Background Images and ALT text
-
We pretty much exclusively use background images for our sites. How do I add in alt text? I tried a Google search for this issue and the best answer I could find was "Use the 'title' tag in the containing div", but that was from 2010.
Is there a better way to do it? And no, we're not going to switch to using standard images, because background images are way more slick for UX.

Does it has any positive effect on ranking? (seo)

You can't use ALT text to background images.
If your images are loaded as img tag then you have title, alt. Example:
But background images isn't regular images loaded with img tag. They can be loaded only with CSS styling. And therefore they doesn't comes with title and alt. Example:
As you can see you can't use title or alt for image there. Only way is to define title as this:
or better this one:
I know that isn't 100% background but also helps.Alternative way can be ARIA. If you love background images but really wish alt text you can use WAI-ARIA and define them as:
...
But GoogleBot doesn't support aria-label for now. -
Yes for screen readers and using it as alt and title for your images that are there. So you are not trying to trick Google, you are trying to figure out a way to mark what is actually there. For google image search, I have had success ranking images even if used as backgrounds in divs by naming them with what I was trying to rank them for. Since I could not use alt or title I named images with my target in them. These images were all for a brand query.
Example: image on mybrand.com named mybrand-imageName.png
we were able to get most of those images to show up when doing an image search for mybrand

I'm going with "Google is too smart for that" on the transparent image alt text front. I guess it would help out people using a screen reader, but I'd like to get some of the images into Google image search. It seems like alt text is pretty much required to rank for that?
-
I think that adding title to the div is the only way for you to do a background image in CSS.
You can cheat a little by then loading a transparent image in the container that the background image is in, make this transparent image have an alt tag and title tag for whatever your background image is about.
If you are doing this for seo purposes this should work, if you are doing it to have the html well formatted, there is only the div tag.
Cheers!

Multiple H1s and Header Tags in Hero/Banner Images
I work on education websites, and our sites are being flagged by SEO and accessibility checkers for having multiple H1s. The home pages have the site name as an h3 in the hero image, and an aspirational headline (think: Be Like Mike) as an H1. The sub-pages have two H1s: one on the site name in the banner image, and the other on the page title. Note that the site name is very keyword-rich. If we were to remove the H1 and H3 tags from the hero/banner images, would it do any SEO harm? At the same time, we’d rewrite the H1 on the home page to be more keyword-focused. Any other options? I also read that it’s OK to have multiple H1s as long as it’s clear which H1 belongs to the heading area and which one belongs to the body area of the page. Thanks in advance!

Is using a H1 tag in a logo image bad for SEO?
We have brand logos on certain pages that have H1 tags in them - the H1 text being the brand's name, as this is what we'd want the title of the page to be. The logos are at the top of the page instead of a written title. But is this the best option for SEO? Do search engines value H1 tags in images as highly as a standard H1 tag?Would it be better for SEO to add an alt tag to the logo and add a separate H1 tag on the page that's also the name of the brand?

Clickable Images Question
This may seem like a minor issue but it is something that has been bothering me. When I write a blog post and place images within the text, is it better to have the image linking to nothing or link to the image url. I am guessing that unless I wish the image to rank for a certain keyword then it is not worth it linking to the image url. But would just like clarification if there is a more deep seated reason. Thanks Mark

Alt text / internal linking
Hi everyone A question about best practice when linking from pictures on our homepage - hirespace.com We have an option of using divs with background images (nicer in terms of design) but it means that we can't use anchor text or alt text to show Google what these internal links are about. The other option is to use images which do not allow us as much flexibility in terms of CSS but would allow us to use alt text. There is also an opinion that we should have separate text links at the bottom of the homepage to get the anchor page in. What is best practice in this situation - is alt text worth sacrificing some CSS flexibility for? How important is anchor/alt text for internal linking? Thanks guys.

Image naming best practices?
While I have found many good sources of information for naming images for SEO purposes, I'm having trouble finding an up-to-date, exhaustive and authoritative source for image names, alt tags, etc. For instance... Max characters for image name? Max hyphens? How descriptive should you be? "ice-cream-flavors-icon_._jpg" or "ice-cream-flavors.jpg" or simply "ice-cream.jpg" How similar should the image name, alt text and page title be? At what point are you overusing a keyword? Rules to follow? So much more, but you get the idea! Anyone have a good reference or an answer to all things related to images and SEO? Thanks!

Should I use bold for the first few sentences of a text?
I would like to know if anyone knew if the relevance of a page changes if I bold the first few sentences. Our journalist wants to bold the first few sentences in every article to make it easier to read, how does that affect SEO?

Image Optimization - File Name Important?
I am currently working on a site with 100+ recipes that all have image file names that are relevant, but not optimized for keyword purposes. I'm wondering - from an SEO perspective - would it be worth my time to go back through all of the images and rename them with keywords in mind? On my own site I have always done this as a "best practice" but I'm curious - does it make a difference to search engines? Does anyone have any recent research/experiences that they would like to share? Thanks!
