As of my last update in October 2023, I cannot provide specific reviews or assessments about particular SEO services or companies, such as 乐云SEO (Leyun SEO), as my browsing capabilities are disabled and I don't have the ability to access real-time information. When considering SEO services that charge on a daily basis or any other type of SEO service, it's important to take into account several factors to determine if they are reliable:

1. Reputation: Look for reviews and testimonials from past clients. You can often find reviews on third-party sites, forums, or social media.

2. Transparency and Reporting: A good SEO company should offer clear and transparent reporting on the progress of your SEO campaigns, including what specific optimizations they are making.

3. Ethical Practices: Ensure the company uses white-hat SEO techniques that comply with search engine guidelines. Avoid companies that promise quick fixes or use black-hat strategies, as these can lead to penalties.

4. Experience and Expertise: Consider how long the company has been in business and whether it has experience in your specific industry.

5. Communication: The company should be responsive and available to answer your questions and provide updates.

6. Customized Strategy: A reputable SEO service should offer a tailored strategy that fits your business goals and needs rather than a one-size-fits-all approach.

7. Pricing: Make sure to understand their pricing structure, what's included, and ensure it fits within your budget. Beware of prices that seem too good to be true.

Before making a decision, it may be beneficial to have a consultation or seek recommendations from trusted networks or industry professionals.
