DNSBL Blacklist Check
It’s necessary for webmasters and SEOs to periodically check if their websites are ‘clean.' This implies using a blacklist lookup tool to make sure the website has not been blacklisted. A blacklist in the internet world means that a website is suspected of distributing malware or spam emails. Spam and malware filters identify these sites, and any outgoing content from them is either blocked, or the email is placed in the recipient’s spam mail.
It’s estimated that eighty percent of emails that are generated and sent across the internet are spam emails. Hackers are relentlessly trying to break into sites that contain sensitive information. Once discovered, the sites that they have used to conduct these break-ins are blacklisted.
Yes, domain age plays an important role in Google ranking. Google examines the date a domain got registered and crawling started. How many links are established with other websites? Such authority and relevance are not easy to gain in the internet world. Every website needs to age and displays its importance and relevance before Google, or other search engines will index and rank it.
For example, a new newspaper starts its business and sets up its website. It won't get accolades and recognition straight away. It takes the time to establish any business. Similarly, it takes the time to build a business and a website.
Google and other search engines discover thousands of websites appearing every day across the internet. Search engines conduct a domain registration date checker to keep track of a domain's age as any new business takes the time to get customers and establish itself in the market. Similarly, websites take the time to generate traffic and build their credibility on the internet.
Domain age does not refer to how long you have owned a domain name. You could have purchased a domain name ten years ago and 'parked' it. This means that you own a domain name since ten years but have just been renewing its registration. It's like buying a car and leaving it parked in the garage. Once you start driving it on roads, it will get noticed. Similarly only when a domain becomes active on the internet that Google and other search engines take notice of it and index it. In other words, a domain that’s been registered ten years ago and has no website up will be treated the same as a brand new website that got registered yesterday and became active.
Matt Cutts, a known blogger, and authority on SEO says that young websites will struggle to rank, and clarifies that new websites are small therefore they differ from older websites. However, he goes on to say that after a couple of months after a website has aged and established its place on the internet, it will be competing equally with older and established websites.
Older websites will have an edge as they have more backlinks as they have taken the time to acquire them. They are on search engines ranking and have established their credibility.
Websites that distribute viruses and worms affect the performance of computers on the internet get blacklisted. Hackers and nefarious people are always trying to gain easy access to computers hooked up to the internet, and once they get entry, they spread a worm or virus that can virtually destroy the computer’s software applications.
Some hackers are smart and don’t spread their evil from a single site. They invade a site and use it to spread malware. It makes it quite difficult for spam and malware filters to track the originator. Search browsers and filters keep a constant watch and any system detected of spreading malware gets blacklisted.
There can be several reasons for business websites getting blacklisted.
- If your mail servers are pumping out an unusually high volume of mail.
- If your server is relaying spam mail.
- If spam filter sites detect a high ‘bounce rate.'
- If your emails are graphic and flash animation heavy
- If your email attachments contain malware.
Asides from these there are other reasons for a business site getting blocked. You may be using web applications that contain malware, your site may be infected and is being used to spread malware. If you are using a shared domain hosting service, the hosting service may be blacklisted. This means all sites sharing the services would automatically get blacklisted.
Web hosting servers might not be having updated firewalls in place which allows websites to get exposed to hackers and spam attacks. Hackers and spammers are always sniffing websites and testing their securities. Once they break in they can steal all personal information and misuse it.
When internet authorities like Google, Bing, Norton Safe Web, McAfee SiteAdvisor etc detect irregularities on a website they issue warnings to users who want to reach that site. Each search engine issues a different set of warnings of sites that contain malware, phishing sites or may issue a message that the site has been hacked.
If you get a warning from the browser that you are using, it’s best to steer clear of that website. Infected and blacklisted sites have been sidelined for a reason and it’s best to stay away from them.
Website masters and SEOs should conduct blacklist lookup regularly of the sites that they are managing. To do a blacklist lookup go the searchenginereports.net and click on ‘Free SEO Tools’ icon. Scroll down the list till you come to Blacklist lookup icon. Enter the website’s URL and click ‘Lookup’. This tool will check through all the blacklist lists to see whether the entered website exists on any of the lists or not.
After the test is run the website domain name, IP Address and the overall status will be displayed. If the site is clean the overall status will show ‘Not Listed’. Following this display will be listed the spam database servers on which the test was conducted.
Conducting this blacklist lookup test periodically is a must for webmasters. Websites can inadvertently end up on a blacklist, which will affect the website’s organic traffic. If a website gets blacklisted the webmaster or whoever is responsible for managing the website should take the necessary measures to get the site removed from the blacklist.
Smart phones and tablets are extensive users of the internet and users are warned to conduct blacklist lookup before opening a site. The browser may not issue a warning and it’s up to the user to ensure that the site to be visited is clean and safe. Apple phone users can run blacklist check IPhone. Users can also run Google blacklist check, as Google is a known authority.
Internet users and website owners must take precautions to protect the equipment (desktops. Servers, laptops, tablets, and smartphones) they are using on the internet. Downloading and installing anti-virus is a must for all, users. In fact that should be the first step you take right after you get onto the internet.
Website owners should ensure that the hosting service provider has installed hardware and software protective measures to ensure sites don’t get invaded and blacklisted. Check the protection measures of a hosting service provider before you utilize their services.
