Google still has not added native options to follow Google+ users via RSS on its social networking site. Ever since Google+ was launched by the company, users tried to come up with ways to generate RSS feeds for profiles on the site to follow users in RSS clients such as Google Reader, RSSOwl or my personal favorite Great News.
Instead of having to visit Google+ regularly, it is then possible to monitor new posts via RSS. Users who do that can then decide whether they want to visit the Google+ page, for instance to join the discussion, or ignore the post and wait for posts that are more of interest to them. Google+ feeds basically give you control over how and when you interact on the social networking site.
Back in 2011 I posted a tutorial on how to use Dapper for the purpose, and while it worked sometimes, it did not really work at others. Plus, the setup was rather complicated and not really suitable to quickly generate RSS feed links from Google+ profiles.
The free GooglePlusFeed online service provides you with the means to generate an RSS feed from any public Google+ profile. All you need to do is visit the service website, enter the profile ID of the Google+ user that you want to generate an RSS feed for, and an email address for verification purposes. If you do not want to reveal your real email, you can check out our list of disposable email providers to use one of those temporary addresses instead for privacy reasons.
You find the profile ID of a user when you open the user's profile home on Google+. Just copy and paste the string from the address and paste it into the profile ID field on the Google Plus Feed site. (Check out mine, and while you are at it, why not subscribe as well)
GooglePlusFeed sends a confirmation mail to the email account that you have entered into the form, and once you load the verification link, it displays the RSS feed on its site. You can then copy the RSS link to your feed reader, and repeat the process if you want to subscribe to additional users of the site.
Keep in mind that the RSS feed will only catch public posts, and not private or limited posts, nor messages from one Google+ user to another.
Check out NirmalTV for two additional services that allow you to generate RSS feeds for Google+ profiles.
Update: Google Plus Feed RSS is no longer available, the server returns a 404 not found error. You can use the following alternatives instead:
