Inquiry Regarding Blog Page Rankings

I've been actively monitoring the performance of my blog pages, and I noticed that some of them have not been consistently ranking in the top 3, I aim to achieve a position within the top 3. I did every possible way of SEO to improve their rankings.

I would appreciate it if you could provide insights into the factors influencing these rankings. Your expertise and guidance in understanding how I can optimize my blog content for better visibility would be invaluable.

If there are specific strategies, keywords, or content improvements that you recommend, I am eager to implement them to enhance the ranking of my blog pages.

Java Servlet web development questions

I have been doing web development with PHP for the last few years, and like a lot of people, I have a strong dislike for PHP. I also have done lots of Java development, but never web development. Having a good knowledge of Java, I decided I would try web development using JSP. I have read a few article but I am not fully "understanding" it. My first question is, what is the difference between a JSP (Java Servlet Page) and a servlet? Is a JSP not simply a file that contains a servlet and HTML? My second question is can Servlets interact with HTML elements as easily as PHP? Can I check for HTML form input using POST/GET etc.

I was also wondering if Servlets could use "native" java code. By this, I mean can I use the same code that I use in desktop applications/use the same methods and classes that I have already made. What I am trying to get at is, can servlets do (almost) anything that a desktop application can do. Can I access the server's file system to delete/ modify files? Can I use third part java libraries in my JSP?

If someone could clear this up for me that would be great! Thanks in advance!
