Cluster Keywords Straight From Google Sheets

Your keyword list already lives in a Google Sheet. Instead of exporting, reformatting, and re-importing, group those keywords by live SERP overlap without leaving the tab. Send them from a CSV upload or the Optiwing side panel, then paste the clustered results back into your sheet.

What Your Export Looks Like

A working keyword sheet usually has a keyword column and a volume column, plus whatever notes you have added. Optiwing only needs the keywords. It reads the list, clusters by SERP overlap, and hands back a cluster label for every row so you can paste it into a new column.

Keyword	Volume	Your Notes	Cluster (added by Optiwing)
running shoes for flat feet	6,600	priority	Flat Feet Running Shoes
best running shoes flat feet	2,900		Flat Feet Running Shoes
overpronation running shoes	3,300	check intent	Overpronation Shoes
stability running shoes	8,100		Overpronation Shoes

Keep your keywords in one column. Optiwing returns a matching cluster name per keyword, which you paste back as a new column and then sort or filter on.

The Workflow, Step by Step

Get your keywords out of the sheet

You have two paths. Fastest: highlight the keyword column and use the Optiwing Chrome extension side panel to send them to a clustering job. No extension yet? Use File, Download, Comma-separated values to export the sheet as a CSV.

Send the keywords to Optiwing

In the side panel, paste or push the selected cells and start the job. With the CSV path, sign up (100 free credits, no credit card), click +New on the dashboard, and upload the downloaded file. Optiwing detects the keyword column automatically.

Pick location, language, and device

Choose the Google market you actually care about, for example United States, English, mobile. Clustering runs against live SERPs for that market, so the groups reflect the results real searchers see.

Run SERP clustering

Optiwing checks the top 10 Google results for each keyword and groups keywords that share 3 or more of the same ranking URLs. The highest-volume keyword in each group becomes its primary keyword. A few hundred keywords finish in a minute or two.

Paste the clusters back into your sheet

Copy the clustered output as TSV from the side panel and paste it directly into a new column in Google Sheets, or download the CSV and import it. Every keyword now carries its cluster name, ready to sort, filter, or pivot.

Turn clusters into a content plan

Sort by cluster and combined volume to see one page per group. From there, generate an AI content brief for any cluster (25 credits) or drop the clustered sheet straight into your editorial calendar.

What You Get Back

SERP-Backed Clusters

Groups built from real top 10 overlap, not string matching, so keywords land together only when Google treats them the same way.

A Content Map in Your Sheet

Every row gets a cluster label, turning a flat keyword list into a page-by-page plan you can sort and filter in place.

TSV and CSV Round-Trip

Copy clustered results as TSV to paste back into Sheets, or export CSV. The data leaves and returns in spreadsheet-native formats.

Optional Content Briefs

Send any cluster to an AI content brief with headings, questions, and related terms pulled from the live SERP.

What It Costs

Clustering costs 1 credit per keyword, pay-as-you-go. There is no monthly fee to use the Google Sheets workflow, and purchased credits never expire.

Job Size	Credits Needed	Cost	Notes
100 keywords	100	Free	Covered by the 100 free signup credits
500 keywords	500	$5	A typical single-sheet research batch
1,000 keywords	1,000	$10	Basic one-time pack
5,000 keywords	5,000	$35 one-time, or $20/month subscription	A large multi-tab planning sheet

Content briefs cost 25 credits each. The same 100 free credits could instead cover 4 briefs if you want to test that workflow first.

Frequently Asked Questions

Do I need the Chrome extension to cluster from Google Sheets?

No. The extension side panel is the fastest path because you can send highlighted cells straight to a clustering job and paste the results back as TSV. But you can also export your sheet as a CSV (File, Download, Comma-separated values), upload it to Optiwing, and re-import the clustered CSV. Both routes produce the same SERP-backed clusters.

How do the clustered results get back into my sheet?

Optiwing gives you the clustered keywords as TSV, which pastes cleanly into Google Sheets columns, or as a CSV you can import. Each keyword keeps its cluster name, so you paste it into a new column next to your existing data and then sort or filter by cluster.

Can I keep my volume and notes columns?

Yes. Optiwing only needs the keyword column. Your volume, notes, difficulty, and any other columns stay in the sheet. You add the returned cluster label as a new column alongside them.

How much does it cost?

1 credit per keyword. Your first 100 keywords are free with signup credits. After that, 1,000 keywords cost $10 and 5,000 cost $35 as one-time packs, or $20 per month on the Starter subscription. Credits you purchase never expire.

Why not just use a formula or add-on to cluster in Sheets?

Formulas can group by matching words, but shared words do not mean shared intent. 'Apple pie recipe' and 'apple stock price' share a word and nothing else. Optiwing groups by the actual Google results each keyword returns, which is the signal that decides whether one page can rank for both.

Is there a limit on how many keywords I can send?

There is no per-job keyword cap. The CSV upload path supports files up to 100MB, which covers hundreds of thousands of rows. For very large sheets, cluster in batches so the results are easy to paste back tab by tab.
