Last week we reported that Google Webmaster Central Showing Back Link Anchor Text. But when I checked some of my other sites in Google Webmaster Central, I noticed the anchor text report was missing, even from verified sites.
Vanessa Fox of Google Webmaster Central posted in the WebmasterWorld thread telling us that Google is "working to make the anchor text phrases available for more sites, so if you don't see this data now, you should hopefully see it in the coming weeks."
In addition, she also informed us that both the anchor text reports and link reports will be updated monthly.
we update both links data and anchor text once a month
Finally, Google may also bring back the single keyword anchor text reports, for those who miss it.
