The phrase gets used for new queries with weak competition, and that is the harder version. On a site with any history at all, the genuine easy wins are already there: pages that nearly rank, pages that rank and are not clicked, pages competing with each other, and queries you answer accidentally. All four are cheaper than a new page because the page exists, the site already has some standing on it, and the change is measured in hours.
Pages sitting just off the first page
A page averaging somewhere between eleventh and twentieth for a query with real intent is the best-value work available on most sites. It is already close, the subject is already one the site is credited for, and a genuinely better answer often moves it. Find them in the Performance report by filtering to the queries where average position sits in that band and impressions are meaningful.
Pages that rank and are not clicked
High impressions and a poor click share usually mean the title and description do not match what the searcher wanted, or the page is ranking for an intent it does not serve. The first is a fifteen-minute fix with a real return; the second is a signal that a different page should hold the query. Neither requires writing anything new, and both are invisible unless you look at queries rather than pages.
Two of your pages competing for one want
When a site has published on a subject over years, it usually has two or three pages answering the same question in different words. They split the signal and the search engine picks one, often the older and weaker. Consolidating them into the best one, and pointing the others at it, is a day's work that regularly produces the biggest single movement on a small site.
Doing this before new research
All four of these come out of data you already have, cost hours rather than weeks, and have a shorter feedback loop than a new page. Working through them first also tells you something about your site that no keyword tool can: which subjects it is actually credited for, which is exactly what should shape the new research afterwards.
Questions people ask about low hanging fruit keywords
What are low hanging fruit keywords?
Queries where a small amount of work has a good chance of a real return, which on an existing site usually means pages that nearly rank rather than new queries.
How do I find them?
Search Console's Performance report: filter by query, look for average positions just off the first page with meaningful impressions, and for high impressions with a poor click share.
Is this better than writing new pages?
Usually first, yes. The feedback is faster and the site already has standing on the subject.
How does Longtailo help?
By keeping the list of these candidates with the page each belongs to and the position you logged, so the ones you fixed and the ones you have not are distinguishable next month.
