Thank you for your answers, that answers my question.

Correct I am wondering if it is any good to add text on images. Vijay, what do you means by "HTML overlay as a direct SEO value", do you mean that google reads it fine ?

For me as long as you can copy the text that is on the image and it isn't embedded is should be ok and google probably reads it fine. However, is the value similar as if it isn't on a image, I have no idea.

Thank you,

Hello,

I am creating an overlay on a image. Is it ok to write on this overlay in html or it is better to have the text not on a image for google and other search engines ?

Thank you,

I totally agree, thank you for your detailed explanation.

Thank you for the information Dr Pete. It is a little more clear. If I understand correctly rank brain is really about user intent in rewriting the query and Hummbird seems to be about voice searches and parsing but it is a little blurry in my mind as you would say other that people at google nobody really understands it fully.

Thank you,

Thank yo. I read it and rank brain is clear hummingbird a little less but I think it is about the knowledge graph and parsing from what I understand.

From my understanding hummingbird is the fact that google is able to parse sentences and link entites to understand the meaning of content in a better way than with just keywords and rankbrain is about user intent, google understands that they are various ways to mean the same thing.

Is my understanding correct ?

Thank you,
