I've created some small sites that give reviews for products.
I'm not an SEO expert and I'm not enough time to do SEO.
I saw that on Fiverr or SeoClerk that are selling some backlinks or full SEO packages.
I'm wondering that whether these services are safe today.
For example, how could they sell us the backlinks that have contents, relate to our keywords? The non-related backlinks can make our site more badly.
Are there any suggestion or experience about this?
