Image format for SEO

[David123]

want to know which Image format best for SEO?

Google doesn't care about the image format, it depends what format is better for your image in terms of compression, size & quality.
Just try to follow these best practices:
properly compress to reduce size & page load as much as possible, serve scaled images on your mobile version, use proper alt text, use image sprites where needed and suitable.

Yeah, MegaFreeChips is right, also give unique and related name to your images. Like "prague-online-casino-2015"

I use .jpeg most of the time due to the fact that it is smaller in size, making my pages load much faster, which google and my visitors like, as MegaFreeChips said, it doesn't really matter what format you use. Use appropriate structure to your alt text though, don't make it spammy, have it related to the content. Short captions when warranted are not a bad idea either. Don't use generic images though, as I have seen plenty of sites use the same photobucket images and it just doesn't engage.

.svg is scaleable format, however it does not matter, in terms of page speed, optimize your images in size, use proper compression on your server. Page speed can be increase with .htaccess code also, add this code in .htaccess and compare load speed before and after
