As discussed, it is pretty tough for Google to crawl the webpages that are written in JS codes. The crawling process is all about new discoveries and the process is complicated. It uses web crawlers or spiders to accomplish the function. Googlebot is one of such popular crawlers that treat websites like 301 pages from the indexing standpoint. Such indexed URLs are replaced by the redirected URLs.
Googlebot identifies the web pages and follows the links in the pages until the point where the web pages get indexed. This is accomplished by using a parsing module, which does not render pages but only analyzes the source code and extracts the URLs found in the script. These web spiders are able to validate the HTML codes and the hyperlinks as well. Googlebot can be helped by informing which pages to crawl and which not to follow as well by using a robots.txt file.
By this method, the crawler gains access to the code data of the web page. The robots.txt file can be used to instruct Google on which pages we want our user to see and which, not to gain access to. The same file can be used to avoid ranking drops and errors and to enhance the speed of bots too.
Robots.txt file offers enough crawling opportunities for search engines and blocking them would make the page appear different for web crawlers. Thus, search engines cannot gain complete user experience and Google may consider such actions as cloaking. It is important to render all the resources for web crawlers to see the web pages in the same manner as that of the users.
This is a strong SEO tool to build the architecture of the website and project some important web pages to the Search engines. These internal links should not be replaced with JS on-clicks. Internal links can be built with regular HTML or DOM tags for better user experience.
JS websites include fragment identifies with their URLs such as hashbangs and lone hashes which are strictly not acceptable by Google. It is recommended to use APIs as they update the URL in the address bar and allows the JS websites to leverage clear URLs. A clear URL is search engine friendly as it is understood even by non-technical users.
Though Google is able to crawl many forms of JS web pages, some of them seem more challenging than others. Thus it is important to test the website to predict possible problems and mistakes and to avoid them. It is important to check if the content on the webpage appears in the DOM. Few web pages should be checked to ensure if Google is able to index the content.
Google still supports HTML snapshots, though it suggests these as elements to be avoided. These will be important at instances if the Search engines are not able to grasp the JS on the website. Returning HTML snapshots to search engine web crawlers is better than the content being rejected altogether.
When a browser creates a DOM with HTML document, massive files exist on top of the document and all other information appears later. It is desired to lead information that is crucial for the users first. The most essential information should be on top of the fold to avoid site latency and to make the website SEO friendly.
whatever tech is been used with server rendering, it has to be made sure that a universal approach is used. It also makes it easy to render apt pages for web crawlers to list in search engines.
Most of the website developers tend to improve their performance by incorporating a lot of images. But search engines would rely on the images and render them image specific traffic. For rendering all images, website developers have to use an architecture using jQuery to control what is been shown in the search engines.
There is a tendency with websites to have a single block element that swaps the content in and out, but it also means that content only in the first tab gets indexed and others won’t. Apart from pages in the return polices and privacy statements, other important content of the website should not be framed under this category.
Only the first appearing data in the webpages are indexed and the rest are not. So content on the other pages should also be linked with the URL that is easily resolvable by search engines to link.
Updates with metadata and their routing can be nightmares for JS oriented websites. Solutions such as Vivaldi are fine as it allows prompt metadata creation both in the initial loads and its navigation pages. There is also consistency in user experience to navigate between pages and thus google considers them for ranking.
Pages require an optimum URL along with server-side support for search engine rankings.
It is important to inspect rendered HTML element using SEO practices as that of traditional pages.
It is important to avoid contradictions between HTML versions.
A number of search engine crawlers have difficulty crawling JS based websites and as result brand managers and web developers stop creating web pages in java based platforms. But indeed some of the JS-based websites are excellent with adorable user experience. It is high time that we get SEO work strategically with JS and help website developers and end users take the best advantage of what technology has to offer them.
One of the best practices of pairing SEO and JS is page rendering on Google Search. This is because search engines crawl the rendered pages rather than the source codes. A lot can be missed by considering only the source codes and crawling such rendered pages is time-consuming and provides little value for the information.
Googlebot makes use of a rendering service from the web which is the optimal location to optimize a website. The URL structure is the first interesting thing that attracts crawlers when accessing a page. One best practice of JS SEO is to get the website URL accessible for search engines. JS webpages tend to use a lot of hast tags and anything that is after a hashtag is not sent to the server and identified by Google. The best alternative for this is hashbang that tells Google to consider the URL. One way to enable website crawlers to track the URL is to use clean URLs with webpages and leverage on the push State function of the website API.
Using internal links that can be crawled and followed by the search engines is also a good practice. Internal linking throughout the website will help in the best SEO practices and also gives an opportunity to promote the content of the web.
Speeding up the content load times is an efficient SEO practice in JS pages. Metadata is the best tactics here as it offers a lot of information in a particular location of the site and also facilitates excellent navigation. Tabbed content may also be used to speed up load times. The content on the second, third and the fourth tab can keep loading while the user is still navigating the first tab. But when google lands on those pages where the content is hidden then it will escape from search crawlers. Thus the best practice is to create independent pages for each of those tabs.
For business success, the websites have to ensure that the audience is able to access and read the content. For easy accessibility, Google has to rank the pages on top of the search engines. There is ample technology to ensure that the website looks great. But if the search engines will not be able to access that content, then web visibility will drop too many folds. Thus, SEO needs to work and adapt to the limitations of technology so as to enhance visibility and traffic for business profitability.
