Why SEO is not suitable for using a free agent?

In the process of SEO optimization, establishing a large number of backlinks is an important strategy to improve the search engine ranking of a website. Using proxies for link building can quickly increase the authority of your site and avoid being restricted. However, is it possible to use a free agent for SEO optimization? Here are three reasons why SEO is not a good place to use a free agent.

1, lack of security: In the working principle of the proxy, the proxy server acts as an intermediary between the user and the target website, hiding the user's real IP address, so as to achieve anonymous access. This anonymity is essential to protect the identity and privacy of users, especially during the transmission of sensitive data and private information. However, free agents often do not provide adequate security, so there is a risk of information leakage.

Providers of free proxies often do not have the funds and resources to ensure the security of their proxy servers. This means that these free agents may lack the necessary encryption and security measures, leaving them vulnerable to hackers and malicious attacks. If the proxy server is breached, the user's identity information and privacy may be leaked, resulting in serious consequences.

In addition, some free agents may record the user's visit data and activities, including websites visited, form data entered, and so on. These records may be used for commercial purposes, such as AD targeting or data sales, thereby violating users' privacy rights.

In contrast, paid agents typically provide a higher level of security. Paid proxy service providers typically devote more resources to maintaining and protecting their proxy servers, adopting stricter security measures to ensure users' privacy and data security. Some paid agents also provide end-to-end encrypted communication, ensuring that user data is effectively protected during transmission, preventing man-in-the-middle attacks and data breaches.

2, unstable speed: Because the free proxy is usually used by a large number of users at the same time, the bandwidth and resources of the proxy server may be limited, resulting in unstable connection speed. When doing SEO optimization, it is very common to send requests and get data frequently, which requires that the speed of the agent must be fast and stable enough to ensure that the task can be completed efficiently. However, unstable agent speeds can lead to task delays and unreliability, affecting the optimization work. When using an unstable free agent, the following issues can occur:

Frequent connection interruptions: Due to heavy load on the proxy server, connection interruptions may be common. This means that in the process of sending a request or obtaining data, the connection may be suddenly interrupted, resulting in a failed request or incomplete data acquisition, which affects the effect of SEO optimization.

High latency: Erratic agent speeds typically result in higher latency and longer times for requests and responses. When it comes to SEO optimization, time is often of the essence, and high latency can make the execution time of tasks significantly longer, thus reducing work efficiency.

Inaccurate data: When doing SEO optimization, it is necessary to obtain accurate data to analyze and optimize the website. However, unstable proxy speeds can lead to incomplete data acquisition or errors, which can affect the accuracy of the data and the reliability of the analysis results.

In contrast, paid agents generally offer more stable and efficient speeds. Since the paid proxy is usually used by a small number of users, the proxy server has a smaller load, and the bandwidth and resource allocation are more reasonable, thus ensuring a more stable connection speed. This makes it possible to send requests and obtain data more quickly when performing SEO optimization, improving work efficiency and the accuracy of optimization results.

3. Easy to block: Free agents are vulnerable to abuse because so many users use them. This can result in proxy IP being frequently blocked from websites, which can affect your SEO efforts. After being banned, you will no longer be able to use the agent for link building, thus losing valuable SEO time.

In contrast, paid agents offer higher security and stability. Even if your proxy IP is blocked, you can easily get a brand new IP address from the proxy service provider and continue your SEO work. Therefore, for SEO optimization that requires efficient completion of the business, paid agents are a wiser choice.
