Explanation of the Google Supplemental Index

This article can show you through the primary reasons why websites get listed on this index, and why few sites are in the supplemental index and getting them out. For those who have a pre existing site, a top possibility is that you could have websites while in the supplemental index, so make use of this as a research, and be sure to follow the methods discussed below.

To begin with, for anyone of you new to this theme. What’s the Additional Directory? Here is the simple answer, Google has 2 indexes, A “Main Index” and the “Supplemental”.

One of many ways to examine that you are considering a supplemental effect on your webpage is by searching on google with the command “info:yourdomain”.


google results with info command


If your website listed when you search with the command “info:”, your site may not be in the supplemental index but this is just a small way to verify. If you see the green text “Supplemental Results” right after the your site listing, then it is confirmed that your site is not the primary. For that, search with the command “site:” followed by your domain name.

Why do pages transfer from main index to supplemental?

There are numerous and some not too obvious reasons for this, but Identical Information and Low-Updated are the two major types. A complex URL, with parameters and variables or pages deep in the site structure also accounts for this. A word of advice on link building: link buying/marketing or linking to spammy sites or performing excessive mutual links can harm your site. Google calculations has trust that is very low in these sites’ inbound links.

Now that you know what this index is, Let’s look at the tactics to get them out of it and make it to the primary listing. I’ll group them in sets since they are co-connected:

1. Your Internal Profile (Content Uniqueness) and Linking. Your sitemap, that will be the essential part of your interior linking, will include links to every one of the pages in your website, plus it should be associated (typically in the footer) out of every page. As well as your site’s overall link page directly influences because this influences the Page Trust.

2. Site and dynamic URLs Structure. Maintain all URLs as “static” as possible. Why moving 3-4 specifics when there is an easier approach? And every page must be 2-3 ticks from the home site, in terms of the website design. Google like websites with the extension ‘.html’ at the end. As they look more static.

If you are using WordPress and want to use ‘.html’ extension, you can do this on settings -> permalinks page. A caution: if your webpages are already in the index, it might affect your rankings. So it has to be done very carefully without affecting the indexed pages.

3. Duplicate Content. All of your meta tags ought to be special. All websites have common elements like navigation, footer, etc. ensure that your site have sufficient special material to offset these components, and that you’re currently supplying quality content too.

Answers to get out of the supplemental listing.

Again, like I stated before, make it simple on Google, and they’ll make it easy you.
