To be precise,
- Title Match or TM provides the number of pages in Google’s Top10 that have adopted exact match in the title — that therefore used exactly the exact keyword or string of keywords in the title.
- Partial Match or PM lets you know how many pages, as a percentage, used the keyword partially or with variations.
Initially present only in the analysis of the advanced URL Inspector tool , these metrics are now present in all Keyword Studio tables. These are values that help determine Keyword Difficulty because they analyze the level of competitiveness of keyword optimization, providing useful information especially for refining evaluations on long tail keywords.
