The Robots Exclusion Protocol (REP) is not exactly a complicated protocol and its uses are fairly limited, and thus it’s usually given short shrift by SEOs. Yet there’s a lot more to it than you might think. Robots.txt has been with us for over 14 years, but how many of us knew that in addition to the disallow directive there’s a noindex directive that Googlebot obeys? That noindexed pages don’t end up in the index but disallowed pages do, and the latter can show up in the search results (albeit with less information since the spiders can’t see the page content)? That disallowed pages still accumulate PageRank? That robots.txt can accept a limited form of pattern matching? That, because of that last feature, you can selectively disallow not just directories but also particular filetypes (well, file extensions to be more exact)? That a robots.txt disallowed page can’t be accessed by the spiders, so they can’t read and obey a meta robots tag … [Read more...] about A Deeper Look At Robots.txt

Understanding the difference between the robots.txt file and Robots Tag is critical for search engine optimization and security. It can have a profound impact on the privacy of your website and customers as well. The first thing to know is what robots.txt files and Robots Tags are. Robots.txt Robots.txt is a file you place in your website’s top level directory, the same folder in which a static homepage would go. Inside robots.txt, you can instruct search engines to not crawl content by disallowing file names or directories. There are two parts to a robots.txt directive, the user-agent and one or more disallow instructions. The user-agent specifies one or all Web crawlers or spiders. When we think of Web crawlers we tend to think Google and Bing; however, a spider can come from anywhere, not just search engines, and there are many of them crawling the Internet. Here is a simple robots.txt file telling all Web crawlers that it is okay to spider every page: User-agent: * Disallow: … [Read more...] about Have You Considered Privacy Issues When Using Robots.txt & The Robots Meta Tag?
In the battle between search engines and some mainstream news publishers, ACAP has been lurking for several years. ACAP — the Automated Content Access Protocol — has constantly been positioned by some news executives as a cornerstone to reestablishing the control they feel has been lost over their content. However, the reality is that publishers have more control even without ACAP than is commonly believed by some. In addition, ACAP currently provides no “DRM” or licensing mechanisms over news content. But the system does offer some ideas well worth considering. Below, a look at how it measures up against the current systems for controlling search engines. ACAP started development in 2006 and formally launched a year later with version 1.0 (see ACAP Launches, Robots.txt 2.0 For Blocking Search Engines?). This year, in October, ACAP 1.1 was released and has been installed by over 1,250 publishers worldwide, says the organization, which is backed by the European … [Read more...] about ACAP Versus Robots.txt For Controlling Search Engines
The Robots.txt Summit at Search Engine Strategies New York 2007 was the latest in a series of special sessions with the intent to open a dialog between search engines representatives and web site publishers. Past summits featured discussion on comment spam on blogs, indexing issues and redirects. The subject of this latest summit was to discuss the humble but terribly important robots.txt file. Danny Sullivan moderated, with panelists Keith Hogan, Director of Program Management, Search Technology, Ask.com, Sean Suchter, Director of Yahoo Search Technology, Yahoo Search, Dan Crow, Product Manager, Google and Eytan Seidman, Senior Program Manager Lead, Live Search. The Robots.txt summit session was not on how to use the robots.txt file, rather as Danny Sullivan explained, “We’re assuming you know how to use it and are frustrated with it. This is about how you want to see it evolve.” For a potentially dry and technical subject, the panel turned out to be quite … [Read more...] about Up Close & Personal With Robots.txt
One of the latest webmaster things floating around the web today is on the businesstxt file. It is based on the concept of a robots.txt file but is there to give business owners an easy way to give search engines and local search engines a way to discover the business address(es).Business.txt is a file that local businesses upload to their website with their business information so all website providers can update it whenever something is changed.It is located typically at the root of the domain under a file, /business.txt.Googler, Paul Kinlan, said on Google+ that this is a bad idea. He said:Please don't do this. I get humans.txt, but this is content that should be on your site and discoverable and searchable. The same problems this is trying to solve will also be present in this solution.Yelp and all similar services need to get smarter and do the page scanning and indexing automatically.. THIS WILL NOT SOLVE THAT PROBLEM.There are markup solutions like Schema.org to handle this … [Read more...] about Googler: Don’t Use business.txt Files
