One of my websites recently took a major dive in rankings on an important keyword search: 'queenstown wine tours'
And yet it still ranks highly on: 'queenstown wine' which is less specific. The only recent change was to have a google sitemap created.
The website is www.appellationcentral.co.nz
I have waited a few weeks to see if it improved but nothing has changed. Secondary pages still rank in the top 20 but the index page seems to have disappeared down the rankings.
Can some please offer some advise.
