Search engines don’t see your website the way people do. Search engines read your website and try to match the words in it with what they think your website is about. This means that if a person searches for something and can’t find it, or if they can’t make sense of what they are reading, they will leave and probably never come back to your website. But that doesn’t have to happen. If you use proper search engine optimization, you can make sure that when people type in a search word or a search phrase into a search engine, your website shows up at the top of the results and is easily readable and navigable.
Also, make your titles and meta-tags clear about the connection your users should be able to see between the words and the pictures on your site and the words and phrases in your title and meta-tags. The connections should be obvious. Don't make your users work too hard to find what you want them to see.
Another thing to remember is that search engines do not see graphics, thus every image on your site should have an alt tag that describes the image so that both search engines and people who are visually impaired will be able to see the graphic you are attempting to display.
