This may seem like a strange question as the product description is part of the dynamic data that is transferred to the product page and many may think that it is working for SEO since it shows as the Google search result "description and title" But I assure you it is not being used properly for SEO and search engines will penalize you (and me) for the way the product page is indexed.
I have ran audits on my site for over a month and I have been submitting crawl requests since the day I got the "base info" of the site skeleton finished (this means with main content with no blog or FAQ) and still even tonight when I ran the audit I was flagged with 84 pages with REPEATING TITLES & DESCRIPTIONS. Even though google shows the product description in google search, that IS NOT the description that is indexed when the product pages are crawled and indexed.
Mine all have the Title of the Home page and the description given on the home screen and every other page that Wix doesn't allow us to edit. If I wasn't on a deadline when I built this site, I would have used Drupal or Wordpress because they leave me with complete freedom to add and change what is necessary to get my pages indexed with the proper content.
Is there ANY WAY to change these settings by making a database full of descriptions and linking that dataset to an html block or some other way to drop the desired code to each page? I mean other than skipping the dynamic page idea and just building an individual page for each product...
The product pages are not the only pages that are affected by Wix's way of sorting and blocking their own code. Upon performing audits for this long I have noticed a ton of things. Text added to sliders, on images, in boxes, switch boxes, strips, etc.. None of that text gets read by search engines as anything substantial. I ran audits time and time again and it came back with errors for not having H1, H2, or H3 tags when they were in plain site on the page. It read that there were no matching keywords other that title and description because no content on the page was indexed or able to be read by the audit.
The alt text for images DOES NOT show up. and the IMAGES themselves don't show up unless they are the base layer on the page, because as soon as you place the image on a slider or a box or anything to add style, the alt text is no longer visible. This is a serious issue. And I logged these audits in real time after making changes and republishing before performing a live audit each time to try to fix the issues and these issues can not be fixed.
If anyone else has looked this far into it and noticed this let me know.
