Ahrefs lets you check search volume for up to 10,000 keywords at once using its Keywords Explorer tool. You can paste your entire list directly into the search bar or upload a file, and the tool returns volume data, keyword difficulty, and other metrics for every term in one report.
Enter Your Keywords in Keywords Explorer
Open Keywords Explorer from the top navigation bar in Ahrefs. Instead of typing a single keyword, click inside the search field and paste your full list. Each keyword needs to be on its own line. If you have a spreadsheet with keywords in a column, copying that column and pasting it directly into the field works perfectly since each cell becomes its own line.
You can also upload a .csv or .txt file instead of pasting. If you go the file route, format it so each keyword sits on its own row with no extra columns, headers, or formatting. A plain text file with one keyword per line is the simplest approach and avoids any parsing issues.
Before you hit search, select your target country from the dropdown next to the search bar. The volume figures Ahrefs returns are country-specific, so make sure you pick the right market. You can also choose a search engine (Google is the default, but Ahrefs supports YouTube, Amazon, Bing, and others depending on your needs).
Reading the Results
After you submit your batch, Keywords Explorer loads a metrics overview and a full keyword list. For each keyword, you get monthly search volume, keyword difficulty (a 0 to 100 score estimating how hard it is to rank on page one), clicks data showing how many of those searches actually result in a click, and cost-per-click estimates if you care about paid search.
The results table is sortable. Click any column header to reorder the list by volume, difficulty, or another metric. This makes it easy to spot the highest-volume terms quickly or isolate low-difficulty opportunities. You can also use the built-in filters to narrow results, for example showing only keywords with volume above 500 and difficulty below 30.
To save or share your results, export the table as a CSV. The export includes all the metric columns visible in your report, so you can pull it into a spreadsheet for further analysis or hand it off to a teammate.
Plan Limits That Affect Your Batch
While Keywords Explorer accepts up to 10,000 keywords per search, your Ahrefs subscription tier controls how many rows actually appear in reports. On the Lite plan, reports cap at 2,500 rows. The Standard plan raises that to 30,000 rows, and the Advanced plan goes up to 75,000. If you paste 10,000 keywords on a Lite plan, you will still get results, but any associated sub-reports (like keyword ideas generated from your list) will be trimmed to the row limit.
For most batch volume lookups where you simply want metrics on the exact keywords you entered, the 10,000-keyword input limit is the binding constraint, not the row cap. The row limit matters more when you use features that expand your list, such as generating related keyword suggestions from your seed terms.
Organizing Large Batches With Keyword Lists
If you regularly work with large keyword sets, Ahrefs lets you save your batch into a keyword list for ongoing tracking. After your results load, select the keywords you want to keep and add them to a new or existing list. These lists live inside your Ahrefs project, so you can revisit them later without re-entering everything.
This is useful when you want to monitor how volume trends shift over time or when you are building out content calendars across multiple categories. You can create separate lists for different topics, product lines, or client projects, then check back monthly to see updated metrics without repeating the batch search.
Using the API for Larger or Automated Batches
If you need to pull keyword volume programmatically or on a recurring schedule, Ahrefs offers an API with Keywords Explorer endpoints. The API lets you request metrics for a single keyword or a list of keywords, including search volume history and volume broken out by country. For batch analysis, each API request handles up to 100 targets at a time, so you would loop through your keyword list in chunks of 100.
The API route makes sense when you are integrating keyword data into internal dashboards, feeding it into a database, or automating reports that run weekly or monthly. For one-off research, the browser-based Keywords Explorer with its 10,000-keyword input is faster and requires no coding.
