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.

Should posts show in multiple categories?
Hi all, For context, I'm trying to Silo my content more efficiently. I've just moved all content into their own SILO'd categories and removed them from duplicate categories. As such, posts now sit only in 1 category. My question here is: Should my posts be showing in both the parent category and its sub category or just the sub-category? I've currently got this only showing in the sub-categories it's relevant to. For example:

Post name: Shimano Fishing Rod Review
Parent Category: Fishing Rods
Sub Category: Shimano And the post only shows inside the Shimano Category0 -
Canonicalising a product with multiple variants
I am working with an ecommerce site and have encountered an issue I haven't come across before and would appreciate some advice on how to proceed. There are multiple variation products with one master product and then up to 20 or 30 variant products, the variation could be colour, size or both. The site has been set up to canonicalise all the variations to the master variant product, which I understand to be best practice. But, this is where the issue occurs, the master variant product URL 302 redirects to one of the variant product URLs. Example below. My question is, is this harmful to our SEO efforts? Would be be best to canonicalise to a preferred colour or size variation? EXAMPLE: Master variant product: www.example.co.uk/primary-category/product-123 Seeing this product on the page and clicking will 302 redirect to www.example/co.uk/primiary-category/product-123/colour-456 On page www.example/co.uk/primiary-category/product-123/colour-456 the canonical tag is www.example.co.uk/primary-category/product-123 Any help with this would be greatly appreciated.

Will it upset Google if I aggregate product page reviews up into a product category page?
We have reviews on our product pages and we are considering averaging those reviews out and putting them on specific category pages in order for the average product ratings to be displayed in search results. Each averaged category review would be only for the products within it's category, and all reviews are from users of the site, no 3rd party reviews. For example, averaging the reviews from all of our boxes products pages, and listing that average review on the boxes category page. My question is, will this be doing anything wrong in the eyes of Google, and if so how so? -Derick

Duplicate content with tagging and categories
Hello, Moz is showing that a site has duplicate content - which appears to be because of tags and categories. It is a relatively new site, with only a few blog publications so far. This means that the same articles are displayed under a number of different tags and categories... Is this something I should worry about, or just wait until I have more content? The 'tag' and 'category' pages are not really pages I would expect or aim for anyone to find in google results anyway. Would be glad to here any advice / opinions on this Thanks!

Less Tags better for SEO?
I am currently reviewing my strategy when it comes to categories and tags on my site. Having been no-indexed for some time, and having many tags with just one entry I am thinking that this is not optimal for SEO purposes. This is what I am planning: Categories - Change these to Index, but only after adding a hundred words or so by way of introduction (see this example - https://www.besthostnews.com/news/hosting/a-small-orange-news/). With the categories I am thinking of highlighting key articles as well to improve link juice distribution to older articles that are important. Tags - About half my tags have only 1 entry, with a few more just having 2 entries. I am thinking of deleting all tags with just one entry, and trying to merge those with just two or 3 entries where it makes sense to do so. I will keep these as no-index, but I think this will mean more optimal distribution of link juice within the site. I would appreciate your thoughts \ suggestions on the best practices here.

Break in H1 tag - big, small or no problem?
Hi, I've just taken on a new ski client who offers ski instructor courses. The landing page for the keyword [ski instructor courses] was created by the web agency but with no heading tags... http://www.snowrehab.com/ski-instructor-courses Subsequently they've put them in but I've noticed the H1 tag has a break in it where 'ski' is on a separate line to 'instructor courses' Is this an issue that need to be addressed? Also I can't look up the page in the Moz on-page grader - any ideas why? Many thanks! Richard

H1 Tags on Volusion Product Pages
So I'm working with a client who has no heading tags on his site and I'm wondering if there is an ideal method to implementing these on the product pages specifically, as the wording I ideally want to specify is is the product title, which i can't really code with an H1. Has anyone run into this issue? If so, what was your solution? Also, how vital are these heading tags on the product pages, anyways? If the Volusion SEO expert could chime in, that would be much appreciated. Thanks everyone!
