I intend to do a website, the most important part is to develop it.Thanks to you to advise and assist.
Yes, of course the content is important; People visit websites for their content.
I don't understand your question.
What did you intend for your website to be about?
Maybe you need a web developer? You can hire one that could develop and maintain it. I could recommend you some people I know. Just let me know if you want them.
Generic questions like this really serve no purpose here. If you want an idea of how important content is to a web presence, do a search through this forum or search on your favorite search engine. There are thousands, perhaps millions, of articles on the importance of good web content. After you are better grounded, if you have specific content questions post them in a new thread. For now, this thread is closed.
