Company Introduction

Jiangneng Digital Marketing is based in Taipei, but I also saw their Taichung office, so I included it in the comparison. Founded by the renowned teacher Lien Chi-yu, Jiangneng Digital Marketing focuses on search engine optimization, uses WordPress for its website ranking, and provides training courses and consulting services. It is a long-established marketing company.

SEO capability analysis

In addition to providing SEO services, we also assist clients in setting up websites with WordPress. Our company website is also built with WordPress. We also provide training services, full-page promotion services, and video optimization. WordPress has many external resources available for SEO, and website performance also requires external optimization. In the case study, we saw that we helped clients write articles and build external links. After testing, the overall performance of the website architecture was at a medium level.

PSI performance test results fall into the middle range

SEO Case Analysis

Jiangneng Digital Marketing Co., Ltd. boasts 16 successful SEO case studies. While the number is relatively small, it still demonstrates considerable SEO expertise. This company likely possesses specialization in certain areas or industries and can provide effective SEO services to clients, demonstrating a solid foundation of experience. Several of the successful cases have been verified to have yielded substantial results.

Company Introduction

Wei Hong is a well-established marketing company in the market, offering a wide range of marketing solutions. They are often seen in SEO services, primarily targeting B2B clients, and have also invested heavily in international marketing techniques for website development.

SEO capability analysis

Because there were no successful case studies for testing, we used website design case studies. The website's architecture was tested and found to be decent, falling into the medium range. However, since there were no case studies, we could only evaluate the official website, which had about 30 articles shared. It seems that the focus was mainly on B2B, so there were no obvious marketing articles.

PSI performance test results fall into the middle range

SEO Case Analysis

Weihong Technology Co., Ltd. does not provide any SEO success stories. This may indicate that the company has no publicly available case studies in SEO services, and the reason for this is unclear. For clients seeking SEO services, the lack of publicly available case studies increases the difficulty of assessing their capabilities and experience. Interested clients are advised to proactively contact them to further understand their professional capabilities and practical experience.

4. Orion Digital Information Co., Ltd.

• Address: 9F-11, No. 262, Section 2, Henan Road, Xitun District, Taichung City

Furthermore, they can develop customized programs to meet your specific needs, creating exclusive solutions to make your digital business more efficient.

SEO capability analysis

Ou-Yao provides website design, architecture optimization, and link optimization services. Content writing is AI-assisted, but there is no free health check or success story information. The website architecture can only be tested on the official website and the client's website. The official website's architecture is low-level, while the client's is mid-level. Because there are no SEO success stories, not many details can be known. The official website itself does not have much traffic, so the information is unclear.

PSI Performance Test Score

SEO Case Analysis

Ouyao Digital Information Co., Ltd. did not provide any SEO success stories, similar to the situation with Weihong Technology, indicating that the company may not have publicly available case studies in the SEO field. This is a crucial indicator for clients evaluating SEO services; without publicly available case studies, their practical SEO experience and effectiveness cannot be effectively verified. It is recommended that interested parties further investigate the company's core services and technological advantages.

5. Arno Marketing Planning Co., Ltd.

• Address: 3F-3, No. 137, Section 1, Huamei West Street, West District, Taichung City

Company Introduction

Arno Marketing offers a variety of online marketing services, primarily helping businesses increase their online exposure and customer inquiries. Through search engine optimization (SEO), they help website content rank naturally at the top of search engines such as Google, attracting more potential customers.

SEO capability analysis

Arno Marketing's own website doesn't have much traffic, so its capabilities aren't apparent. However, Dongxing Pawnshop is definitely a successful case study, with a large output of articles. Both Arno and Dongxing Pawnshop are websites built with WordPress and use SEO plugins, resulting in relatively low architecture efficiency. Their official websites typically have around 50-60 articles, all of which are based on legitimate SEO practices.

PSI performance test score

SEO Case Analysis

Arno Marketing Planning Co., Ltd. has three successful SEO cases, which is relatively few and may indicate a lack of experience in the SEO field. However, despite the limited number of successes, it at least demonstrates their ability to complete certain SEO projects. If considering collaborating with them, it is recommended to thoroughly understand the specific details of their SEO work, their operational strategies, and client feedback to assess the quality and potential of their SEO services.

SEO capability analysis

They provide many success stories. After analyzing the architecture, it is of medium quality (around 50). They all use WordPress + writing articles for SEO, and the backlink ratio is also very appropriate. The company is good at executing regional keywords, especially pawnshops and clinics.

PSI Performance Test Results

SEO Case Analysis

Wango Network Technology Co., Ltd. boasts 34 successful SEO cases, a number that falls into the upper-middle range in this analysis, demonstrating its considerable experience and strength in the SEO field. Wango has numerous cases in pawnshops and clinics, as can be seen on its website, all featuring the region + keyword, indicating their expertise in regional keyword targeting.

7. Ouken Information Marketing Co., Ltd.

• Address: 14F-1, No. 716, Zhongzheng Rd., Zhonghe Dist., New Taipei City

Ouken primarily provides a diverse range of online marketing services, from building professional websites and performing search engine optimization (SEO) to executing content marketing and search engine marketing, helping clients increase online exposure and business growth. They also offer website collaboration projects and specialize in promotion in the German B2B industrial market.

