Each ad group has a limit of 2,000 keywords. To ensure that accounts do not place unnecessary load on our advertising servers, we ask that you keep the overall number of keywords in your account to a manageable size (typically 50,000 keywords or less). When you approach an unmanageable amount of active keywords, we'll place a notice within your account and request that you refine your keyword list and remove unnecessary keywords. In most cases, a handful of well-targeted keywords will deliver the majority of your relevant clicks and there is no need to create hundreds or thousands of keywords.
By default, our ad system does the work for you by displaying your ad on variations of your keywords, including misspellings and similar keywords. This means that one keyword can serve the purpose of several related words or variations. Adding the additional variations separately will not necessarily increase your visibility by much. Regardless of whether or not your account contains a small or large number of keywords, you can always take advantage of a 'well-scrubbed' keyword list that focuses on your most targeted keywords. We recommend that you build your keyword lists with the following in mind: Do ...- Use our keyword matching options.
- Use our Keyword Tool to select your keywords and see which related searches will trigger your ads.
- Review our FAQ on making your keywords work for you.
- Include these variations: misspellings (french cusine), capitalisation (French cuisine), incorrect spacing (french cui sine), hyphens (french-cuisine).
- Use variations that are more than three words in length·(best for unique markets and product names).
- Use a three-word keyword in multiple matching variations at one time: [buy red bicycle], "buy red bicycle", buy red bicycle.
