Yes, there is a strategy to using hashtags on social media platforms. Use hashtags sparingly and only when they add value and meaning to the words in your post. Overdoing it with how many words you hashtag in a single post, or how many words you put into the one hashtag can be confusing, ugly, and quite truthfully annoying.
In May 2018, the EU’s GDPR comes in force. Companies and organisations need to make sure they are in compliance or risk facing serious penalties. This also applies to websites.
Using more and more social media platforms does not necessarily mean more success with online presence and branding. The same holds true with having too many profiles/pages. In fact, it can very well be counterproductive and cannibalise online activity and credibility. Much better to choose only a few, use them regularly, and use them well!
