Below are links to the tokens that Google Ads and Microsoft Advertising (Bing) accept. In general, the only one you really require is the keyword token. These are added to your t202kw= from your generated link in step 8. The other tokens, if you choose to use them, must be assigned to other variables. Generally if you have additional tracking you want to do, we recommend c1-c4.
Google Ads keyword token: {keyword}. Put it right after t202kw= in your link: t202kw={keyword}.
