It does matter what the rest of the site looks like. If everything outside of the one article I can provide looks buggy or unprofessional, it can often get the link reported as spam.
Generally, yes, but I'd have to see the site where it would be hosted.
I don't believe I did, you might want to resend it.
After a few days I typically delete the links. I do this for the security of my accounts and the security of the client's website. 99.99999% of the traffic you would ever get from the submission will show up in the first couple of days. All of the social shares (hundreds to thousands) and reposts you get out of it will contribute to your website's backlink profile. Deleting one of those backlinks isn't going to hurt your website.
Thank you very much! Your website was super easy to get to the front page!
I don't have a website, you can contact me either here or on skype -
