I do not understand much about SEO and website insertion into search engines .
I contain a website, but only use image in it, the maximum text I put in is the phone and address.
- What do you think about this according to SEO and site insertion in Search engines ?
SEO is something delicate that requires time and dedication, it is unfair to say that only images will improve your SEO score since the better your score the better your SEO ranking will be. In the midst of so many criteria to define a site well positioned to use only images would be the same as competing without resources, I recommend using both images and texts.
As already mentioned, SEO is a very broad content so we can get here and pass you a formula
Since you only use images, I recommend that you take advantage of meta tags , fill in as much information as possible so that the search engine can understand your site so that you can recommend it more easily.
Improving the response even more, images usually have this format:
<img src="nome-da-imagem.jpg" width="300" height="150">
The above example would be the basics. In fact, the ideal would be you to use it this way:
<img src="nome-da-imagem.jpg"> width="300" height="150" alt="Nome da Imagem" title="Nome da Imagem" longdesc="Esta imagem é sobre o assunto tal, onde podemos ver que o pôr-do-sol">
With the alt attribute, you tell the search engine what the image is about. Remembering that the name of the same, can not be DSC001.jpg. The src of the image has to be descriptive, indeed.
In this way, it will have an association with the alt and title of the same. Longdesc is like the "article" text, making it easier for people who need some kind of accessibility to use web pages.
If your site is in WordPress, there are several plugins that allow this. One that I point out is WP Accessibility. The advantage of using it is that most of the sites do not use it. So you can easily improve your search engine placement.
But by following other performance rules and social signs so your web page can be in a good position.
