Welcome to the Q&A Forum

I'm a bit confused today at Google's SERPs for a number of queries I've done. The first one that sparked my interest is when I searched for 'pinterest' (no quotes) and pinterest.com was NOT on the first page. In fact, the first pinterest.com result was on page 3 and was the page for somebody named Bil Chamberlain, who himself must be more related to the search term pinterest than pinterest.com itself. I've done this for a variety of search terms, signed out of google, signed in, and some companies' home page, or website in general comes up, and some do not. search for facebook, facebook.com is #1 search for united airlines, united.com's "Club and Lounges" page is on SERP 5. Am I missing something in google's search result methodology? I'd love to be directed to some article or discussion related to this because the last time I checked, most brand name or company name queries turned out company or brand home pages as reesult #1. I very well may just be behind the times. CCpjw

We are currently in the process of changing all of our image names and their alt-tags to be descriptive of their content. For instance, changing image names from image0001.jpg to blue-cell-phone-cover. We have hundreds of images on our site, would it be best to rename all of the images and update their tags in one sweeping change or trickle the changes, uploading changed images every other day or so?
