A case study of merging two sites into one self-written resource in Python with saving the results

Initial situation

At the time of the beginning of the cooperation, the business had two separate websites that operated in parallel. At first glance, this did not seem critical, but in practice it created a number of serious obstacles:

• web resources competed with each other for targeted queries in search results;
• Google perceived the sites as affiliated, which hindered organic growth;
• the resources worked on Prom and OpenCart, which meant that the technical optimization of the site was significantly limited;
• the budget was divided between two different domains, instead of reinforcing one powerful resource.

In fact, the company invested time and budget in the development of two areas, neither of which revealed its real potential and did not bring the expected indicators. Due to the dispersion of domain authority and marketing investments, the sites worked in contradiction with each other. We proposed to consolidate all the potential in a single project, which would become the main source of organic traffic and sales, opening up opportunities for effective promotion of the site on Google.

SEO website promotion: comprehensive preparation for project launch and architectural planning

Work on the project began in February 2025 with the formation of the architectural foundation of the future resource. We adhere to a strategy in which development never begins with a visual concept or writing code. Instead, the first step is to build a site structure that takes into account:

• search demand logic and semantic core;
• opportunities for further scaling of the product catalog;
• designing targeted landing pages;
• current technical requirements and Google recommendations;
• ensuring a high level of convenience for users.

Only after final approval of the architectural model are design and development teams involved in the implementation of the project.

Why did the migration take several months?

Launching a new version of a resource is a complex, multi-level process that goes far beyond simply transferring product lines. To ensure a successful transition, we implemented three large-scale stages:

Before starting the technical migration, it was critically important to determine which of the two existing domains would become the main one, and which would be decommissioned with a 301 redirect. This strategic decision did not allow for chance, as it was the chosen domain that would inherit the accumulated SEO potential, becoming the foundation for the further development of the project.

In order to make an informed decision, our team conducted a comprehensive analysis of both resources, taking into account the following criteria:

• history and level of domain authority;
• current organic visibility and positions in Google search engine;
• volume and qualitative structure of organic traffic;
• index of pages in search engines;
• high-quality external link profile;
• current technical condition of resources;
• prospects for further scaling the project.

Based on a detailed analysis of all these indicators, a domain was selected that formed the basis of a new self-written Python website.

Domain with Opencart

Domain from Prom

Based on the analysis of data from Google Search Console over the past three months, it was decided to use the domain that was previously based on Opencart, as it demonstrated better performance. For the second resource, we developed a detailed redirect map and implemented a 301 redirect, which allowed us to transfer the accumulated "weight" as efficiently as possible, preserve organic traffic, and minimize the risks of losing positions in search results.

Only after all technical stages were completed on October 29, 2025, the new site, developed in the Python programming language, was opened for indexing by search engines. On the working resource, we finalized the implementation of all preparatory settings necessary for a stable start, in particular:

• implementing a redirect map (URL-to-URL) to preserve accumulated relevance and results;
• setting up a global redirect from one domain to another;
• creating a correct robots.txt file for proper crawling budget management.

This systematic approach allowed us not only to merge two sites, but also to consolidate all the existing SEO potential of the business into a single resource, laying a solid foundation for its further scaling.

The most important result: maintaining SEO

The first 2–3 months after launching a new resource are critically important, as it is during this period that search engines conduct an in-depth analysis of the updated site:

• a full reindexing of pages and checking the correct operation of 301 redirects are performed;
• The updated structure and its compliance with the historical data of the previous site are evaluated.

During this time, there may be slight fluctuations in positions or organic traffic volumes - this is a natural reaction of Google algorithms to large-scale changes. With a properly executed migration, the search engine gradually transfers the accumulated authority of the old resource to the new one, after which key indicators stabilize and show growth.

This is the stage that causes the most fear among business owners. The main fear is the risk of losing positions earned over years, as well as organic traffic and sales, which are often the main source of a company's income.

