how google rank image?

you can search image in images.google.com, but how google rank a image? page title that image in? or surround text? or alt? or .... which factor is pay more attention by google?

 

Using alt="image description" is the best method to get ranked in Google images.

 

no, i put the alt=keyword. but it not rank well. on #1 page, all have on alt or no keyword in alt.

 

Keywords shouldn't be used, only descriptions of the image. Think of how people use images.google.com to find images and you'll realize how to create your alt.

 

i mean most of image on #1 serp page have NO alt. so which got it #1 page?

 

Many peeps out there have tried this and it works .. Build backlinks for Image URL's as well and if possible wrap some relevant text around it as well.

doing so will eventually push up the image in image results for google. try it

 

I think the file title also helps. For example your targeted keywords is Jennifer Lopez you should named the image as Jennifer_Lopez

 

file name, alt tag, link if any on the image, file name

and you will rank high

 

alt is not a tag, it is an element.

 

alt tag and file title and pagerank of page pciture is on

 

Nope. Not Jennifer_Lopez, but Jennifer-Lopez

 

no it doesnt make difference if - or _ in file name

 

As long as the keywords are inserted in a filename. There's no difference, it helps even a little.

 

Try having keyword next to image, it helps to get ranked on images.google.com

 

yes the content around the image, the page name, and the file name and the alt name all work together in giving relevance

 

hello

u can used this formulla :

alt="image desc.." is the best method to get ranked in Google images.

 

Ssandecki is right.Using ALT tag might boost your ranking. It is also advisable to put your keywords in image file names and image alt attributes. Lastly, make sure your images are worth clicking on. if your images looks horrible, obviously they will not click on it.
