SERP
Search engine results page — everything the engine shows for a query: links, snippets, images, ads.
What it means for a site you run
The SERP is the competitive landscape: what ranks there defines what a winning page must be — format, depth, freshness. Ranking work that ignores the SERP is guesswork; a query whose results are all videos needs a video, not a blog post.
How Blogotter relates
The day before an article is due, Blogotter reads the live search results and fetches its sources, and the draft is written against what it found, not against a static brief.
