Is PR worth doing for small businesses?
In what ways do you think startups and small businesses can benefit from PR?

Depends what you mean by PR - if you're a business that makes, let's say industrial rope - then clogging editors' and journalists' inboxes with releases about rope day in, day out won't help you any.
However, if you're creative and you can pitch interesting stats or insights into rope to an industry publication; let's say RopeBlogger - then that's worth a bit more.
With any good PR campaign, you have to look at who you are targeting, what return you're looking for (goodwill? brand recognition? sales?) and how you can measure your investment (with time or money.)

PR is important for the Small businesses to expand their reach and promote their services to the large pool of audience, for example if you are looking to serve customers beyond numerous cities, release a press to promote as you are not doing a common thing, i just post a press release explore it here http://bizpr.co/2016/09/28/get-trending-statistical-techniques-data-collection/

Yes Rick. It totally is! I have been teaching small business owners how to do their own PR for the last 7 years and have watched some of my students get publicity they had transformed their business. It gives your business credibility, increases word of mouth, it's free and it positions you as an expert if your product as a 'must have'. I would thoroughly recommend you give it a try. You just need to find your story if offer tips that will genuinely help people. Take a look at my website if you want to know how! PS. There is a whizz bang new website launching in about 3 weeks so if you register you'll get to try it out!!
