Determining the keywords your consumer will type into search engines is difficult to predict. That is why there are six easy steps to make the process easier for your next campaign.
Step 1) Brainstorm! The most obvious step is to come up with a list of potential keywords that your consumers would type into Google or Bing and come to mind when thinking about your brand or product.
Step 2) Examine your marketing collateral: This step involves looking through your past marketing channels and communications to see keywords that you used previously and were successful with. This also gives ideas as to what keywords your consumer has seen about your brand.
Step 3) Focus on horizontal and vertical expansion using third-party tools: Here you focus on expanding your search by examining the keywords that other third parties, businesses and search engines are using or are most popular. This information can give you more ideas and potential options that you may have not considered on your own. However, do not solely rely on third party suggestions because they can be either incomplete, misleading or expensive.
Step 4) Multiply the keyword list with synonyms and alternatives: This step entails analyzing your generated keyword list and looking at words that are similar or slight variations to the original word. Doing this gives you other possible options to use and expands the possibilities.
Step 5) Remove duplicates: Looking at your large list of keywords, it is time to go through the list and take out any repeated keywords.
Step 6) Remove keywords that are clearly a poor match for your website: Once you have removed the duplicates and developed a list of potential keywords to use, you then examine the list once more to determine words that would not fit with your brand or website. Your final list should include a specific set of keywords that are relevant and applicable to your campaign.
