SERP
The page you see after typing something into Google. It's where all the search results live—ads at the top, organic results below, and sometimes featured snippets, maps, or images mixed in.
Keywords
The words and phrases people type into search engines when they're looking for something. Your job is to figure out which ones your audience uses and make sure your content shows up for them.
Long-tail Keywords
Longer, more specific search phrases that fewer people search for but are way easier to rank for. They usually convert better because the searcher knows exactly what they want.
Backlinks
Links from other websites pointing to yours. Google sees these as votes of confidence—the more quality sites linking to you, the more trustworthy you appear to search engines.
Domain Authority
A score (1-100) that predicts how well your entire website will rank in search results. It's based on factors like backlinks, age, and overall trustworthiness. Higher is better.
