We are going to address following issues:

• Combine and tumble keyword lists
• Permutation of phrases in a keyword list
• How to cover typo and spelling errors
• Various tools to clean your keyword lists

How to combine and tumble keyword lists together:

Assume you have following 3 keyword lists:

Keyword list group #1:

• keywords
• keyword

Keyword list group #2:

• research
• marketing

Keyword list group #3:

• program
• software
• tool

Use tumble to input to get following keyword phrases:

• keyword marketing program
• keyword marketing software
• keyword marketing tool
• keyword research program
• keyword research software
• keyword research tool
• keywords marketing program
• keywords marketing software
• keywords marketing tool
• keywords research program
• keywords research software
• keywords research tool

Have permutation cover all word orders in all phrases:

Assume you have following keyword phrase in “input”:

• keyword marketing program

The word order tool can permutate above sentence into:

• keyword marketing program
• keyword program marketing
• marketing keyword program
• marketing program keyword
• program keyword marketing
• program marketing keyword

How to take your keyword lists to the next level:

Can you imagine the number of thousands of phrases above two tools can generate for you? Well, we are not done! Do you have customers that found you using spelling and typo errors in their searches? Probably not… But maybe you will soon. Move your keyword list into “input” and get ready to use following 3 tools:

• “Missing space”. Example: “keyword research” adds “keywordresearch”.
• “Missing letter”. Example: “keyword marketing” adds “keyword markeing”, “keyword markting” etc.
• “Switched letter”. Example: “keyword tool” adds e.g. “kewyord tool”, “keywrod tool” etc.

Cleaning and sorting your final keyword list:

Everyone is different, but if you like to have neat keywords lists here are the tools you need:

• Filter on min/max characters/words
• Filter on allow list of characters (to remove illegal)
• Lower case all keyword phrases
• Sort keyword phrases
• Trim for superfluous spaces
• Remove words repeated, e.g. “phrase phrase expansion”
• Remove phrase duplicates, e.g. “research program” and “research program”
• Remove permutations, e.g. “keywords explode” and “explode keywords”

Above is just one of many tools available in A1 Keyword Research. I will showcase more of them in this blog as time permits

My test have roughly consisted of:

• Some hundred thousand (+) search impressions.
• Some hundred thousand (+) content impressions.
• Different campaigns for all products and content / search.
• Split tested low-performing and high-performing ads in all campaigns.
• All ads ran on Google Adwords PPC system.
• All ads were text based, i.e. no images, videos etc.
• All ads were shown on Google search and networks.

The urls I have split tested against each other are:

• www.microsys.dk vs www.microsystools.com
• www.microsys.dk vs www.microsys.eu

The results? They have been clear and consistent across all tests. www.microsys.dk beats both alternatives with roughly 20% higher CTR in average. A side-by-side split test example:

• Ad showing normal url: 2.00% CTR
• Ad showing good looking url: 2.40% CTR

While this may not seem of much, it is an easy way to improve your ad quality across all your campaigns and adgroups. Worth it if you have many campaigns and ads running through Google Adwords / pay per click (PPC) .

It is slightly odd that www.microsys.dk beats www.microsys.eu, but I suspect it is related to .eu domain names still being relatively new.

Now I have just one problem left… Should I change my primary domain to www.microsys.dk ?