SEO capability analysis

Because there are no successful SEO case studies, the official website and website design examples were used for testing. The architecture score was low. Since there are no successful case studies, we can only observe the official website. It has 20 articles, which are more focused on the latest news and not SEO logic. The official website does not have much traffic at present. It is difficult to judge its SEO capabilities in terms of architecture, content and links.

Website architecture performance testing

SEO Case Analysis

Ouken Information Marketing Co., Ltd. has not publicly disclosed any SEO success stories, and its website does not describe specific results or experience regarding its SEO services. When selecting an SEO provider, the lack of comparable case studies makes it impossible for clients to assess their professional capabilities and execution effectiveness based on past results, requiring more time for background checks and risk assessments. Because it is impossible to further understand their actual SEO strategies and results, we recommend conducting a more in-depth understanding and confirmation with your company before cooperating.

8. Chuanliu Information Technology Co., Ltd.

• Address: 12F-9, No. 925, Section 4, Taiwan Boulevard, Xitun District, Taichung City

They offer customized solutions and quarterly reports to help clients monitor their marketing performance at any time.

SEO capability analysis

The official website has low traffic and is a one-page website. One-page websites cannot be used for SEO ranking because there are no successful SEO case studies and the official website has no references. PSI is not a reference for one-page websites. In addition, there are no articles available, so it is impossible to analyze its practical SEO capabilities.

PSI Test Results (One-Page Website)

SEO Case Analysis

Chuanliu Information Co., Ltd. does not provide SEO success stories, similar to other companies that do not publicly disclose them. This indicates that their experience in the SEO field may not be publicly available or showcased. Clients should consider this as an important factor when evaluating their services and proactively inquire about the team's professional background, service processes, and whether there are any undisclosed success stories available for reference. Without provided case studies, we cannot assess the effectiveness of these client case studies.

9. Elio Network Information Co., Ltd.

• Address: 18F-1, No. 566-1, Section 2, Wenxin Road, Hecheng Village, Xitun District, Taichung City

• Web design: Yes
• Architecture optimization: Yes
• Article written by: None
• External connections: Yes
• Service type (consulting/performance): Consulting

Company Introduction

This company primarily provides diverse website design services, ranging from website style planning and visual design to backend program management system construction, as well as customized services such as online payment systems and restaurant reservation systems. They also offer hosting and regular security scans to ensure smooth and secure website operation for their clients.

SEO capability analysis

The website's architecture is average, scoring around 60 points. Random testing with client design cases yields a score of around 50 points, which is also average. Since there are no successful SEO case studies, the SEO techniques can only be observed from the dozen or so articles on the website, which are fairly standard. Due to the lack of practical case studies, it is difficult to judge its SEO capabilities.

Website performance test results

SEO Case Analysis

Ailiou Network Information Co., Ltd. does not provide SEO success cases and lacks practical case sharing in its SEO services. For clients who need professional SEO services, choosing a company without publicly available success cases carries a high degree of uncertainty. It is necessary to evaluate the professional capabilities of SEO companies through other means, because without case studies, it is impossible to examine the client's keyword performance.

10. Taiwan Langfeng International Enterprise Co., Ltd. (Wanzhihui)

• Address: 20th Floor, No. 186, Zhengshi North 7th Rd., Xitun District, Taichung City

Company Introduction

Wanzhihui provides digital marketing services, including Google Keyword Advertising, Search Engine Optimization, Website Design, and social media marketing on Facebook, Instagram, and LinkedIn, helping businesses increase online exposure and business opportunities.

SEO capability analysis

There is no website design service. The official website uses WordPress for SEO, and the website's performance rating is only in the 40s. The case studies are from other web design companies. Both case studies lack an article system, so the techniques are not clear. However, the website's approach is a standard SEO method. There are few case studies to analyze, so it is impossible to confirm many details.

Website performance test results

SEO Case Analysis

Langfeng International Enterprise Co., Ltd. in Taiwan has 3 SEO success stories, similar to Arno Marketing Planning. This number is relatively small. Analyzing these 3 success stories, the monthly traffic is not high, indicating that the website is probably just starting out. The official website itself has written many high-traffic articles, such as "Canva Tutorials" and "FB Posts". Judging from the articles, it is a legitimate SEO practice.

Taichung SEO Company Comparison Table

in conclusion

There are relatively more SEO companies in Taichung that offer website hosting services. Compared to companies in Taipei that specialize in SEO optimization (such as Awoo, Jike Data, and Welly), their service models differ slightly. This difference is actually an advantage for SEO professionals, as website architecture optimization is absolutely crucial for SEO. From a website performance perspective, Da Vinci Digital Technology boasts the best website architecture and performance, with both its own website and client case studies exhibiting excellent structure and loading speed. Companies with average performance include Jiangneng, Weihong, Ailiou, and Chuanliu.
By analyzing the basic information, official website, success stories, and client websites of SEO companies in Taichung, we can deconstruct their architecture, content, links, and SEO traces to understand their practices. However, only half of the companies provide SEO success stories, with Da Vinci SEO being the best, offering 60 successful cases. Because other SEO companies don't provide enough cases, it's difficult to objectively assess their actual effectiveness and ability to drive traffic to clients. The above analysis is for reference only. In reality, it's best to personally inquire about the relevant services of various SEO companies in Taichung for a more accurate assessment.
