News is that google webmaster would not show keyword impressions and all search would go through google secured search. earlier Google stopped showing related keywords in adwords and not webmasters would not show impressions or searches. With this what should be the new SEO technique for webmasters, rather than shooting in the dark.
It is a disappointment, isn't it? Knowing why people found your site is the key to creating a better site.
There is a way to get some of this data (at least some), which is to use the webmaster tools search queries. You can get up to 3 months of keywords, and they include the secret keywords.
There's also the option of using other third party tools for analytics or integrating your own system that tracks the visitors and monitors their behavior on your website. There are many companies out there that do the same services webmaster tools provided. Some are free, others require payment. But, it's good to know that there are other options. I encourage people not to put all of their time and money into a single company's service, because then you become dependent on them and when changes such as this occur, it can become a tragic event. I say experiment. Another strategy is to actually hold an experiment. Survey visitors and customers and find out more information in regards to their searching habits that way. It's great to get feedback from the visitor themselves instead of having a program tell you everything.
