508 compliance vs good SEO re: Image alt tags
-
I'm currently in debate with our 508 compliance team over the use of alt tags on images. For SEO, it is best practice to use alt tags so that readers can tell what the image represents. However, they are arguing that these images should NOT have alt text as it doesn't add anything to the disability screen reader as the image text would be repetitive with the text on the page. I feel they are taking the "decorative" image concept in 508 compliance too far. It's intention is for images for bullets, etc that truly are decorative in nature and add no benefit to the reader. What is the communities thoughts on this? Have you ever run into scenario where 508 is attempting to ruin SEO? Usually the 2 play nicely.

Even if the image is decorative, it is still describing the contents of the image to visually impaired users. Here's more from Google:
https://support.google.com/webmasters/answer/114016?hl=en
From Google:
"The
alt
attribute is used to describe the contents of an image file. It's important for several reasons:It provides Google with useful information about the subject matter of the image. We use this information to help determine the best image to return for a user's query.
Many people-for example, users with visual impairments, or people using screen readers or who have low-bandwidth connections—may not be able to see images on web pages. Descriptive alt text provides these users with important information."
The image's decorative value is for the user to judge, it's about providing the full story and experience to all users not some.

Hi Rose,
Hopefully Donna answered your question already, but I want to jump in with some SEO prioritization advice.
Alt text like this can add to the relevance of the page, but minimally. It can also help your image rank correctly in image search, but that doesn't bring much traffic now that Google pulls images into its results page.
I had similar conversations with our compliance team when I worked for a university, and they had a similar perspective, that alt text should be determined by the flow of the reader rather than for small SEO boosts. The nice thing is, though, when images are important to the flow of the page, and are more likely for the alt text to support the keywords you're trying to target on a page.
In short: if I were you, I'd let this argument go, and just push for alt text on images that tell a story. There's no SEO penalty for not using alt text, and I doubt you're worried about ranking for "father and young son."
Best,
Kristina

I'm with you Rose. The alt tag describes the image. If you want it to include your your keywords, assuming they're some combination of "Child Support Noncustodial Parent Employment Demonstration" (your page title tag content), you could alter it to say "noncustodial parent with his young son". You could do the same with the file name, include "noncustodial-parent-son".
Here are google's guidelines, as conveyed by Matt Cutts, head of Google's Web spam team and defacto SEO spokesperson.

I'll provide an example. http://www.mathematica-mpr.com/our-publications-and-findings/projects/child-support-noncustodial-parent-employment-demonstration
On the page linked above, there is a medium size image depicting a father and son. The alt text there is "father with young son", the compliance team is arguing that the alt text should be removed as it adds no value. My thought was around changing the alt text to be more specific to the article, but even how it currently is it tells the screen reader that the image is of a father with his young son which is accurate. The compliance team feels these are decorative images - and I can't disagree more. I was hoping to find some evidence to support my case.

I must be thick because I certainly don't understand the statement "they are arguing that these images should NOT have alt text as it doesn't add anything to the disability screen reader as the image text would be repetitive with the text on the page. "
No, I haven't run into this problem before. Perhaps they're referring to situations where alt tags just get stuffed with keywords. Image alt tags shouldn't just repeat the text on the page or act as a repository for keywords, although that's often what you see. Image alt tags should accurately describe the image first, use keywords second and where it makes sense.
So, for example, this page has an alt tag coded for the little blue button above that depicts Roger, the company mascot (<img <span class="html-tag">alt</img <span>="Roger_blue_square"). The text "Roger blue square" doesn't appear anywhere else on the page. (Well I guess it does now!) It's a bit succinct - first time visitors might have a heard time understanding what the image represents - but it is accurate and isn't just stuffed with "Moz Q&A Community" keywords.
I'm waiting for the day when Google decides to start penalizing folks for doing what you've described above.

Best Permalinks for SEO - Custom structure vs Postname
Good Morning Moz peeps, I am new to this but intending on starting off right! I have heard a wealth of advice that the "post name" permalink structure is the best one to go with however... i am wondering about a "custom structure" combing the "post name" following the below example structure: Www.professionalwarrior.com/bodybuilding/%postname/ Where "professional" and "bodybuilding" is my focus/theme/keywords of my blog that i want ranked. Thanks a mill, RO

Top hierarchy pages vs footer links vs header links
Hi All, We want to change some of the linking structure on our website. I think we are repeating some non-important pages at footer menu. So I want to move them as second hierarchy level pages and bring some important pages at footer menu. But I have confusion which pages will get more influence: Top menu or bottom menu or normal pages? What is the best place to link non-important pages; so the link juice will not get diluted by passing through these. And what is the right place for "keyword-pages" which must influence our rankings for such keywords? Again one thing to notice here is we cannot highlight pages which are created in keyword perspective in top menu. Thanks

Heading Tags (Specifically H2) being used within images
Hello, Mozzers I have a question regarding placement of heading tags. I have seen this asked a few times on the forum but some are from a couple years ago so wanted to get a more up to date answer regarding this. We want to add H2 tags across our site but our two options are to wrap images we are using as navigation on the top of the page, these are directly below our pages H1 tag and actually make sense. Example H1 title: Vehicles Images are specific brand logo with H2 being wrapped to pull the img alt: "Ford Vehicles" "Checvy vehicles" etc. The wrap would look something like this: I appreciate your time, Chris

Canonical tag + HREFLANG vs NOINDEX: Redundant?
Hi, We launched our new site back in Sept 2013 and to control indexation and traffic, etc we only allowed the search engines to index single dimension pages such as just category, brand or collection but never both like category + brand, brand + collection or collection + catergory We are now opening indexing to double faceted page like category + brand and the new tag structure would be: For any other facet we're including a "noindex, follow" meta tag. 1. My question is if we're including a "noindex, follow" tag to select pages do we need to include a canonical or hreflang tag afterall? Should we include it either way for when we want to remove the "noindex"? 2. Is the x-default redundant? Thanks for any input. Cheers WMCA

Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)
Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
Intermediate & Advanced SEO | | browndoginteractive
2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality: http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results: Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index: robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages. I say "force" because of the crawl budget required. Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links. Best of both worlds: crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution: using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.0 -
How to See Image Metadata?
We sell 1000s of audiobooks and get our cover images and descriptions from the publisher’s sites. When I download a cover image such as this one (http://www.audiobooksonline.com/media/Alex-Cross-Run-James-Patterson.jpg)
Intermediate & Advanced SEO | | lbohen
I always rename and re-size it before installing at our Web store. Would this process result in any publisher’s metadata in the image we use at our Web store and/or anything else Google would not like?
Is there an online utility that would allow me to see metadata in our images?0 -

Does capitalization matter for SEO?
Two places capitalization comes into play: (1) on-page use (title, h1, body text, img alt text, etc) (2) external anchor text I didn't think it mattered from Google's point of view for on-page usage (is this correct?) but I notice that OpenSiteExplorer' s 'anchor text distribution' tab shows different counts for the same keyword if it's capitalized in different ways (eg seomoz.org is listed separate from SEOmoz.org). Is that just OSE or does Google treat the keyword/phrase different based on its capitalization, too? And if so, then should I be creating external links to my site with the 'regular' and 'Capitalized' versions of my key phrases?
