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.

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

Product content length & links within product description
Hello, I have questions regarding content length and links within descriptions. With our ecommerce site, we have thousands of products, each with a unique description. In the product description, I have links to the parent category and grandparent category (if it has one) in the main product text which is generally about 175 words. Then I have a last paragraph that's about 75 words that includes links to our main homepage and our main product catalogue page. Is the content length long enough? I used to use text that was 500 words, and shortening it I still rank when launching new products, so I don't think an increase in text length will have any additional benefit. I do see conflicting information when I do searches, with some people recommending a minimum of 300 words and some saying to try and go a 1000 for category pages. In regards to the links, I noticed a competitor has stopped following this format, so I'm unsure if I should keep going too. Is it too many links to have each of the products link back to the main catalogue and homepage? Is it good to have links with anchor text to the categories a product is in? There are breadcrumbs on the page with these links already. There are already have heaps of links on our pages (footer, and a right sidebar with image links to relevant categories), so my pages do get flagged for too many links. Thanks!

Multiple menu items pointing to same page
I have an automotive dealer as a client. The primary nav has a finance menu item, which (of course) points to the finance related pages. He just requested that I add a finance link item, as child menu items, under the new and used car nav items. Now, this is wrong for a host of reasons, what is the best way to communicate to this to him? I mean, I see this as a usability issue, it's wrong thematically, we would end up having 3 links pointing to the same page. Would this classify as dupe content?

Should I watermark my product images
I am in the process of creating new images for my products to use on my website. Are there any advantages or disadvantages of watermarking each image? Is there an SEO impact good or bad? I am aware that filename and Alt tags are important, but am unsure if google dislikes watermarked images.

Selling Products with a similar meta description
Wondering if anyone can help when selling similar products with very similar meta description and product descriptions in general. Have around 500 products - a lot of products have around 10-20 products which are very similar only different is sizes and a maybe a few lines of text if that. Is this a problem in search engines? How does other ecommerce stores selling similar products solve this problem...

Does it matter what text you wrap in an H1 tag?
Typically H1 tags are reserved for page headings, i.e. on a blog post the blog post title is very often the pages H1, or top-level heading as the W3C puts it. On the SEOmoz home page they currently have "SEO Software." as their H1 tag, which seems perfectly reasonable and to me fits the W3C criteria. However, what if the primary keyword for SEOmoz was "seo community" so they decided to wrap just those two words in the sentence that follows on their home page and maintain the existing style of the words "seo community" with CSS. (see attachment) Are there any arguments against doing that? Would Google be able to detect this? If so, would Google care? I do believe the overall importance of the H1 tag has lessened to a degree, however I still believe they are valuable to an extent and would love to hear anyone's thoughts. 7NZcD.png
