Keyword research for Pinterest usually ends with a long, unsorted list: phrases from the search bar suggestions, Pinterest Trends and your own analytics. Before you can use it, you need to know which keywords belong together, because one board and one set of pins should cover one topic. Sorting a hundred phrases by hand is slow and easy to get wrong.
This grouper does the first pass for you. It finds the words your keywords share, spots the overall theme of the list (such as "fall") and groups each keyword under its most useful shared word, so "fall front porch ideas" and "small front porch fall decor" land together. Every group gets a suggested board name and three pin title ideas. It works on words only and has no search volume data. Bulk mode lets you import the list straight from a CSV or Excel file, such as a Pinterest Trends or Keyword Planner export, instead of pasting it.
How the grouping works
Each keyword is split into words. Common filler such as for, the, easy and ideas is ignored, and simple plurals are matched, so wreath and wreaths count as one word. A word that appears in more than half of the list is treated as the theme rather than a group, so a list of fall keywords is not lumped into one giant fall group.
Every keyword then joins the group of the word it shares with the most other keywords. Broad words such as decor or recipe are used only when nothing more specific is shared, and groups smaller than your minimum fold into a member's next best group or into Other keywords. It is a fast, predictable first pass. Read through the groups and move anything that belongs elsewhere.
From groups to boards and pins
A group with many keywords is a good candidate for its own board, or a board section if it sits inside a larger topic. Keep board names short and searchable; the board name generator gives more options. Smaller groups often work better as a handful of pins on an existing board.
Use each keyword in a pin title and description rather than packing several into one pin. The Pinterest headline analyzer scores your title drafts, and the content calendar helps you spread the pins over the weeks before the season peaks.
