Paying for Open Access: Most publishers will make your article "open access" for a fee —up to $5,000; so-called "Gold OA". But it still won't be exposed to most search engines, and many non-subscribers will never find it.
"Self"-Archiving for Open Access: Most publishers will allow you to self-archive for free —this also makes your article open access; so-called "Green OA". And Google, GoogleScholar, etc. will index it and send users there.
We also do Original Publications
