Client: S-Sawasdee Plastic Thailand
Project: SEO-Driven Website Optimization for Plastic Bag Manufacturer
Website: ส-สวัสดีพลาสติก.com
S-Sawasdee Plastic Thailand is a trusted plastic bag manufacturer with over 25 years of experience, specializing in garbage bags, color-coded bags, and OEM services. The company aimed to increase online visibility and generate more leads organically through a robust SEO strategy, helping them reach both business clients and end consumers.

Prior to implementing a structured SEO strategy, the website had low visibility on Google Search with minimal clicks and impressions. It was not ranking on the first page for key search terms such as “ถุงดำ” (black garbage bag) or “ถุงขยะสี” (colored trash bags), which are highly relevant to the brand’s core offerings.
To address this, the challenge was twofold:
Increase organic traffic and improve keyword rankings in a competitive search environment.
Prepare the website for modern AI-driven search experiences by implementing both AEO (Answer Engine Optimization) to ensure that search engines and AI tools can understand and directly serve answers from the site and GEO (Generative Engine Optimization) — to enhance visibility for users searching from specific locations like Thailand.
These optimizations aimed to position the website not only for traditional keyword-based search, but also for AI search tools, voice assistants, and smart queries that prioritize structured, localized, and easily indexable content.
Digital Agency Bangkok provided a comprehensive SEO,AEO&GEO strategy along with technical and structural website enhancements to support long-term search visibility.
SEO-Friendly Website Structure Organized product categories for easy navigation (black bags, color-coded bags, OEM, etc.)Optimized URLs and title tags for each section Created targeted landing pages for different product types
Content Writing for SEO Published educational blog content on HDPE, LDPE, and LLDPE plastic bags Focused on high-intent, high-volume keywords relevant to the industry
On-Page Optimization & Technical SEO Improved meta titles and descriptions for better CTR, Enhanced page speed and ensured mobile responsiveness
Monthly SEO Reporting & Monitoring Regular tracking of total clicks, impressions, and keyword ranking progress, Comparative reporting from February to July to measure real growth
AEO & GEO Integration for AI-Based Discovery
AEO (Answer Engine Optimization) was implemented to help the website be easily understood and surfaced by AI-powered tools like ChatGPT, Google featured snippets, and voice search assistants.
GEO (Generative Engine Optimization) was applied to optimize content for emerging generative AI platforms that prioritize well-structured, localized information.
These enhancements ensure that the website can appear not only in traditional search results but also in AI-generated responses — increasing its chances of being discovered through next-generation search tools.




From February to July, the SEO performance showed consistent improvements:
Following the implementation of structured SEO, AEO (Answer Engine Optimization), and GEO (Generative Engine Optimization), the S-Sawasdee Plastic website began appearing as a recommended source when users queried AI platforms including ChatGPT for trash bag manufacturers in Samut Prakan, Thailand.
This highlights the success of optimizing not only for traditional search engines, but also for next-generation, AI-powered discovery tools.
