Internal linking on a small rental website
Links from one of your own pages to another are one of the cheapest, most overlooked ways to help both visitors and search engines understand your site.
Every page on your site should link to, and be linked from, at least one other relevant page. A property page should link to your area guide and your contact or booking page. Your area guide should link back to the specific properties it mentions. A page with no links in or out is a dead end — for a visitor deciding what to look at next, and for a search engine trying to work out how the page relates to the rest of your site.
Link using words that describe the destination page, not "click here" or "read more". A link reading "our pet policy for guests with dogs" tells both the visitor and the search engine what's on the other end before they click; a link reading "click here" tells them nothing until they do.
If you write guides or blog posts, link back to the relevant property or area page from inside the guide, in the sentence where it's actually relevant — not only in a sidebar. A guide about hiking trails near your cabin, linking to the cabin's page from the paragraph about the trailhead closest to it, is more useful to the reader and a clearer signal than the same link sitting in a generic "see also" list.
Check occasionally for links that go nowhere — a renamed page, a removed listing — since a site with several broken internal links reads, to a visitor who hits one, as unmaintained.
