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.

What heading tag to use on sidebars and footers
Hello, I have some awareness of how to use H1, H2 and H3.
On-Page Optimization | | kowston
H1 only once per page as the main page heading.
H2's should be subheadings, H3's are sub-sub headings of the and so on.
This structure gives hierarchy and opportunities to use additional keywords in an order of priority. I can clearly understand how this would work in an article but what about other content on the page such as global/frequently repeated elements like sidebars and footers? I see sites - and in particular, I have examed SEO focused sites - that use H3, H4 and H5 in these instances seemingly giving themselves scope to use at least H2 tags as part of the page content and break out of the structure hierarchy when dealing with sidebars and footers. I suppose this could signal theses headings are sections of the page that are less relevant than the main article content but that is just an assumption. I don't know what is correct.0 -
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.

SVG image files causing multiple title tags on page - SEO issue?
Does anyone have any experience with SVG image files and on-page SEO? A client is using them and it seems they use the title tag in the same way a regular image (JPG/PNG) would use an image ALT tag. I'm concerned that search engines will see the multiple title tags on the page and that this will cause SEO issues. Regular crawlers like Moz flag it as a second title tag, however it's outside the header and in a SVG wrap so the crawlers really should understand that this is a SVG title rather than a second page title. But is this the case? If anyone has experience with this, I'd love to hear about it.

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.

Is it OK to include name of your town to the title tag or H1 tag on a blog to enhance local search results
I recently attended a webinar by ETNA Interactive on local search SEO. The presenter recommended including the name of your town in the title of the blog to increase local search SEO. Is this OK? Ive always been concerned that it is such an obvious attempt to rank locally that Google would consider it "spammy" ? black hat, "sketchy" or otherwise manipulative. Have the rules changed? Is it OK to do? Brooke

How to separate your - keywords - and | Brand name in the Title Tag
I have traditionally used hyphens (-) and vertical bars (|) to separate out keywords/brands in title tags. A client has asked if other characters will work such as tilde (~), apersat (@), forward slash (/) etc. Are there any special characters we should steer clear of?

Do alt tags count towards on page keyword density?
Hello...I have written a bunch of content for my site using a useful tool called Scribe SEO which recommends keyword density at 5% if I remember correctly. So all my my newly written content is below this level but I am left wondering if by adding alt tags with my chosen keywords I will be considered to be over the limit and cause a red flag? Can anyone clarify this for me please?
