Although not an exact science, the skyscraper technique allows you to extract the common themes and headers of the top performing pages for any given search term.
For example, if you’re a local locksmith and you want to produce content around “emergency locksmith”, complete a search in Google and analyse the top ten results for that keyword.
You can use a tool like URL Profiler to extract all of the headers and analyse them for common themes.
Once you have a list of common headers and topics, create the page plan around those common themes. To improve the page, use the SEMRush keyword magic tool to find related keywords and questions, build out an FAQ section for even better contextual relevance.
