Alt Tags on multiple product images
-
Hi
I work on SEO for an ecommerce site and wanted to find out how important it is to optimise all images with alt tags.
We have alt tags in place, however have not optimised descriptions for the following example images:
Front of cupboard
Back of cupboard
Side of cupboard etc
Is this dangerous for SEO if these images all have the same alt tag?
We have thousands of products so it would be a huge job to update these, but if it's crucial for SEO we can work through our priorities.
Thank you!

Yes I was thinking of testing this.
I have just checked our images and from what I can see the devs have set the alt tag to default to the product title.
Then the image title is a bit more descriptive - does the image title/legend help with anything or should we ignore these and update alt tags instead?
-
Sorry Becky, I forgot to say that without some level of testing, it is almost impossible to say with any degree of certainty just what you would get from this as a site-wide task. Depending on the products, searches conducted and how Google ranks the images, you may find a good deal of additional traffic or you may find very little.
Perhaps take a control group to test and monitor the products over the course of a month to see if sales / traffic has increased.

Do you still not need to optimise each different image?

Thank you this is really helpful!

Great thank you very much for your help!

Hi Becky,
You aren't likely to be penalised for this, but the benefit you can derive from ALT text will be lessened. If the picture is of a floor fan, and the ALT tag says this, there is no problem.
However, I would be saying something like "Metal Blizzard Floor Fan 12" 55W with tilt". It will help because you have more of a chance of it turning up in image searches = more traffic.

Definitely a great idea is there is a dev on hand to do this

Hi Becky,
Completely agreed with Andy's suggestion.I would like to add one more thing here I'm also working on a large e-commerce site with thousands of products. I find a good way to insert alt tag very easily I asked web developer to create a module by which every products having alt tag with product name and web developer did a great job by writing only few lines of code. you can ask web developer to do the same.
Now I don't need to add alt tag individually on each product and it saves my time.
Hope this helps.
Thanks

Hi Andy
That's great thank you. I'm finding it harder to describe some products, which have very similar images. Say for instance, a fan at different angles.
Will I get penalised if Alt tags have the same name? So if say 3 images all have, floor fan? This is happening as a default at the moment, but I am looking into getting them updated - however if the benefit is small other tasks will be prioritised.
Thank you

Hi Becky,
What you need to be careful of, is over optimising with ALT tags. This can lead to issues, but what you suggest is correct. John Mueller from Google had this to say about ALT tags...
"alt attribute should be used to describe the image. So if you have an image of a big blue pineapple chair you should use the alt tag that best describes it, which is alt=”big blue pineapple chair.”** title attribute** should be used when the image is a hyperlink to a specific page. The title attribute should contain information about what will happen when you click on the image. For example, if the image will get larger, it should read something like, title=”View a larger version of the big blue pineapple chair image.”
If the image someone can click on is the rear view of a cupboard, then say this in the ALT tag. However, it is worthwhile remembering that you need to be descriptive with these.
Here is a great article on the subject.

H1 tag positioning impact
Hello, I am currently working with a dev team to develop a new site. We have designed the title tags to sit below a banner image on each page but the technical team are insisting the h1 title tags must come above the banner for maximum SEO impact. I am sceptical about this, can anybody please shed some light and/or share any up to date resource on this? I have attached a side by side wireframe to illustrate the pages with the h1 tags in both positions. Thank you! HnWcLTx

Product Descriptions (SEO)
So I would like a few opinions. How long should a product description be? Enough to get the point across? 100 words? 800 words? Over detailed? Any advice would be appreciated.

Tags - Good or bad for SEO
We are getting Moz errors for duplicate content because tag pages share the same blog posts. Is there any way to fix this? Are these errors bad for SEO, or can I simply disregard these and ignore them? We are also getting Moz errors for missing descriptions on tag pages. I am unsure how to fix these errors, as we do not actually have pages for these on our WordPress site where we are able to put in a description. I have heard that having tags can be good for SEO? (We don't mind having several links that show up when searching for us on google...) As far as the SEO goes, I am not sure what to do. Does anyone know the best strategy?

Background Images and ALT text
We pretty much exclusively use background images for our sites. How do I add in alt text? I tried a Google search for this issue and the best answer I could find was "Use the 'title' tag in the containing div", but that was from 2010. Is there a better way to do it? And no, we're not going to switch to using standard images, because background images are way more slick for UX.

How many product subcategories are ok?
Let's say I have a sea glass ankle bracelet. On my site, my main keyword is "Sea Glass Jewelry" and have ranked relatively well for this, but this main page has over 200 products in it. I thought that if the URL has the keywords in it, it would be beneficial. I also have a section for all my bracelets, so it would be there and then, a more specific ankle bracelets category. So, technically, an ankle bracelet will show up 3x. Sea Glass Jewelry (all products go here) Bracelets (all bracelets go here) Ankle Bracelets (only ankle bracelets) The URL is only attached to the main category so to speak. If you click the ankle bracelets category, the url will still revert back to the original main category: seaglassjewelry/sterlinganklebracelet so I don't believe there is duplicate content. I have had my domain for years and it has ranked well until someone hacked into my site 2 years back. I have never been able to recover from this loss. Since then, I have tried to optimize my site, but nothing seems to be working and I just want to make sure that I am not hurting my ranking by doing this. Can someone confirm this is the best way to do it or make a suggestion? Thank you.

Should I add PDF manuals to my product pages?
Hello. A lot of the products I sell on my e-commerce site are very technical. I decided to add PDF data sheets, manuals etc on each of the product pages to improve the customer experience. Now I am not sure if it was the best thing to do. I have noticed a couple of times that the PDF is out ranking the product page in the SERP. For a few products, the PDF ranks but the product page doesn't. Anyone got any ideas?

H1 tag in the footer?
Quick question: I have been scouring SEOMoz.org along with webmaster forums looking for an answer, but we have a person who insists that the H1 tag be located in the Footer. I feel that is is fundamentally wrong because it is not the intent of the H1 tag, and I do not believe it is a best practice. That being said would we see what little value the H1 tag has disappear if we put it in the footer, would we be penalized, or am I being too vanilla by wanting to keep it in the Title position?

Using commas in the title tag?
Is there a disadvantage/advantage to using commas to separate words in the title tag. Which will be more effective as a title tag: "keyword1 keyword2 - Brand" OR "keyword1, keyword2 - Brand"?
