Advanced SEO optimization
ASSIST redesigned and rebuilt the ZeroBounce website with a custom WordPress theme, optimizing key sections for performance, usability, and search engine visibility. Initially scoring 40% in SEO performance, the website now achieves near-perfect 100% optimization across most tools, significantly boosting its search rankings and user experience.
To maximize both speed and SEO efficiency, we implemented a hybrid approach, leveraging React for a modern, dynamic interface while utilizing Gatsby for deployment. This allows for server-side rendering (SSR), transforming the site into a high-speed, SEO-friendly static React website—eliminating the performance and indexing issues common in traditional React builds.

The ZeroBounce Blog Experience
ZeroBounce blog is a standalone web application which provides multiple features for its readers. The user can either share an article, search a specific topic, filter the search, see featured articles, or subscribe to notification letters. All articles are accessible to the end users and the blog search engine is continuously optimized.
The blog has a new theme deployed, aligned with the one on the official website and benefits from the same SEO performance. For this, a continuous maintenance process is needed. Currently, the blog contains articles and news that are classified in corresponding categories, for both professional development and insights on the ZeroBounce company.

Frequently Asked Questions
1. What is ASSIST Software's development process?
The Software Development Life Cycle (SDLC) we employ defines the following stages for a software project. Our SDLC phases include planning, requirement gathering, product design, development, testing, deployment, and maintenance.
2. What software development methodology does ASSIST Software use?
ASSIST Software primarily leverages Agile principles for flexibility and adaptability. This means we break down projects into smaller, manageable sprints, allowing continuous feedback and iteration throughout the development cycle. We also incorporate elements from other methodologies to increase efficiency as needed. For example, we use Scrum for project roles and collaboration, and Kanban boards to see workflow and manage tasks. As per the Waterfall approach, we emphasize precise planning and documentation during the initial stages.
3. I'm considering a custom application. Should I focus on a desktop, mobile or web app?
We can offer software consultancy services to determine the type of software you need based on your specific requirements. Please explore what type of app development would suit your custom build product.
- A web application runs on a web browser and is accessible from any device with an internet connection. (e.g., online store, social media platform)
- Mobile app developers design applications mainly for smartphones and tablets, such as games and productivity tools. However, they can be extended to other devices, such as smartwatches.
- Desktop applications are installed directly on a computer (e.g., photo editing software, word processors).
- Enterprise software manages complex business functions within an organization (e.g., Customer Relationship Management (CRM), Enterprise Resource Planning (ERP)).
4. My software product is complex. Are you familiar with the Scaled Agile methodology?
We have been in the software engineering industry for 30 years. During this time, we have worked on bespoke software that needed creative thinking, innovation, and customized solutions.
Scaled Agile refers to frameworks and practices that help large organizations adopt Agile methodologies. Traditional Agile is designed for small, self-organizing teams. Scaled Agile addresses the challenges of implementing Agile across multiple teams working on complex projects.
SAFe provides a structured approach for aligning teams, coordinating work, and delivering value at scale. It focuses on collaboration, communication, and continuous delivery for optimal custom software development services.
5. How do I choose the best collaboration model with ASSIST Software?
We offer flexible models. Think about your project and see which models would be right for you.
- Dedicated Team: Ideal for complex, long-term projects requiring high continuity and collaboration.
- Team Augmentation: Perfect for short-term projects or existing teams needing additional expertise.
- Project-Based Model: Best for well-defined projects with clear deliverables and a fixed budget.
Contact us to discuss the advantages and disadvantages of each model.
