I just switched from prod Id urls to title description urls.
Now when I try to link using the title url in Facebook the pictures are not being fetched and sometimes the links are not working.
Anyone have any hints to what I'm doing wrong?

Here is an example.
https://www.offshoreelectrics.com/proddetail.php?prod=Roll+of+Hatch+Tape+%281.5"%29

There are certain characters that are Forbidden in a URL, like ...

” as in 1” is forbidden. 1 inch is fine.

Read more about [url="https://perishablepress.com/stop-using-unsafe-characters-in-urls/"]unsafe characters you cannot use in URL’s[/url]
You have quickly discovered the limitations of SEO friendly URL’s.

When Facebook scrapes a page URL for the very first time, it only looks at/requests part of the content, returning a “HTTP response code 206”. Thus it generally does not gather the og:image filename the first time. Yes, that is very strange, but if you run some URL’s through the [url="https://developers.facebook.com/tools/debug/sharing/"]Facebook Debugger Tool[/url] take note that is exactly what happens.

If you then click the “Scrape Again” button ... Voila ... Now you see the proper result with og:image displayed.

When switching to the SEO Friendly URL’s, there is one small change that needs to be made to dynamic code that prints the <canonical> and og:url entries.
Look at [url="https://www.ecommercetemplates.com/support/topic.asp?TOPIC_ID=104554"]this topic here[/url] and read the second post.

Thanks Gary. I swapped from TRUE to FALSE and Im still getting the same urls. Is there something else I can look into?

Switching TRUE to FALSE fixes the canonical and og:url lines in the source code. (check that)
You will get the same URL
Cannot use certain characters in the Product Name.

Roll of Hatch Tape (1”)
Roll of Hatch Tape (1.5”)

Cannot use “ character.
