Writing material with great SEO potential can be a challenge. You need to get a good balance of keywords without being accused of keyword stuffing – a big no no in SEO world. That basically means all of your content is keywords and it makes no sense, has no real information and is just there to, well, have a lot of keywords present.
Authority may seem an easy one. Someone in authority has to be answered to and the same applies here. It means the level of trust that a site has from the major search engines. If the trust is high that's good, and it means the site will rank high. If not, it won't and that's bad news.
Bread crumbs are a great ingredient for meatloaf, and they work well in fairy tales for characters to get back to where they started from. In SEO speak, bread crumbs are website navigation tools that help visitors get back to where they want to be within the site.
We have many doorways in our homes. They are used to enter and exit a room. In SEO a doorway has a similar function in that they are pages that are used to specifically attract traffic from the search engine. Then the user will 'enter' the site. See what they did there?
Content in SEO speak means the specific parts of a site that have the most value for the viewer, that is the articles, the meat of the site, the oomph if you will. This is not the place for advertising, branding or navigating.
There are airports around the country that act as hubs for various airlines. If you get to one of these hub airports you can usually connect to pretty much anywhere else. Same is true of a hub in SEO. A hub is defined as an expert page that is high in quality (information, no keyword stuffing, etc) and it links the user to other related pages to further enhance their search.
An inlink may sound like something on a golf course but for our purposes it means inbound links from other related pages (like the hub) that are already a source of trust. You can inlink to another page and back to get more information on your query as a user.
And lastly, a walled garden isn't what you think. Instead it's a group of pages linked together but not linked to any other pages. So you're stuck!
