The Ajax-Crawling method is a way by which Google and several other search engines spider websites that offer dynamically generated content through scripts called 'ajax'. Google has been using this method since 2021. But on October 15th, 2021, Google officially stated that this method is now no longer recommended and considered obsolete (unchanged). This means that a new algorithm was implemented to determine which web pages are not relevant for the keywords searched by a user. In a nutshell, the algorithm determines the relevance of a web page based on how many times it has been accessed and the keywords used in searching. When this happens, your ajax-crawling strategy is worthless! Google states: "In addition to decreasing the frequency of your site being listed, we've been able to reduce the effect of your ajax code on search engine rankings. We'll continue to evaluate the impact of this change, but in the mean time we will focus on the benefits of our new approach."
As earlier mentioned, one of the main advantages of Ajax lies in its ability to provide a highly flexible means of data transfer. In simple terms, Ajax allows web applications to efficiently communicate large amounts of data without the use of traditional XML document languages. Traditionally, when an XML document was needed for data exchange, it would be translated and then compiled before being used. This translation process consumes memory and slows down the response time of the application. As a result, when large amounts of data are exchanged, the application may take longer to retrieve the updated information. Through the use of XML Hypertext Transfer Protocol (XML), a web application can establish an interface that allows users to send and receive data in a safe and convenient manner. XML provides several different methods of encoding. One of these is a standard XML format, which allows data to be sent in the form of an array. There are other forms of XML available, including XML Web Service (XMLws) and XMLBite. These two different forms of XML are different from each other and although both provide a high level of functionality, they have different pros and cons.
This is the main problem with Ajax crawling. As already stated, Google has already implemented a new algorithm to determine the ranking of websites. This algorithm is different from the one used for traditional crawling. Google states: "Ajax-Crawling methods generally take longer to scan large sites and can lead to false-positive results and, in some cases, incorrect URLs. Our crawlers now access sites in more thorough ways that are more appropriate for searching." The algorithm used by Google is called the heads-only and headless browser method. It is very different from traditional ajax crawling where the actual ajax server is not used. In the headless browsers approach, Google simulates a web browser that responds differently to a keyword query. Google's definition states: "The Googlebot recognizes HTML text that is not a hyperlink and can follow this text without traversing any pages or redirects." In other words, Google's Ajax crawler follows the link as it passes through the web page. The difference between this algorithm and the traditional algorithm is that the ajax crawler does not follow the link; it simply follows the words. Since Google has already eliminated the use of servers to render the ajax crawling algorithm, webmasters need to find a solution for how they will continue to render Ajax links in their websites. They no longer need to load their web pages with Ajax scripts or wait for them to load on their own. Webmasters can set a maximum ajax load time and a maximum ajax execution time so that they do not exceed this time limit. Also, webmasters can avoid the issue of cross-site scripting, which can lead to security issues on the web. Using a cache is also recommended because it will reduce the need to send a new Ajax request for each ajax page that is already loaded. This will reduce the time it takes to read all the pages in a web page. This will significantly reduce the time it takes to complete an Ajax crawling operation. Another option for reducing the amount of ajax crawling time is to pre-fetch the pages before an Ajax request is made by the Google crawler.
There are some advantages of pre rendering Ajax web pages prior to rendering them.
So, if you want to improve your blog posts and make money from them, then you should consider using an Ajax crawling scheme.
If you are an expert in Ajax, you should be aware of the benefits of using a Crawl Indexing and/or Ajax SEO. The difference between these two is that, with a Crawl Indexing, your site will be indexed within the major search engines (Google, Yahoo, Bing) immediately. If you are doing any form of online business, being ranked highly for a word or phrase means business. So, how does this work? Basically, crawlers, bots and spiders, crawl your site to gather data on how the internet user would "type" a keyword or phrase into the browser. It then creates an index of these pages, which are then returned to the client/developer. In a nutshell, Ajax is a group of web development frameworks used to build highly dynamic web applications. A relatively new term, "Ajax" first came about in the late nineties. The actual inventor of Ajax is Mike Proctor. His early efforts included creating a language and application programming interface for the UNIX operating system, to create "web page generators", and" Ajax chat rooms". Today, Ajax is a shortened way to say "Web- Authentication and Encryption". The primary goal of Ajax is to provide a better way for search engines to evaluate a page's importance, by quickly identifying whether it has been optimized for search engines, and whether it contains relevant content.
