Keyword Lighthouse Pro is a lightweight Chrome extension
that helps you uncover long-tail keywords—quickly, cleanly, and without
paid APIs. It does one job exceptionally well: harvest hundreds of real
search suggestions from Google’s autocomplete, then organize them so you
can build content that ranks faster.
How it works
When you click Start Harvest, the extension builds smart
variations of your idea. It can append A–Z letters (e.g., “portable
blender a…z”) and apply your custom modifiers (“near me,” “best,” “for
beginners,” “how to,” “2025,” etc.). For each variant, it queries
Google’s public suggestion endpoint and pulls back what real users are
actually typing. You’ll typically generate a broad, high-intent idea
list in seconds—no API keys, no logins.
To keep your list focused, there’s a built-in word-count filter
(default 3–15 words). This targets long-tail phrases—searches with
clear intent and usually lower competition. The extension
automatically de-duplicates entries and caps at 500 results to avoid
noise. Suggestions display under the Export tab in a simple table so
you can scan and act immediately.
Key features you’ll use every day
A–Z + Modifier Expansion: Instantly fan out one
seed idea into hundreds of real queries, including different orders
(e.g., “how to X” and “X how to”).
3–15 Word Filter: Zero in on long-tail phrases that
are easier to rank and often convert better.
Two Extra Columns (optional, no paid API):
Keyword Difficulty – a transparent, on-device estimate
to gauge how contested a term may be.
Monthly Volume – a rough, on-device proxy to sense
interest levels. (You can later swap in live metrics via a proxy
server if you connect to a provider like Google Ads, Semrush, or
Ahrefs.)
Copy All & CSV Export: One click to grab the
entire suggestion list or download a clean CSV with Suggestion,
Keyword Difficulty, and Monthly Volume columns.
Clear & Restart: Wipe the slate and iterate
fast on new directions.
Polished UX: White background, blue tabs,
responsive layout, and results rendered below the Export tab just like
you expect.
Why it helps you rank faster
Ranking quickly isn’t just about more keywords—it’s about choosing the
right keywords. Keyword Lighthouse Pro centers your workflow on
long-tail intent, which gives you three advantages:
Lower Competition: Multi-word queries are less
crowded. You’ll find terms with commercial intent (“best,” “review,”
“near me”) and informational intent (“how to,” “for beginners”) that
big competitors ignore.
Higher Conversion: Long-tail searches are closer to
action. If you publish content that mirrors the phrasing and intent of
these queries, you’ll capture visitors ready to sign up, buy, or
contact.
Faster Content Planning: By pulling grouped queries
at scale (A–Z + modifiers), you can outline clusters—pillar posts plus
supporting articles and FAQs—in one sitting.
A simple, repeatable workflow
StarKeyword Lighthouse Pro is a simple Chrome tool. It helps you find
many long-tail keywords fast. Long-tail keywords are longer phrases
people type into Google. They are easier to rank for and can bring you
the right visitors to your website.
What this tool does
Finds real search ideas from Google’s autocomplete.
Expands your idea with A–Z letters and extra words (called
modifiers).
Lets you filter results by word count (for example, 3 to 15 words).
Shows results in a clean Export tab.
Lets you copy all ideas or export to CSV.
Shows two helpful columns: Keyword Difficulty and Monthly Volume
(simple on-device estimates with no paid API).
Why this helps you rank faster
Less competition: Longer phrases are not as
crowded, so it’s easier to get on page one.
Better intent: People using longer phrases often
know what they want. They are ready to learn or buy.

posts, FAQs, and product pages in minutes.

Understanding the columns
Suggestion: The keyword idea you can write about.
Keyword Difficulty: A simple estimate of how hard
it may be to rank. Lower is easier.
Monthly Volume: A simple estimate of interest.
Higher means more people may search for it.
Note: These numbers are local estimates made on your
device. You do not need any paid API. If you want official data later,
you can connect a paid provider. The table will still work.
