Do images on a CDN affect my Google Ranking?
-
I have recently switched my images to a CDN (MaxCDN) and all of the images within my post are now get loaded directly from the CDN.
Will this affect my Google ranking? Do Google care if the image is hosted physicaly on the domain?
-
Thanks Robert for the detailed answer. Very helpful!

Amosnet,
Where the image resides as a static file does not matter. Whether served by the CDN or your site, any image still needs to have good alt text associated with it (describe the image as opposed to 33 keywords). The CDN will probably offer some benefit (especially if you have a lot of JS or images, etc.) as it should increase page load speed. I do not know how much value is allotted, but I do know once you start going over about 5 sec. it begins to affect adwords. We try to keep all or ours to about 2 to 3 sec. max.

H1 text and Header Image Overlap?
I have images with text at the top of every page on my site. But no H1 or H tags at all. I would like the text on the image to be my H1 text. But I don't want to be repetitive. What should I do?

How does Google handle read more tags in Wordpress
Hi Everyone I am wondering how Google handles the read more tag in Wordpress. I pasted the link to a blog post on Google and found nothing (domain.com/post#readmore). Then I paste the version without #readmore (domain.com/post) and found that Google indexed the page but with the option to click "read more" to read it. The full blog post is not in their index, just the version asking you to read more. Is this because Google hasn't gotten to it or is Google ignoring it. I am not sure but ideally I rather have the full blog post indexed, not the read more version. I am curious to whether this will cause duplicate content issues. What are your experience with this and is it advisable to use an alternate method for read more. Maybe with a Wordpress plugin. Thanks in advance.

NOINDEX, FOLLOW on product page - how about images indexing?
Hi, Since we have a lot of similar products with duplicate descriptions, I decided to NOINDEX, FOLLOW most of these different variants which have duplicate content. However, I guess it would be useful in marketing terms if Google image search still listed the images of the products in image search. How does the image search of Google actually work - does it read the NOINDEX on the product page and therefore skip the image also or is the image search completely dependent on the ALT tag of any image found on our site? Thanks!

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!

Does CTR Affect Ranking & Authority? Can PPC Influence That Too?
Hi everyone, Good CTR and bounce rate seem to affect rankings positively, but what about domain authority? Is that something built entirely on links and semantics, or does CTR play a factor too? Consider a homepage ranking for its brand name. Switching off any brand PPC will increase the natural listing's CTR. Would that have a positive SEO impact on the homepage/domain?

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!

Image file name, is it important
If I use the same image all over my site, do I need to change the file name to avoid duplicate? Different alt text will be use on those images
