Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
Good stuff, Brian. The tip about getting longer (4-line) descriptions is awesome. I hadn’t noticed that too much in the SERPs, although now I’m on a mission to find some examples in my niche and study how to achieve these longer descriptions. I also like the tip about using brackets in the post’s title. One other thing that works well in certain niches is to add a CAPITAL word somewhere in the title. Based on some early tests, it appears to improve CTR.
The great thing about the long tail for new sites that have no backlinks and no authority, is that it is possible to rank for these terms, assuming great on-page SEO, quality content etc.. So therefore focusing on the long tail is a strategy that is often recommended and in fact Rand himself (and indeed others of good repute) have cited 4+ words and lower LMS to avoid the med-high volume kws due to their kw difficulty. Have I completely missed the point in your guide or do you indeed have a slightly different view on the long tail?
Organic search results are free and display below Google Ads and sometimes local results. Google uses a sophisticated algorithm to determine which sites rank highest for organic search results based on keyword usage, relevance, site design, and other factors. Generally, Google provides the highest quality, most relevant results based on the keyword(s) used by the searcher.
