I usually do the first promotion on social media "manually". Once my blog post has just been published, I post it manually on my Facebook page, my Facebook profile, in various groups (including my own), on LinkedIn and Google Business. Depending on your niche, Pinterest can also be an extremely valuable traffic provider for you. I see Pinterest as a mixture of search engine and social media.
For further social media management, a estonia telegram screening teaser text then goes into the Publer * tool and I post it automatically at longer intervals without having to worry about it any further.
Publer has a very fair and affordable pricing system, is based in Europe and has friendly, fast support. Publer also takes great care not to violate the rules of social media channels.
