Archive.org maintains historical versions of sites that allow archiving. You can see how a website looked last year or in 2001. The wayback machine keeps almost all historical versions of your site in its archive.
To many people, Archive.org is just another repository like Google’s index that stores historical data in their timeline. Many Webmasters and Search Engine Optimizers (SEOs) fail to recognize this free feature as an effective SEO Tool. Well, for those non-believers, here are 5 compelling reasons for them to admit that the Wayback Machine is a very useful SEO Tool:
Reason-1: Powerful Tool for SEO Diagnosis
Archive.org’s Wayback machine can be used as a great tool for SEO diagnosis. Have you experienced a recent fall in traffic after updating a site? You and your webmaster can’t tell what happened to the site, and what codes you may have changed, since they were not tracked.
With the Wayback Machine, you can go back and have a look at the code in previous versions of the site, before you made the update. Using a simple code comparison tool like WinMerge will allow you to see the changes in codes side by side. By looking at the changes in code, you can easily diagnose SEO for your site.
Reason-2: Site and Link Aging
Old links are like a fine aged wine in SEO, and helpful in obtaining Search Engine rankings. After changing a site to new Content Management System (CMS), you might create a lot of new links, but forget about the old links. I have seen many webmasters forget about the old links and suddenly web sales start dropping.
You can search for old links through the Wayback Machine and manage the aging of the links in the current site through 301 Permanent Redirects, which is very Search Engine Friendly. Here is a nice article on how you can improve SEO from old links.
Reason-3: Fixing Old Broken Links
As you site evolve, you throw away old links. But, there may be many sites and bookmarks out there that had a link to your old link. Not having the link there or having a 404 page instead, is a very disappointing thing for both visitors and search engines.
You can use the Wayback Machine to track back the old links and hunt down the broken links though Xenu’s Link Sleuth software. This will ensure visitor friendly, smooth browsing from other sites or bookmarks. And the Search Engines will love your site for that.
Reason-4: Source of Unique Contents
Previously, Content was King. However, after the Duplicate Content Filter update by Google, Unique Content became King. As you have probably had different content over the existence of the site, chances are you have created unique content most of the time. Moreover, to keep the site always fresh with content, many webmasters and site owners do this to get the SEO benefits.
If you are doing that, then you can use your old content elsewhere and build inbound links for your site. The best way to find your old content is through Archive.org’s Wayback Machine.
Reasong-5: Evidence for Claiming Copyright
Many people believe that you need to apply for copyright. But, the fact is you don’t need it. Rather, you need a good and strong evidence to claim for your rights. Your archived page in the Wayback Machine may not be a very strong evidence, but it is really a good one.
