Copy pasting my reply to your email for reference:
Thank you for your query about my plugin WooCommerce Product Table. I will be happy to answer.
The URL you are seeing with this parameter: ?sbbpg=sbbShell&gprid=ow&sbbgs=h465f79595721f8d047685b08d91206c5b49&ddl=-46823 is not generated by the product table plugin. I can assure you of this, there is no code in the plugin to create these URL parameters.
WooCommerce Product Table does modify the URL as the site visitor is going through different filters and different pages of the product table. This is done so that the visitor can copy the url and use it in the future to return to that exact view of the table with the same product results so browsing products and keeping track of the past browsing is made easy for them.
But the specific URL parameters you have shown me are not part of my plugin at all. So I can tell you that this link is not created by my plugin.
Also, even though WooCommerce Product Table does modify the url as the visitor is navigating through the table filter and pages, this does not affect what the google seo crawl bots see on your site at all.
The URL only changes when the table’s navigation (pagination, filters) is being used and the google crawlbots do not click on it, or see the modified URL either. So there will be no SEO issues.
I hope this information helps clarify your question. Please let me know if there is anything else.
