While working on a client site which is based on deals and offers I found that whenever I am using % sign in the title of the post, it gets removed from permalink.
After doing some research, I found that wordpress removes it automatically to make the URL search friendly. Some people suggested using "percentage" instead of % sign. I believe that using percent word on a deals website is quite awkward.
Is there is any other way to make it possible to use % sign without damaging the SEO of the website? Do you guys think that if I use % sign in the title and permalink removes it, then it will hurt the SEO?
Many PHP websites (not wordpress) which are already using % sign are doing great in Search rankings. How are they making it possible?
