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?
