  2. 2. Lots of webmasters complain about some sort of hosting issues even if they are using the bestavailable web server. It affects the performance of their websites. More importantly it can leadto websites getting lower in search engine ranking. Diagnosing these problems is not easy. Youcan’t do much if you don’t know if there is any problem.Following are some of the most important problems associated with web hosting withguidelines to fix them: 1. Blocking of search engine crawlers: Your website is perfectly search engine optimized. All contents are informative, unique and authoritative. Suddenly, search engine stopped crawling of your website. Many webmasters complain about this problem. The obvious solution is to submit content, use ‘Fetch as Googlebot’ feature of Google Webmaster Tools, and submit XML sitemaps. But, since it is a hosting issue, your website will not be crawled. The main problem is misconfiguration of DoS protection system and firewall.Sometimes it also occurs due to a problem in the Content Management System (CMS) awebsite is using. Protection system along with perfect firewall installation is necessary. It helpsin blocking high level of suspicious server requests which is a sign of hacking attempt. Moreoften than not, Googlebot also accesses a website quite with increased frequency. It dependson many factors, but it makes protection system employed at the web server to blockGooglebot and not allow it to crawl your website.You can easily diagnose this problem. Use ‘Fetch as Googlebot’ in your Google WebmasterTools. Submit content for indexing and you will get the response. You can also use ‘Crawl Error’section of Webmaster Tools to get the answer. Contact your web hosting service provider andask for immediate help. In the meantime, you are also required to configure URL parametersfor easy crawling and indexing.
  3. 3. 2. Issues of Availability: Search Engine crawlers have visited your website. But what if it isunavailable like 404 errors or other reasons? A few attempts and crawlers will decrease thefrequency of accessing your website. There might be many problems behind the ‘unavailablesignal’ of a website like overloaded servers that leads to refused connections and timeouts,DNS issues, misconfiguration in the Content Distribution Networks (CDN), etc. You can findthese issues in Google Webmaster Tools or Bing Webmaster Tools under Crawl Error section.Whatever might be the type of your web hosting service like shared, VPS, or dedicated, thisproblem can happen.3. Invalid SSL Certificate: The SSL certificate can only be valid when it matches with the name ofyour website. You might have encountered many SSL errors thrown out by web browsers. Somecommon problems related to it are expired SSL certificates as well as misconfigured servers. Itcan happen more with shared hosting environment where a small error can lead to all sharedwebsites using the same certificate. Google will inform you, through webmaster tools, aboutthe existence of any such error. You need to act immediately and contact the technical supportof the hosting company for appropriate solutions. Make sure SSL certificate being used for yourwebsite is valid.4. Wildcard DNS: You can easily configure your website to clearly respond to all types ofsubdomain requests. For example, a website, say, can be configured to respondto requests to,, etc. In most of circumstances it isperfectly desirable to have this type of response system. However it can lead to seriousproblems of web access if a subdomain is not available. To eliminate any possibility of this errorrelated to wildcard DNS setups, you need to configure the website to just avoid them. You canalso configure the web server to just avoid responding to non-existent hostname. It can bedone easily by refusing the connection. You can also do it by configuring the HTTP 404 header.5. Misconfigured Virtual Hosting: Sometimes multiple hosts or domains that are hosted on thesame server returns contents from only one website. It is quite tedious problems. The server ishosting multiple website, but it is returning content from only one. Whatever the request mightbe, the content will be returned from only one website. You are required to keep checking thatthe web server is responding correctly or not to the HTTP header of the Host. To avoid thisproblem, you need to consider hosting your website on dedicated server.These are some of the most common problems faced by webmasters around the world.Understanding these problems can lead to better management of your website and moreoveryou can avoid any loss of search engine ranking.
