7. Delete Keyword Clutter
You don’t need to have tens of thousands or even hundreds of thousands of keywords in your account! Sure, a few years ago you needed to make sure you hit on every variation of a keyword term, including the misspellings, plurals, stemmings, accents, etc. However, Google pretty much killed off the Exact and Phrase keyword match types in AdWords last year.
Trying to maintain an account with over 98% junk keywords is just insane. You’re making campaign management and reporting more difficult and weighing down your account. Cut loose and get rid of the underperformers after each round of testing.
6. Delete Useless Ads
Why are you trying to maintain all of these non-performing AdWords ads? It makes your account way more complex and intimidating than it needs to be. AdWords is definitely a game of quality over quantity; in fact, you really need only one awesome ad for PPC success.
Instead of trying to be everything to everyone with hundreds or thousands of ads, use Dynamic Keyword Insertion instead. DKI replaces specific words in your ad with terms that match exactly what the searcher was looking for.