These fears are quite justified, because critical errors during migration — incorrect redirect settings, chaotic changes to the URL structure, loss of pages, or lack of control over the indexing process — can lead to a significant drop in the visibility of the resource in Google, a reduction in traffic, and, as a result, a decrease in the number of orders.

That is why professional SEO migration does not end on the day of technical launch. After the release, our team continues daily monitoring of indexing, analyzes the behavior of search robots, promptly eliminates technical inaccuracies and tracks the dynamics of positions. Only such comprehensive support allows you to go through the adaptation period as painlessly as possible and preserve all the acquired business results.

Organic visibility metrics (2 weeks before release)

Traffic dynamics analysis (2 weeks after release)

During this period, Google re-analyzes the resource architecture, gradually re-indexing pages and testing their current relevance. The most important result of this stage was that:

• organic traffic volumes remained stable;
• search engine impression indicators have been preserved;
• The resource retained its ranking for targeted commercial queries.

After the migration was completed, our team continued the comprehensive development of the project, combining SEO website promotion , Google Ads tools, and constant technical monitoring of the new resource.

At the same time, it is important to understand that the first month after launch is not the result of just 28 days of work. This is clear evidence that during the migration we managed to preserve the accumulated authority, organic visibility, and SEO potential of two separate sites, successfully consolidating them into one resource.

Over the past 28 days, the main indicators of the site's performance in organic search results show the following results:

• Clicks: 2.41 thousand clicks were recorded on the site.
• Impressions: The total number of impressions of the link in search results is 42.9 thousand.
• CTR: The average click-through rate is 5.6%, which reflects the proportion of impressions that resulted in a targeted click.
• Average position: the site maintains an average position in search results at level 20.

It was the preservation of these metrics after a large-scale migration that became key confirmation that the transition to a new self-recording resource was implemented correctly and without critical losses for the business.

Dynamics of positions for key queries in search results

The data provided confirms the relevance of the resource in search results for key queries in November 2025.

According to the results of the first month of operation of the new resource, the following indicators were achieved:

• total income: 766,876 UAH;
• total number of transactions: 136 purchases.

Share of organic search in the total result:

• number of orders: 57;
• income: 342,517 UAH.

The data provided serves as proof that strategically correct migration allowed not only to preserve previously accumulated potential, but also to lay an effective foundation for further scaling of the business.

Metrics Analytics: Why Integrated SEO and Google Ads Work Is Key to Revenue Growth

Summing up the results of the work for the first six months of 2026, it is worth analyzing what indicators were achieved after the successful adaptation of the resource.

The presented graph clearly demonstrates that after launching the updated resource, we managed not only to preserve the accumulated SEO potential, but also to ensure its further positive dynamics.

The first weeks after the migration were an adaptation phase for search engines: Google re-indexed pages, analyzed the updated architecture, and gradually transferred “weight” from old URLs to new ones. This is a completely natural process after any large-scale migration.

The graph has been showing a steady upward trend since the beginning of 2026. The steady growth in organic traffic and the number of impressions is a direct confirmation of the correctness of the technical migration, the correct indexing settings, and the consistent strengthening of the resource's authority in search results.

Most importantly, the new self-written Python website not only successfully integrated all the developments of previous versions, but also gained significantly higher potential for scaling. It was the high-quality architecture, correct data transfer, and comprehensive SEO promotion of the site from the Golden-Web Digital team that became a reliable foundation for the stable growth of visibility and commercial indicators of the business.

According to the results of May 2026, key performance indicators of the resource demonstrate stable growth in commercial results:

• total income: 1,293,866 UAH;
• total number of transactions: 206 purchases.

Effectiveness of engagement channels:

• Organic search:
  • number of sales: 60;
  • income: 345,941 UAH;
• Google Ads:
  • number of sales: 105;
  • income: 673,924 UAH;

These data clearly confirm the effectiveness of the chosen development strategy and professional approach to resource optimization.
