Can lazy loading of images affect indexing?
-
I am trying to diagnose a massive drop in Google rankings for my website and noticed that the date of the ranking and traffic drop coincides with Google suddenly only indexing about 10% of my images, whereas previously it was indexing about 95% of them.
Wondering if addition of lazy load script to images (so they don't load from the server until visible in the browser) could cause this index blocking?
-
Although Google can now get to js, I would still be nervous on choosing a theme/CMS that is using lazy loading.
According to John Muller from Google:
“Is Googlebot able to trigger lazy loading scripts- lazy loading images for below the fold content” – “This is a tricky thing.”
On lazy loading images John says “test this with Fetch as Google in Webmaster Tools” and “imagine those are things that Googlebot might miss out on.”

Option to index images? Or option to index image attachment pages? I've not seen the first, but I have de-indexed attachment pages because I didn't have time to make them all unique. Where do I find the option to not index images? And why would that make SEO scores better?
-
Yes - could be. You need to use Google SearchConsole Fetch&Render tool to identify are images is loaded at all.
Also note that some of lazy loading tools used data-src ( https://github.com/dinbror/blazy ), other pagespeed_lazy_src ( https://developers.google.com/speed/pagespeed/module/filter-lazyload-images?hl=en ) and third data-img-src and many others. You need to check what attribute your tool is used and check are images crawlable and indexed.
You need to check also Qazy - https://github.com/qnimate/Qazy yet-another-lazy-loading tool without negative SEO impact because images are loading from src attribute. And this is explained here: http://qnimate.com/lazy-loading-images-and-its-seo-impact/
So - yes this negative impact could be caused from images lazy loading too.

Hi!
Big images reduce the speed on the page and speed is a(n increasingly important) ranking factor. You could use Page Speed Insights to see your overall site speed or the speed of a specific page.
Within Worpress there is also a setting to index images as a search result or not. On my site it was on and once turned off within a few weeks my overall scores increased so maybe that helps aswell.
Good luck!

Does Google avoid indexing pages that include registered trademark signs?
I am suspecting that Google often hesitates to index pages that have registered trademarks on them that are marked with a ®. For example EGOL® used in the title tag or in the tag at the top of the page. Registered trademarks are everywhere and most retail product pages contain at least one of them. However, most people use the registered trademark names as text in their writing without adding the registered trademark sign of ®. Have you experienced a problem getting such pages indexed or have you read any articles about how Google treats registered trademarks?

Google is indexing urls with parameters despite canonical
Hello Moz, Google is indexing lots of urls despite the canonical in my site. Those urls are linked all over the site with parameters like ?, and looks like Google is indexing them despite de canonical. Is Google deciding to index those urls because they are linked all over the site? The canonical tag is well implemented.

Fading in content above the fold on window load
Hi, We'd like to render a font stack from Typekit and paint a large cover image above the fold of our homepage after document completion. Since asynchronously loading anything generally looks choppy, we fade in the affected elements when it's done. Sure, it gives a much smoother feeling and fast load times, but I have a concern about SEO. While Typekit loads, h1, h2 and the page's leading paragraph are sent down the wire with an invisible style (but still technically exist as static html). Even though they appear to a user only milliseconds later, I'm concerned that a search engine's initial request is met with a page whose best descriptive assets are marked as invisible. Both UX and SEO have high value to our business model, so we're asking for some perspective to make the right kind of trade off. Our site has a high domain authority compared to our competition, and sales keyword competition is high. Will this UX improvement damage our On-Page SEO? If so and purely from an SEO perspective, roughly how serious will the impact be? We're eager to hear any advice or comments on this. Thanks a lot.

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?
