Image Maps
-
Hey forum,
I'm curious about Image Maps. Few things I'm not sure about:
1. Will the links be followed? If so, will Google respect rel="nofollow"?
2. Will the image be considered 1 image? (indexed as image, etc.) Or will each map segment be treated as a separate image?
3. Any other SEO pros\cons to consider when adding an image map to an existing page?
Thanks,
Corwin.

Corwin - that's awesome info - thanks for posting the results of your tests!

For people who find this and want the final results, these are what I see at my site, YMMV:
1. Links from image maps are indeed followed, Google crawls pages that are only accessible via the image map. nofollow also seems to be respected, unless Google just decided not to index these pages for another reason, but I doubt it.
2. The images are indeed indexed for Google images as one image containing the entire map. This image gets the "alt" value of the entire image, not the individual map segments.
I hope this is useful.

Thank you! Great info and suggestions. I'll take your advice and post here once I get the results, so others can benefit from it.

1 - Can't say regarding nofollow - you could always try adding rel="nofollow" to the <area> tag and give it a shot.
Whether the links are followed depends on whether they're indexed. In my opinion, they shouldn't have any issue crawling the links. If you look at the source code of a page with an image map on it (http://en.wikipedia.org/wiki/Image_map for example) you'll see that the links are pretty clearly listed (and in Chrome's source code view they're even hyperlinked - which alone suggests they should be crawling them just fine.)
That said, I have not tested this, and I can't find any references to actual testing done online.
If I were you, I would test this by doing the following:
- Create an image map somewhere on your site (we'll call it the Map Page).
- Link that image map to a 2nd page of the site that is not linked anywhere else on the Map Page.
- Feel free to tweet the URLs of both pages to speed up the indexation process.
- Go in to Google Webmaster Tools, and see if a link is reported to the 2nd Page from the Map Page.
- If there isn't, double check the cache date of the Map Page to see if it's after the image map was added to the page.
- If you go through that test, and GWT doesn't report a link from the Map Page to the 2nd Page, then I would go ahead and use the image map, but I would also add text links on the page to ensure your optimal site structure is in place.
- If GWT does report the link, then that seem sufficient to me, so long as you specify the alt and title text for each individual link since that will function as your anchor text.
2 - The image will probably be considered one image as far as indexing in Google Images (would be strange if they indexed portions of the image), however the alt and title attributes should behave more like multiple images.
3 - I would just do the test I described above and you should be set. Also, take a look at what popular websites using Image Maps do in this situation. National real estate listing sites are a common one for image maps IIRC.

Google Image Search - Is there a way to influence the related icons at the top of the image search results?
Google recently added related icons at the top of the image search results page. Some of the icons may be unrelated to the search. Are there any best practices to influence what is positioned in the related image icons section? Thank you.

Image Audit: Getting a list of *ALL* Images on a Site?
Hello! We are doing an image optimization audit, and are therefore trying to find a way to get a list of all images on a site. Screaming Frog seems like a great place to start (as per this helpful article: https://moz.com/ugc/how-to-perform-an-image-optimization-audit), but unfortunately, it doesn't include images in CSS. 😞 Does the community have any ideas for how we try to otherwise get list of images? Thanks in advance for any tips/advice.

How many images should I use in structured data for a product?
We have a basic printing website that offers business cards. Each type of business card has a few product images. Should we use structured data for all the images, or just the main image? What is your opinion about this? Thanks in advance.

Creating Redirect Maps -To include PDFs or Not to include PDFs?
When creating a redirect map for a site re-build or domain change, it is necessary to include .PDFs or any other non-HTML URLs? Do PDFs even carry "seo juice" over? When switching CMS, does it even matter to include them? Thanks!

What is the point of having images clickable loading to their own page?
Hello, Noticed a lot of sites, usually wordpress (seems to be the default) have the images in their posts clickable that load to their own page, showing just the image, usually a .jpg page. I know these pages seem to be easily indexed into google image search and can drive traffic to those specific pages... My questions are... 1. What is the point of driving traffic to a page that is just the image, there are no links to other pages, no ads, nothing... 2. can you redirect these .jpg pages to the actual post page? I ask because on google image search, there are 3 links to click (website, image link, image page), when you click to view the image, it loads the .jpg page, why not have that .jpg redirect to the real content page that has ads and also has other links. Is this white-hat? 3. Do these pages with just images have any negative effect on optimization since they are just images, no content? 4. Can you monetize these .jpg pages? 5. What is the best practice? I understand there is value in traffic, but what is the point of image traffic if I can't monetize those pages?

Google Not Indexing XML Sitemap Images
Hi Mozzers, We are having an issue with our XML sitemap images not being indexed. The site has over 39,000 pages and 17,500 images submitted in GWT. If you take a look at the attached screenshot, 'GWT Images - Not Indexed', you can see that the majority of the pages are being indexed - but none of the images are. The first thing you should know about the images is that they are hosted on a content delivery network (CDN), rather than on the site itself. However, Google advice suggests hosting on a CDN is fine - see second screenshot, 'Google CDN Advice'. That advice says to either (i) ensure the hosting site is verified in GWT or (ii) submit in robots.txt. As we can't verify the hosting site in GWT, we had opted to submit via robots.txt. There are 3 sitemap indexes: 1) http://www.greenplantswap.co.uk/sitemap_index.xml, 2) http://www.greenplantswap.co.uk/sitemap/plant_genera/listings.xml and 3) http://www.greenplantswap.co.uk/sitemap/plant_genera/plants.xml. Each sitemap index is split up into often hundreds or thousands of smaller XML sitemaps. This is necessary due to the size of the site and how we have decided to pull URLs in. Essentially, if we did it another way, it may have involved some of the sitemaps being massive and thus taking upwards of a minute to load. To give you an idea of what is being submitted to Google in one of the sitemaps, please see view-source:http://www.greenplantswap.co.uk/sitemap/plant_genera/4/listings.xml?page=1. Originally, the images were SSL, so we decided to reverted to non-SSL URLs as that was an easy change. But over a week later, that seems to have had no impact. The image URLs are ugly... but should this prevent them from being indexed? The strange thing is that a very small number of images have been indexed - see http://goo.gl/P8GMn. I don't know if this is an anomaly or whether it suggests no issue with how the images have been set up - thus, there may be another issue. Sorry for the long message but I would be extremely grateful for any insight into this. I have tried to offer as much information as I can, however please do let me know if this is not enough. Thank you for taking the time to read and help. Regards, Mark Oz6HzKO rYD3ICZ

PDFs and images in Sub folder or subdomain?
What would you recommend as best practice? Our ecommerce site has a lot of PDFs supporting the product page. Currently they are kept in a sub domain and so are all images. Would it be better to keep them all in a subfolder? I've read about blogs being hosted on a subfolder to be better than subdomain but what about pdfs and images? thoughts?
