If two keywords differ by one word, a negative keyword is added to one of them. Examples: #| || **Original keywords** | **Result** | **Comment** || || _Trip to mars_ _free trip to mars_ | _trip to mars -free_ _free trip to mars_ | ![](../_assets/button-ok.png)Negative keyword added || || _buy trip_ _buy trip alpha centauri_ | _buy trip_ _buy trip alpha centauri_ | ![](../_assets/button-cancel.png)Keywords differ by more than one keyword, overlaps are not eliminated || || _moon tour -reviews_ _book tour to Moon_ | _moon tour -reviews -book_ _book tour to Moon_ | ![](../_assets/button-ok.png) Negative keyword added Word order, grammatical form, and stop words do not matter || |# #### **Merge duplicates**   Combines several phrases that differ only in negative keywords. The combined keyword will contain the negative keywords from all the original keywords. The other keywords are deleted. If statistics exists for keywords, the keyword with the best CTR is left. Examples: #| || **Original keywords** | **Result** | **Comment** || || _flight to the moon -cartoon_ _moon flight -free -cheap_ | _moon flight -free -cheap -cartoon_ | ![](../_assets/button-ok.png) The keywords have been merged. Word order, grammatical form, and stop words do not matter || || _flight to mars_ _fly to mars_ | _flight to mars_ _fly to mars_ | ![](../_assets/button-cancel.png)Different parts of speech, no merging || |# You can also optimize a set of keywords that belong to different ad groups or campaigns.
