HubKarma is a score that reflects the degree to which you link to others' Hubs and to Topic pages in your own Hubs. Hubs that point to other relevant, high quality Hubs enhance readers' experience on HubPages and improve HubPages credibility as a trusted resource. HubKarma has a small influence on your Hubber Score and is on a 0-100 scale. The link suggestion tool makes linking to other Hubs and Topic pages easier.
The link suggestion tool is a tool for your Hubs that makes it easy to add links to your other Hubs, other authors' Hubs, and topic pages. To use the link suggestion tool, sign in to HubPages and navigate to one of your Hubs. You will see a button near the top of the page that says "suggest links." Click on the button to reveal link suggestions for your Hub, as well as more detailed instructions for using the tool. The link suggestion tool can be used to improve your HubKarma.
