My Wordpress website has local news and information on the town in Spain that I live in. The main news page gets updated every day (and sometimes several times a day). Google indexes the new news stories pretty much instantly (which are individual posts on the site), but only indexes the main news page (which shows summaries of the news posts) every week or so.
For example, if you type Nerja News into google (UK) we are number 5 on the results and it says
"6 days ago – NERJA NEWS - Updated Today - Local news, Whats On Now Guide, Weather and accommodation for Nerja and the surrounding area, plus"
If you type one of the news stories into google in quotes, eg "Nerja council´s Department of Popular Traditions have announced that registrations are open for the San Isidro" the page comes up on google within minutes of it being posted.
So my question is, how can I get google to index my main news page more frequently, as obviously if it says "6 days ago" it doesn't look like it has been updated for a week. Have I missed something obvious?
My news page is http://mynerja.com/about/nerja-news/
Any suggestions welcome as I am stumped at the moment.
