WebSite-Watcher's keyword feature supports two possibilities:
Highlight specified words in a page
Get a notification only, if specified keywords are available within new/changed content
Both features work independently. If you want to highlight the same keywords you're looking for, then you have to enter the keywords twice, to the update-on-keyword list and to the highlight-keyword list.
Open the bookmark properties
Select the Keywords tab
Enter the keywords which should be highlighted. Enter one word (or phrase) per line.
Enter the keywords for which you would get an update notification. Enter one word (or phrase) per line.
Note: Keywords are only highlighted in the version with highlighted changes, not within the new/old version of the page.
Please note, that the new version will only be saved when at least one of the entered keywords is found in changed content.
