Keyword Optimizer Tool
v1.0.1Cleans and reformats keyword lists from a pasted block or uploaded text file. Operations include dedupe, lowercase, sort (alphabetical, length, or frequency, ascending or descending), strip common words or single letters, preserve numbers and phrases, exclude ASINs, replace one term with another, and remove rows by starting characters or containing substrings. Output is wrappable per term (e.g., quotes for phrase match) and joined by a custom separator.

Documentation
The keyword optimizer tool cleans and reformats keyword lists for SEO, PPC, and content marketing work, turning a messy pasted or uploaded list into a properly deduplicated, cased, and sorted set ready for upload to Google Ads, Amazon backend search terms, or an editorial calendar. It handles the mechanical cleanup a spreadsheet would otherwise take by hand: removing duplicates, normalizing case, and formatting terms into the exact structure a given platform expects.
Messy keyword data from multiple sources cleans up in one pass: duplicates drop, special characters strip out, and case normalizes to lowercase for consistent naming. Sorting by alphabet, length, or frequency surfaces long-tail opportunities and high-value themes. Protecting numbers and preserving phrases keeps product codes and long-tail intent intact, and excluding patterns such as ASINs removes marketplace noise that has no place in a keyword set. Wrapping terms for exact or phrase match, with a custom separator for the output, prepares a list for direct upload.
- Deduplication and case normalization for consistent campaign structure.
- Sorting by alphabet, term length, or frequency to prioritize targets.
- Removal of special characters, single letters, or common stop words when needed.
- Number protection and phrase preservation to maintain product codes and long-tail intent.
- Term replacement, exclusion of phrases containing specific words, and removal of words by starting characters.
- Wrapping for exact or phrase match with a custom separator for export.
- Automatic exclusion of ASINs from marketplace data.
- Frequency counts to validate search themes and detect overuse.
A pasted or uploaded keyword list (.txt) runs through deduplication, lowercasing, and special-character cleanup, then through any filters set to replace terms, exclude phrases, or add prefixes and suffixes to each keyword. A sort mode, alphabetical, length, or frequency, in ascending or descending order, orders the result. Wrapping prepares exact or phrase match sets, and a custom separator formats the list for bulk upload before it is copied or saved.
- Google Ads Keyword Prep: Keyword phrases split into individual terms, cleaned of special characters, and formatted for ad group targeting.
- Amazon Listing Optimization: Deduplicated, lowercased, comma-free output forms a clean backend keyword string for a product listing.
- Bulk SEO Keyword Cleanup: Thousands of keywords from research tools reduce to high-value or long-tail terms once common or single words filter out.
- Content Planning: Keyword ideas sorted by length or frequency show which terms are worth targeting in blog posts or landing pages.
- Competitor Keyword Analysis: Scraped keyword data cleaned of noise highlights the strategic opportunities underneath.
- Google Ads Keyword Matching: The wrap-keywords feature formats terms for match types, quotes for phrase match, square brackets for exact match, with a separator such as newline or comma for bulk upload or tagging. For example:
dog toybecomes"dog toy"(phrase match)blue chew toybecomes[blue chew toy](exact match)-cat toybecomes-"cat toy"(negative phrase match)
A phrase-match set wraps terms with quotes and separates them with new lines for quick upload. An exact-match list wraps with brackets and exports with commas for CSV pasting. Marketplace data cleaned of ASINs and single letters, then sorted by length, surfaces long-tail targets for informational posts. Replacing repeated misspellings with a corrected term, preserving numerical specs, and adding a consistent suffix such as "for small dogs" tailors product variations to a specific listing.
The output panel gives the final keyword list, total characters, and word count. Frequency counts identify repeated search themes and near duplicates worth consolidating. Wrapping and separators should match the upload format a given ad platform or CMS requires, and filters and sorting can be adjusted until the list matches the intended campaign structure.
How accurate is frequency counting? Frequency reflects exact string matches in the input and helps identify repeated terms. Can numbers such as sizes or model IDs be kept? Yes. Protect numbers retains product codes and measurements. Which match types can be prepared? Phrase match uses quotes and exact match uses brackets. How is a useful word kept from being removed? Disabling stop-word removal or preserving phrases keeps precise intent. How should the result be exported? Copy suits a quick paste into an ads editor; Save downloads a text file suited to spreadsheets and bulk imports.
