The structure of web pages, is a very significant part of website designing. Most of the people surfing the net like consistency. This applies to the structure of your web pages as well. So, even if you are bored of the same structure, stick to it. Do not try to experiment and create different structures of different web pages. This might end up confusing the visitor and thereby forcing him/her to exit.
Automatic pop-ups can be a real nuisance for net surfers.
If you are toying with the idea of whether or not to include some in your website, then don’t!
Pop-ups are typically used when you want to display some unimportant information. Most visitors know this fact and thus do not like automatic pop-ups. If there is any information that you would like to incorporate as automatic pop-up, then integrate it in your website. However, this should be done in an interesting way to grab the attention of your readers instead of shooing them away by having pop-ups.
