I have a webpage that has its index.php
page that looks like like Google's home page. I mean it only has a search input box and a logo on it. It is not a Google like search engine but it is a search engine for my database that users can search for something included in my site. I want to keep it like that and I believe it looks simple and good but I'm having difficulty with SEO.
As it has a lack of content, I'm having difficulty with matching meta description and page title to the contents which would increase my ranking. I don't want to use hidden elements to spam inside <h1>
's and words which are going to lead me to be blacklisted on Search Engines.
Is there any advice that would be helpful for me?
<meta>
tag and it is not invisible to users. It is used by the browser in tabs and in the window title. You should call it the "page title" rather than a "meta title". I've edited your question to make that correction.
