Can I link all social media accounts so one post goes automatically to all?
Is there a social media tool, free or paid, to help me do this?
Sure. Sort of. You can link SOME social media platforms via their own functionality. Ie Twitter and Facebook talk together no problems.
Now that FB own IG you can also set up IG to post to FB directly also.
But if you want to do them all you may find the best way is to use a 3rd party program like Hootsuite of tweetdeck.
PS One more thing, just be aware, because of how some o those platform handle information, slightly weird things can happen. ie if you post a picture to FB and auto share it with Twitter the pic won't come up in Twitter, only a link. (At least last time i checked). Same with if you post a longer update on FB then Twitter has to abbreviate it to its own character limit... so people need to click to see the whole thing. Also, if you post to IG and use lots of #tags, they look a bit dumb on FB where no one tags much. So you do need to be a little careful about auto linking - some things are sweet, but some you are better off doing manually separately for the best result.
I would also recommend looking at Buffer (which is similar to Hootsuite).
Another alternative to checkout is IF or IFTTT also known as "If This Then That". It is a mobile app that has tons of easy to setup integrations. It can work around some of the issues mentioned above (like turning a picture into a link - it will keep a picture intact across networks for example).
There is 1 counterpoint I want to mention. There are several sources that are telling people and businesses not to use functions like this for 1 reason. Each social network has its strong points and weaknesses. You should not only tailor your content to your audience, but also the specific social network.
Remember focused content directed toward your target audience is more important that frequently blasting out the exact same content across Facebook, Twitter, Instagram, Pinterest, etc. If you are sharing the same content on all channels why would anyone follow you on more than 1 channel?
You took the words out of my mouth! Yes.... the question to ask yourself is.... Why would I follow you on other platforms if I have the same content delivered across the board. Think of the best way to use each platform to expand your brand and your message. For example, a fashion business might post a great photo of a model wearing a scarf on Instagram. Then, a content post on facebook around the best 3 ways to wear it and ask their audience to send in and post their ideas. On LinkedIn they would post about what is the most appropriate scarf to wear for the job you do or personal branding tips. .... and the like. I like buffer best, still others rave about hootsuite and post planner too. Good Luck!
