These case studies show different types of SEO work with direct implementation: from long-term, data-driven optimization and domain migration to content improvements, internal linking, and website performance.
Otkup Vagner — ongoing SEO optimization
Otkup automobila Vagner is a car-buying website for which the SEO engagement began in the first quarter of 2025 and has continued ever since. Unlike a one-time audit, this project shows what long-term SEO work looks like: the technical foundation is maintained, search data is monitored, existing pages are improved, and new content is created in response to real opportunities.
From a generic domain to a recognizable brand
The website originally operated on the otkupautomobila.biz domain. I proposed presenting the business under the name Vagner, taken from the owner's surname, and moving it to Serbia's national .rs domain. This replaced a generic address with a name the client can develop as a long-term brand: otkupvagner.rs.
A new technical foundation was established by moving the website to the Dozet WordPress theme. This provided a maintainable foundation that can continue to be changed and optimized without introducing a separate system solely for SEO.
Search Console, technical analysis, and content
Google Search Console was connected at the beginning of the engagement, before decisions about new articles were made. Its data shows which queries already surface the website, which pages have potential, and where more precise answers to real searches are needed.
An internal crawler was used to analyze the site's structure and find linking errors. The next step was correcting page links and improving internal connections so that visitors and search engines could reach important content more easily.
Existing copy is expanded and improved to cover each subject more thoroughly and increase its search visibility. New articles are not selected by guesswork: their topics are chosen after analyzing queries and pages in Search Console.
Keyword cannibalization analysis
The current phase is a keyword cannibalization analysis — identifying cases in which multiple URLs on the same website compete for identical or closely related searches. The analysis uses an internal tool and an AI coding agent, and its findings support decisions about clearer page targeting, internal links, content expansion, or consolidation.
The client is satisfied with the work to date. The continuity of the engagement since the first quarter of 2025 makes it possible to develop the SEO strategy in response to data and changes on the website instead of leaving it as a one-time report.
Drive Away — content, WordPress changes, and performance
The existing WordPress theme on the Drive Away driving school website needed to be adapted without compromising site stability. Completed in July 2024, the project involved 32 hours of technical and content work.
- theme and responsive-layout adjustments;
- launching a blog and preparing content for organic search;
- HTML and CSS changes for a clearer user experience;
- image and code optimization for faster loading.
This project is an example of treating SEO content, presentation, and performance as connected parts of the same website rather than separate tasks.
Resolving CLS and PageSpeed issues
In the second quarter of 2021, the task focused on a specific technical problem: cumulative layout shift, or CLS, while a page was loading. The issue affected Core Web Vitals data and the PageSpeed score, as well as visitors whose page content moved unexpectedly.
The work covered identifying the causes of the shifts, implementing fixes, and verifying the results with Google PageSpeed Insights and Search Console data. This is an example of focused technical optimization intended to resolve a measurable problem without making unnecessary changes elsewhere on the website.
Client feedback
★★★★★5/5“Dejan was a pleasure to work with. He's got a lot of experience and was a great communicator, providing lots of help and feedback. I've worked with a lot of Upworkers, can highly recommend him.”
Klik.co.rs — online store optimization
Klik.co.rs is the online store of a Belgrade company specializing in branded products. In December 2020, I carried out SEO optimization and repairs on the existing website without building a separate new system.
This older reference demonstrates work on a custom online store, while the Otkup Vagner case above shows how the same approach has developed into a long-term cycle of measurement, technical fixes, and content improvements.
