Alt-text on all my images or only my contextual images?
-
Hello everybody,
I have a question regarding Alt-text. Is it important, regarding SEO, that I add alt-text to all my images, or only on my contextual images?
Hope someone can help me.

I wouldn't add ALT tags to all images. Only those that add context to a page - if it's a design element that repeats from page to page it would be incredibly annoying to have it read out by a screen reader over and over again. Example: 'Company X Logo, Company X Logo, Company X Logo, Company X Logo....' How to wind-up the blind very quickly!!!
I started my digital career working for an agency that specialised in producing accessible websites for schools, nurseries, public libraries etc. I learned a lot about how screen readers work there and it was a real eye-opener. (if you excuse the pun)

Hi,
I would add alt text to all images. As Amelia mentioned, if helps users that are using a screen reader or if the image doesn't render, it gives visitors an idea what the image is. Furthermore, since Google can't crawl image yet, it tells Google what the image is about.
In addition, it also helps with your Google Image ranking which can lead more visitors to your site when they are searching for an image on Google.

This is a really good question.
I think ALT tags should be used on all images that add information to the user, but not on those that are just there to add a bit of interest to the page (background images etc).
Someone using a screen reader would find it intensely annoying if you just stuff keywords into your alt tags. Don't ever forget the true purpose of alt tags: they are there to help people using screen readers (generally blind and visually impaired people) to 'view' a web page. Not to get additional SEO benefit. Though of course, if you choose relevant images you can 'kill two birds with one stone'!

I wouldn't bother with design element only images; borders, backgrounds etc... only actual images of something you can describe. I would also stay very far away from just adding keywords to the alt attribute. If the images are relevant to the page's focus just describing the image accurately will help a great deal.

The alt image is great for helping visually impaired users and seo engines its a good idea if you've got the time to give all your images alts.

How much can our page title, URL and alt-tag differ without negatively affecting SEO?
We are a bridal store selling wedding dresses and bridesmaids dresses. We are wanting to know how much our URL and page title can differ, whilst still optimising SEO. For example, for the category Wedding Dresses, the URL contains wedding dresses, so can we use " the best wedding dresses in Sydney" in the page title? For the bridesmaid dresses (URL is /bridesmaiddresses/) can we use " buy best bridesmaid dresses online in Australia"? Can we use terms such as "buy best black dress in sydney", "buy online in australia" or "shop online in sydney" in the alt-tag, additional from the page title .i.e. adding extra keywords in the alt-tag that do not appear in the title? Would this be classified as keyword stuffing? In our main categories .e.g. Wedding Dresses, can we add "best wedding dress store", "buy wedding dresses from best wedding store in sydney" in the alt-tag? Thank you.

Https lock broken possibly due to absolute http header footer image links.
To make the https lock secure, can I make my website header and footer image URLs to relative? I have read that we need to have absolute URLs for images for good SEO. In our old ecommerce platform we made http image urls for http pages and https image urls for https pages. For our new platform this is not a standard feature and we will have to pay for customizations which we don't have any more budget for that. So will making image URLs relative create any other problems?

Optimizing Images
I have realized that our images are way to big. I would like to resize them and upload back again but I am afraid to do it as every image in wordpress is uploaded and has own link and then all this links will be not found. Is there some other way how to do it without a plugin. Or it is not a problem that I will delete that old large images and then upload the new smaller? Thank you very much for any advice Iris

Google Knowledge Graph - change bio image
I have a client who is a well known personality in a particular niche that I've done some general event and design work for, but he hasn't had interest in SEO or social help until this point. He is very displeased by the image that was chosen for his Google Knowledge Graph result when you search his name. The issue isn't due to a poor photo, but rather due to the site it links through to. Google has chosen to use a bio image for his Knowledge Graph result which links to an "anti-" site. This site is opposed to the organization he leads. If you click on the image, it sends you to an image result page backed by an article which is full of misinformation and overall negativity about this individual. The source is also listed under the image on the Knowledge Graph result, a source he doesn't believe deserves any publicity, especially in conjunction with his name. So, what best practices might you suggest should be employed to go about getting Google to choose a replacement image for his Knowledge Base bio? Optimize his own bio page and bio image on his website? Get an image on his Wikipedia page? Create a G+ page with the bio image? Integrate the rel author syntax into his articles pointing back to his bio page? He doesn't want this to become a public matter, so he's against posting the issue to Google's Help Boards or reporting it in a public fashion. I'm not sure what should be the best first steps and top priorities for him and am hoping the SEOmoz team is starting to see some trends with Knowledge Graph. Let me know your thoughts when you can. Thanks so much! iLqNW iLqNW.png

Google Images in Normal Search
If you search for the term, "Crappie". Listed 4th is a row of images. These kinds of images always seem to grab my attention above the actual search results-- or at least they do for a moment. These images seem to be in order of google images rankings. I may try to take a swing at ranking for these images. Is there anything else I should know before I start? I can't seem to find any guidance on the topic. Thanks

How do you bounce back from a loss in image search?
Looking for any help in understanding what I can do to get my images back up in the images index. My site took a hit last month which I've been working to get back up but nothing has seemed to push the needle. Has anyone else experienced such a loss in the image index before? kVTuL.png
