Internal linking is one of the most underused SEO tactics for new site builders. It costs nothing, requires no technical skills, and has a measurable impact on how Google understands and ranks your pages. Yet most new micro site owners either ignore it entirely or do it randomly without a strategy.
What internal linking actually does
When you link from one page on your site to another, you are doing two things simultaneously. First, you are giving visitors a clear path to related content, which keeps them on your site longer and improves engagement signals. Second, you are passing what SEO professionals call link equity or PageRank from one page to another — telling Google which pages on your site you consider most important.
The hub and spoke model for micro sites
The most effective internal linking structure for a micro niche site is the hub and spoke model. Your hub is your most important page — typically your main tool, your cornerstone article, or your homepage. Your spokes are your supporting blog articles. Every spoke links back to the hub, and the hub links out to the most relevant spokes.
For GetNicheIQ, the hub is the niche validator tool on the homepage. Every blog article about niche research, AdSense, and micro site strategy links back to the homepage with anchor text like "validate your niche idea" or "check your niche with GetNicheIQ." This concentrates link authority on the most commercially important page.
Anchor text — the words you use matter
The clickable text in a link (called anchor text) tells Google what the linked page is about. Generic anchor text like "click here" or "read more" wastes an opportunity to reinforce your target keywords. Descriptive anchor text like "AdSense niche validation tool" or "how to validate a micro site idea" gives Google clear signals about the linked page's topic.
Use your target keyword phrase as anchor text when linking to important pages — but vary the phrasing slightly across different links to avoid looking unnatural. Three links all using the exact same anchor text looks manipulative. Three links using naturally varied phrases looks like editorial choice.
How many internal links per article
There is no hard rule, but a practical guideline for a micro site article of 1,000 to 1,500 words is two to four internal links. Each link should feel natural — placed where a reader would genuinely benefit from exploring the linked topic. Never force internal links into places where they interrupt the reading experience. Quality and relevance matter more than quantity.
Linking new articles to old ones
Whenever you publish a new article, go back to two or three of your existing articles and add a link from them to the new piece where it is relevant. This gives your new content immediate link equity rather than leaving it isolated with no internal links pointing to it. It also signals to Google that your site is actively maintained and that new content is worth crawling.
The orphan page problem
An orphan page is a page with no internal links pointing to it. Google may still index and rank orphan pages, but they accumulate link equity more slowly and are harder for visitors to discover through your site. Check that every page and article on your site has at least one internal link pointing to it from another page. Your blog index page should link to every article, giving each at least one internal link by default.
