I have created a technical article blog page for my friends, and since 2019, I have published a total of 150 articles and continue to add more. However, the daily traffic fluctuates between 30-60 visits. I have purchased SEO packages from forums a few times, but my traffic did not increase. I strive to write original articles as much as possible, with 95% of my content being original. After researching forums, I found that some bloggers are able to achieve 2k daily visits with just 20 articles. How are they able to do this?
