You have to specify a field separator.

sort -n -to -k3 Photos


-to tells sort to use o as the field separator. The numbers are in the third field (the first field contains ph and the second field contains t) so we use -k3. -n tells sort to sort numerically instead of alphabetically.

Sort lines based on a variable-width number at a fixed position
I'm looking at a site for which the domain name and URL do not impart any meaningful data to a search engine.  It does have:


&lt;h1&gt; (eBook name)
&lt;h2&gt; (author - cannot be changed) 
&lt;p&gt; (description)


Do the &lt;h1&gt; and &lt;p&gt; elements provide SEO value?  Those are the only elements in that page that really provide any relevant information to search engines.   I see other sites that use keywords in their URL.

In theory, can the &lt;h1&gt; element be compared to a domain name in terms of SEO value?
