Geebo prides itself as a safe community of classifieds where users can post anything from selling merchandise to looking for roommates to renting a house for free. You can also connect with them using your social media account. While not as popular as its counterparts, Geebo has been around for some time and has built itself quite a strong following.
Since guest posting on a popular blog allows you access to an established audience and high domain authority, this practice can sometimes be more beneficial than posting to your own blog. Plus, you can link back to your own website from your article, giving you an inbound link that boosts your domain authority and can increase your own website's ranking in search engines.
