Keyword mapping is deciding on which page on your website will be used for each target keyword so that you can optimize the pages for those target keywords and start link building. It is best practice that you group similar keywords together and build one page for each niche rather than building a new page for every keyword you have. A keyword niche is a group of keywords that all contain the same keyword such as – funny desktop wallpapers, cartoon desktop wallpapers, beautiful desktop wallpapers, blue desktop wallpapers, etc. Keyword mapping can be done in spreadsheet software such as Microsoft Excel.
You should also add the URL structure you plan on using for each group. Going back to the desktop wallpapers example, you might want to use the URL structure: /desktop-wallpapers/ for that niche.
