I have a product review website that has been given me average of $$$$ for the past 3 months. The website got ranked for some of the review products. The main one (which I am really concerned about) has average ranking 4 for the past 4-5 months. 7-10 days ago, I notice it went off the search result for the main keyword, when I do the direct URL search e.g. domain.com/product-review-url, I notice that it shown "A description for this result is not available because of this site's robots.txt ? learn more" I checked my wordpress settings if I had blocked the search engine from crawling the website, I checked the google webmaster as well, check the robot.txt but no such thing were blocked and no error or fault anywhere. I go back to the product review post to re-write the description in All-In-One-SEO. After 3 days the description shows up when I check the product url in google search but up till now the URL has not been ranked for that keyword BUT I notice the main domain ranked on the second page (17-21) for that keyword. Please I need help and tips on the way out. I will appreciate every inputs here to get me out of this trouble water as this is the only website that is being putting some money on my table.
