Alt Tag for Mobile/Tablet
-
I have device optimized images for desktop, tablet, and mobile. Should I put the same description, caption and alt tag for each? Not sure if this will hurt me or help?

Hi, as long as your website is properly optimized for mobile SEO (for instance, if you use dynamic serving for the images, make sure you include the Vary-HTTP header to let Google know that you're doing that) using the same descriptions etc across all versions shouldn't cause any issues. You can also feel free to optimize each version differently if you discover (for example) that users use different search terms when searching for images on a mobile device versus a desktop.
Bear in mind these are images, so you'll want to optimize for the image content, not the target keyword of the page that the image appears on.
Hope this helps!

Alt Text Best Practices
I am working on alt texts for my WordPress website. I've done a bit of research and read best practices, but I am a bit confused on how to write some of the alt texts because my entire site includes images. I know this is a big no-no and I am working with my team to get the site SEO-optimized (better text to image ratio). However, in the meantime, I need to make sure that I have some alt texts for my images. Can someone help with the following questions: 1.) I have the same "close" button in 4 locations. Can I use "close" as the alt text four times? Or should I explain where the close button is or what it closes? 2.) If my image is only text and it is more than 125 characters, is this a problem? Should I use longdesc=? If so, how do I input that in a WP site? 3.) If I have my logo in 3 locations, should I differentiate the alt text? 4.) If I have FB icon, do I just state Facebook and don't say icon? 5.) I have some background images and they don't really provide relevancy to my site other than aesthetics so should I not have alt attribute? If so, do I just place alt="" in the alt text field or does it have to be in the code? 6.) In WordPress, do I remove the description under “title,” and just put a description under “alt-text?” 7.) Can I repeat alt texts? For example, I have 4 buy now buttons, should the alt text be “buy now” all 4 times or be specific to what they are buying, such as “Buy now – Teatopia Dream On supplement drink?” 8.) I have 4 nutrition label images so can I just state what each label refers to or is it expected to have a long description with all the text on the label? 9.) I have images for desktop vs. mobile. Can I have similar copy for both. The mobile page is not set-up to index so do I even need alt text for the mobile images? 10.) Can I have characters, such as dashes and commas, in the alt text? Does initial cap matter? 11.) For decorative images or when an alt-text is not needed, do I just place alt=”” in the alt text field in WordPress?

Adding logo to graphics/memes/etc?
Do you all think it is best to add your logo/brand (in some small way) to graphics/meme/ etc that you create? I understand that the most important part about creating said content is that it is of high quality and usefulness to our audience, however, after something of that caliber has been created, have any of you noticed any difference by adding or not adding your logo/brand? Any suggestions, stories, resources, etc are always appreciate. Thanks in advance for your time and input, Ruben

Google Places / Map Results CTR vs Top Organic Result
I have a client who is currently ranking close to the top of the Google Places results for a handful of important local keywords. They have a competitor who is pretty consistantly ranking in number #1 and #2 organic positions, above the Places results. Does anyone know the average click through rates for results similar to these? Do the #1 and #2 organic positions still outperform the lower placed Google Places (with side map) results when the search intent is very local? I just wonder if they are possibly in a better position as-is if people are more likely to use the map or places listings on the SERPs page, rather than click through to another site. Thanks 🙂

SEO for Explicit / Medical Pictures - Will It Hurt Rankings?
I have a client with page 1 rankings for several keywords. He wants to make some updates to his website. He is offering a new service and wants to show before and after photos of the procedure. He is an OB/GYN, so the before/after pictures are very explicit and have full nudity. How will this affect his rankings? Is there something that I can do to tell Google and other SE's that these photos are medical and not pornographic? Should I host them on another domain? Just looking for thoughts and insight. Thank you in advance!
