Retroactively add keywords for your existing Octopress posts
At the moment, I am exploring the world of SEO, and so I thought I could start with my blog. I found SEO for Octopress websites that I followed to add keywords and descriptions to this blog.
To fill actual keywords for all my existing posts, I had 2 options :
- edit around 60 posts by hand
- write a script to parse Yaml post descriptions and extract and inject keywords
Sorry, I chose the geeky solution …

| desc "add keywords to posts" | |
| task :add_keywords do | |
| Dir.glob(File.join(File.dirname(__FILE__),"source/_posts/*.markdown")) do |file| | |
| yaml = YAML.load_file(file) | |
| keywords = yaml['categories'] || [] | |
| title = yaml['title'] | |
| keywords += title.scan(/'.*'/).map {|kw| kw.gsub("'",'')} | |
| keywords += title.scan(/\S+[\sv~>]+?\d+\.\d+\.?\d*/) | |
| title = title.gsub(/[\sv~>]+?\d+\.\d+\.?\d*/,'') | |
| title = title.gsub(/['\?:\d\.]/,'') | |
| keywords += title.split() | |
| keywords_hash = {} | |
| keywords.each do |keyword| | |
| keywords_hash[keyword.downcase] = keyword | |
| end | |
| %w(# a an i on of to in my from how for the just best own after full if ~> and with when do does not are et up way first set like be there only can one per).each do |word| | |
| keywords_hash.delete(word) | |
| end | |
| system "sed -i '1 a\ | |
| keywords: \"#{keywords_hash.values.join(', ')}\" | |
| ' #{file}" | |
| end | |
| end |
Just add this code to your toplevel Rakefile, and run bundle exec rake add_keywords and keywords will be added to your existing posts.
