Value:
'Special characters in URL' refer to special symbols such as '()*[]'
Recommendation:
It is recomended to avoid special characters in your web site's domain name and
all page names used through your site. Using them can cause several problems with
various search engines when trying to index your site.
Tip #1:
While most non-alphanumeric characters are considered 'special', the dash symbol
(-) is useful for splitting up keywords in your domain and page names. This is because
keywords seperated by a dash are given more importance than keywords with no dash
between them.
