My web address is: http://www.mostoriginal.com/Kabbalah/ In the past 5 years the meta description in the page wasn't change. This is e-commerce website and in the past days google add the line of "Products X - Y of Z" to the description at the search reulsts. I didn't change anything at the website, this change happened in all the categories of the site. How can I drop the line of "Products X - Y of Z"? As you can see it isn't shown on the meta description at the source code... How can I driop this line in the search results? Thanks.
Did you checked in Google webmasters tool for any errors? I think you've used same meta-description for different pages and also the description looks small.
what do you mean by drop on google? if you mean by updating indexing page. they i would suggest you for go with pinging your site on social bookmarking sites. It will help you to index your updates meta text on google.
Just change the meta description again, problem solved! Be sure to check that this not happens again.
