When a domain name that was previously registered expires, it goes through a grace period that allows the previous registrant one last chance to reclaim their domain before it becomes available to new buyers. If the previous registrant still has not renewed their domain after the 77 day deletion process, the domain name will officially expire and enter the Aftermarket.
Trust flow refers to the number of quality backlinks that a website has. If backlinks from websites that have a high domain and authority ranking point to your site; your website’s trust flow will increase. Trust flow is also measured on a scale of 1 to 100. If your website has a large number of backlinks, but they are not from trustworthy and reliable domains, your websites trust flow will be low. On the other hand, if you even have just a handful of backlinks to sites that search engines rank highly; your trust flow will increase.
