Dynamic image and SEO behavior system

Question

I did a reading on SEO and understood that the higher the text traffic, you have more content to be indexed by Google.

I have an application that is based on images, is practically a "multiple-gallery" generated not exactly like this, but more or less as follows.

foreach(var foto in galeria){
    <img src="~/arquivos/@foto.imagem" />
}

I was thinking, if you create a table that contains a title for the photo and declare in alt or title, my images will have a value for indexing?

foreach(var foto in galeria){
    <img src="~/arquivos/@foto.imagem" title="@foto.titulo"/>
}

In addition, I thought of generating a table in which the user can register TAGs. Example: The application will go beyond this:

<meta name="keywords" content="HTML, CSS, XML, XHTML, JavaScript">

For more or less that:

<meta name="keywords" content="@foreach(var tag in tags){@tag.nome,}">

My content will be treated as text by Google despite being receiving the same dynamically?

Answer 1

Whenever you think about SEO, think about text. If you want to get a closer idea how a search engine views your page use Lynx ( a browser that only reads text). Google says it doesn’t read the meta="Keywords", but apparently Yahoo and Bing attach a certain importance to this meta tag. When to alt attributes, they are mandatory for your page can be validated. Then each image should always have a description that serves as an alternative if the image cannot be displayed. Google reads this attribute and uses it not only to understand your page, but also to display images when searching for images on google.
