SEO Capability Analysis
As there are no successful case studies, we used website design case studies for testing. The website architecture was good after the test and was at a medium level. However, as there were no cases, we could only evaluate the official website. There were about 30 articles shared, which may have focused more on B2B, so there were no obvious marketing articles.
PSI performance test falls in the middle

SEO Case Study
Weihong Technology Co., Ltd. did not provide any SEO success cases. This may mean that the company has no public cases in SEO services. It is unclear why. For customers who are interested in seeking SEO services, the lack of public cases will increase the difficulty of evaluating its strength and experience. Interested customers are advised to take the initiative to contact them to learn more about their professional capabilities and practical experience.

SEO Capability Analysis
Ouyi Company provides web design, architecture optimization, and link optimization services. Content writing is assisted by AI, but there is no free health check and success case information. The website architecture can only test the official website and customer websites. The official website architecture is low, and the customer's is medium. Because there are no SEO success cases, it is impossible to know too many details. The official website itself has little traffic, so the information is unclear.
PSI performance test score

SEO Case Study
Ouyi Digital Information Co., Ltd. did not provide SEO success cases, which is similar to the situation of Weihong Technology, indicating that the company may not have public cases in the SEO field. For customers who are evaluating SEO services, this is an indicator that needs special attention. In the absence of public cases, it is impossible to effectively verify its SEO practical experience and results. It is recommended that those who are interested in the company need to further understand its core services and technical advantages.

Arnold Marketing's official website does not have much traffic, so its capabilities cannot be seen, but Dongxing Pawnshop is definitely a successful case, and its article output is also very large. Both Arnold and Dongxing Pawnshop are websites built with WordPress, both have SEO plug-ins, and the architecture performance is relatively low. The number of articles on the official website is about 50-60, all of which are regular SEO operations.
PSI performance test score

SEO Case Study
Arnold Marketing Planning Co., Ltd. has 3 SEO success cases, which is relatively small, which may indicate that its experience in the SEO field is unknown. However, despite the small number of success cases, it at least proves that it is capable of completing certain SEO projects.

It also provides website collaboration projects and specializes in the promotion of the German B2B industrial market.
SEO Capability Analysis
Because there are no successful SEO cases, we use official websites and website design cases for testing. The architecture score is low. Because there are no successful cases, we can only observe the official website. There are 20 articles, which are more about the latest news rather than SEO logic. The official website currently does not have much traffic, so it is difficult to judge its SEO capabilities in terms of architecture, content, and links.
Website architecture performance test

SEO Case Study
Oken Information Marketing Co., Ltd. has not disclosed any SEO success cases, and the SEO services on its website do not explain the specific results or experience. When choosing an SEO supplier, if there is a lack of reference cases, customers cannot evaluate their professional capabilities and execution results through past results, and need to spend more time on background investigation and risk assessment. Because it is impossible to further understand their actual SEO operation strategy and results, it is recommended to have a deeper understanding and confirmation with your company before cooperation.

The official website has low traffic and is a one-page website. One-page websites cannot be ranked for SEO because there are no successful SEO cases and there is no reference on the official website. The PSI of one-page websites is not a reference. In addition, without seeing the article, it is impossible to analyze its actual SEO capabilities.
PSI Test Results (One-page website)

SEO Case Study
Chuanliu Information Co., Ltd. does not provide SEO success cases, which is similar to other companies that do not disclose their success cases. This means that their experience in the SEO field may not be disclosed or displayed. When evaluating, customers should take this into consideration and proactively ask about the professional background of their team, service process, and whether there are any undisclosed success cases for reference. Because no cases are provided, we cannot review the effectiveness of these customer cases.

It also provides hosting and regular security scans to ensure that customers' websites operate smoothly and securely.
SEO Capability Analysis
The official website architecture is average, about 60 points. The random test of customer design cases is about 50 points. As there are no successful SEO cases, we can only see the SEO techniques from more than ten articles on the official website, which is considered to be average. Due to the lack of actual case sharing, it is difficult to judge its SEO capabilities.Website performance test results

SEO Case Study
Alio Internet Information Co., Ltd. does not provide any SEO success cases, and lacks actual case sharing in terms of SEO services. For customers who need professional SEO services, there is a high degree of uncertainty in choosing a company that has no public success cases. It is necessary to evaluate the professional capabilities of the SEO company through other means. Without cases, it is impossible to review the effectiveness of the customer's keywords.

There is no website design service. The official website uses WordPress to perform SEO. The official website architecture performance is only in the 40s. The cases are from other web design companies. Both cases also lack an article system, so the techniques cannot be seen. However, judging from the practices of the official website, they are regular SEO methods. There are relatively few cases for analysis, so it is impossible to confirm too many details.
Website performance test results

SEO Case Study
Taiwan Langfeng International Enterprise Co., Ltd. has 3 SEO success cases. Similar to Arnold Marketing Planning, this number is relatively small. Analyzing from the 3 success cases, the monthly traffic is not high. It should be a newly launched website. The official website itself has written many high-traffic articles, such as "canva tutorial" and "FB post". Judging from the articles, it is a regular SEO practice.Taichung SEO Company Comparison Chart
company | Web Design | Website Performance | Architecture Optimization | Article Writing | Link Optimization | Number of successful cases |

in conclusion
There are relatively many SEO companies in Taichung that provide website building services. Compared with companies in Taipei that focus on SEO optimization (such as awoo, Jike Data, Welly, etc.), the service type is slightly different. This situation is actually an advantage for SEO, because the structural optimization of website design is definitely one of the important tasks of SEO. From the perspective of website performance, Da Vinci Digital Technology's website architecture and performance performance are the best. Both its own official website and customer cases have good structure and loading speed. Companies with medium performance include Jiangneng, Weiheng, Ailiou and Chuanliu.From the basic information of Taichung SEO companies, official websites, successful cases, and client websites, we can deconstruct the structure, content, links, and SEO traces to analyze the practices of each company. However, only half of the companies provide SEO success cases. Among them, Da Vinci is the best, providing 60 SEO success cases. Because other SEO companies do not provide enough cases, it is difficult to objectively evaluate the actual results and the ability to bring traffic to customers. The above analysis is for reference only. In fact, it is more accurate to ask about the relevant services of various SEO companies in Taichung in person.
