webmaster

20+ years ago, I put together web sites honoring those from my hometown area who were killed in the Vietnam War. For about 10 years anyone using search engines could find them easily. With in the last 2 years, the search engines will not carry a search for those sites. I have contacted my web site hosting company several times and they have no idea why search engines are not working on their hosted sites. 

The web sites that I have that are not being picked up anymore are, https://vietnamveteransmemoral.homestead.com/Home.html  http://175thengineers.homestead.com/homepage.html   http://eastonvietnammemorial.homestead.com/Home.html   http://alumniehsn.homestead.com/Home.html   http://321gimlet.homestead.com/Home.html

Can anyone tell me why the search engines are not picking up my web sites and what I must do to have them start doing it again.
