Hi,
In our website www.viatrading.com we have many products that might be in stock or not depending on availability.
Until now, when a product was not available anymore, we took this page down (and redirected to its product category page). And, only if the product was available again, we re-activated the URL - this might be days, months or even years later.
To make this more SEO-friendly, we decided now that while a product is not available, instead or deactivating/redirecting the page, we will leave it online and just add a message saying "This product is currently not available".
If we do this, we will automatically re-activate about 500 products pages at once.
1. Just to make sure, is it harmful for SEO to keep activating/deactivating URLs this way?
2. Since most of these pages have been deindexed for a long time due to being redirected - have they lost all their SEO juice?
3. How can we better activate these old 500 pages - is it ok activating them all at once?
Thank you,
