Dropping The iframe for SEO
However, this presents an issue with search engines, as they do not guarantee that the content in the iframe will be attributed to your site.
Now, when rendering comments, the embed script will check if the page is being loaded by a crawler. If so, it will not use an iframe!
How Many Comments Are Shown
Up to 2,000 comments will be shown to search engines for a page. They will be sorted based on your default configured sort order.
The Testing We Did
We ensured that search engines now see the entire comment thread for a page, and we tested the performance of loading entire comment threads at once.
Impact to Existing Customers
If you're an existing customer using FastComments, the change has already been applied to your account, and no further action is required. Once search engines re-index your pages all comments on those pages should be indexed.
We hope you found this update and its documentation useful. Happy commenting!
