Did your search engine traffic suddenly drop rapidly or are you about to purchase a domain name? it is always wise to check if your domain name has been blacklisted or DE-indexed by Google?
Be informed, there are several other reasons your website traffic could be dropping rapidly but it doesn’t hurt to check if your pages are still being indexed by Google.
How To Check If A Domain is blacklisted by Google
Simply perform a search in Google with “site:domainname.com” i.e. site:wpseer.com
If no results are returned and your pages have already being indexed by Google previously, then there is a pretty good chance that the website has been removed from their index.
If you use this method to check for a new domain, you probably won’t get any result, as there are no posts or pages for Google to index yet.
The best way to keep track of changes or get more information on your domain is to use tools created by Google. In this case the Google Webmaster Tools is your ideal tool.
Google Webmaster tools would show you links to your site, your search queries, site health, 404 not found pages, server errors and many other useful information on your website.
Submitting a sitemap to Google, frequent posts, a claimed Google authorship account are factors that could get your pages indexed faster.
Violating Google Terms of service is the fastest way to get your pages DE-indexed. Engaging in the following practices could lead to your pages getting de-indexed:

Hiding keywords or phrases with the background color technique is just so wrong and Google already knows about this technique. This could easily translate to your pages disappearing from Google search.
Linking To Spammy or malicious pages
Google, Bing and every search engine hates spam. Always check pages you are linking to, even if it is a guest post, check the links to make sure you are not sending your readers to malicious pages.
Once you have been infected with malware or your site is linking to such a page, you are on a ticking clock.
