Automated cross-platform social sharing

I have an affiliate website with around 50+ articles. The articles are fairly well-written, 1000+ words, unique and with most focusing on a product, containing a description, pros and cons, conclusion etc etc. The content is pretty informative in my eyes but I am looking to gain more traffic (and to increase ranking) for these articles.

At the moment, I have no social media presence for this website. I have empty twitter/FB accounts but what I am looking for is the following:

A tool/service that will:
-Post new content automatically on twitter/FB page when posting and;
-Post old content automatically on the twitter/FB page (possibly with randomized hashtags). With over 50 articles, posting an article bidaily should make it that it takes 100 days for all content to be posted once, after the cycle starts again.


Is there such service/tool available? How would you go about this? I am really looking into gaining more social media traction but as I am the only person working on the site, with quite a bit of content, and with limited knowledge of (automated) social media, I would love some pointers. I am not looking to spam or anything of the sorts, I believe my content is worth posting, it's just not particularly viral/shareable by nature so people don't share my articles by themselves.

Thank you in advance for your thoughts.

Biffer/Hootsuite will assist in automating your posts. I'm afraid you'll have to do the second task manually

Look into IFFFT logic setup!

i think the best is iffft ...
