Internal linking is creating links to content on the domain where the link originates. Basically it means linking to yourself.
Why Link To Yourself?
1. For people
First and foremost, to help your visitors find your content. If you have a page about underwear, and you mention the word underwear in another post, changing it to a link to your main underwear page helps visitors find you content easier.
2. For Robots
Search engine robots like to follow links to get to pages and also value pages based on how many links they have pointing at them, even from your own domain. Give the bots the easiest way to crawl your site, link to your own content often.
An Easy Way To Do Internal Linking
Many people are familiar with a plugin for wordpress that changes specific words to affilaite links. Well you can use similar plugins to link internally on your site.
Instead of sending your visitors to affiliate sites, send them deeper into your own site.
My favorite is Wordpress Alinks.
I’m terrible with remembering to link to my own content from within my posts. With Alinks I set up a word/link pair and the plugin does it for me.
For instance, I can go into Alinks and tell it “every time I mention underwear please change that word to a link to my underwear page”. And that’s it. You can do this over and over for keyword/link pairs and Alinks does the rest.
