-branded organic traffic.
What SEO professionals can learn: Traffic volume is not the only useful SEO metric. A search feature that sends more relevant visitors may improve business outcomes even if it does not deliver the largest number of clicks.
5. Rakuten: Structured data and recipe engagement

Rakuten’s recipe platform implemented structured data to help Google understand recipe content.
Google’s case-study collection reports that the work was associated with 2.7 times more traffic from search engines and 1.5 times longer average sessions.
What SEO professionals can learn: Structured data should be part of a broader plan to help users discover and understand content. The results from a recipe platform may not translate directly to a B2B website or online store.
6. Eventbrite: Improving event discovery

Eventbrite used event structured data to help Google understand event information.
The published case study reported that year-over-year growth in Google traffic to event pages roughly doubled in the month following the launch of the enhanced search experience.
What SEO professionals can learn: Websites with time-sensitive information should ensure that dates, locations, and other key details are accurate and machine-readable. Event markup is only useful when the page meets the relevant requirements.
7. Jobrapido: Making job listings easier to discover
Source: Google Search Central case studies
Jobrapido implemented job-related structured data to make its listings eligible for Google’s job search experience.
The case appears in Google’s official case-study collection, which documents how job sites used structured data to improve organic discovery.
What SEO professionals can learn: For websites with thousands of similar pages, scalable technical implementation matters. A template-level improvement can affect many URLs, but the quality and accuracy of each listing still matter.
8. Vimeo: Making video content easier to understand
Source: Google Search Central case studies
Vimeo used structured data and video SEO practices to help Google understand video content, including opportunities related to key moments.
What SEO professionals can learn: Video SEO involves more than adding a video to a page. Search engines need to understand the video, its page context, and the relevant metadata. The correct implementation depends on how videos are hosted and embedded.
9. Wix: Integrating SEO capabilities into the platform
Source: Google Search Central case studies
Google’s Wix case study explains how Wix integrated Google APIs and Search Console-related functionality, including sitemap submission and URL inspection.
What SEO professionals can learn: SEO platforms can reduce the work required to manage technical tasks. However, an easier workflow does not automatically mean a website will rank better. Implementation quality and content remain important.
10. Cross-regional video publishers: Improving video search visibility
Source: Google Search Central case studies
Google’s case-study collection describes how three global publishers used video SEO practices and Search Console reports to improve their reach.
What SEO professionals can learn: For international websites, technical consistency across regions is important. Video metadata, indexing, and reporting should be checked across relevant versions of a site, not just the homepage.
11. Lana Skyn: Organic traffic and bookings after a website change
Source: Wix Studio SEO Hub case study
A Wix-published case study describes how Lana Skyn, a beauty clinic in Amsterdam, moved from Squarespace to Wix and later integrated Wix Bookings.
The case study reports organic traffic increasing from 135 to more than 2,000 monthly visitors, while monthly bookings rose from 3 to 35. The project also included a change to the booking system, so the reported results should not be attributed to SEO alone.
What SEO professionals can learn: Traffic reports are more useful when connected to conversions. A website migration, improved content, and a better booking journey can all contribute to business results.
