Many webmasters are confused with the advantages and disadvantages in using Javascript to display their RSS feeds. Javascript can be easily used to display RSS feeds on a website. However, some say it is not the most search engine-friendly method available.
PHP coupled with HTML is the preferred method for displaying feeds on a website when it comes to search engine optimization. This is so because servers use the PHP language to communicate with an HTML website. The search engine spiders do not recognize the PHP, but it recognizes the HTML that PHP initiates and controls via the server.
Search spiders are very ancient in regards to recognizing new markup language technology. One could say search engines are lagging so far behind in terms of markup language interpretation that it is surprising that they still manage to continue functioning. They continue to function because HTML is still the main language used by websites.
On the other hand, search engines have made great strides in recognizing other nuances of searching on the internet, such as recognizing when illegal linking schemes are present on websites. So, they are not ancient in certain context, but they definitely are, in the new language recognition department. This brought us back to our discussion about Javascript and RSS feeds.
Javascript is a web markup language that is recognized and read by the user's browser, but not all the time, depending on the set up of the site. Javascripts can also be controlled by the host server in displaying RSS feeds on a website. In either case, it is still not recognized by search engines-search engines cannot read Javascripts.
Therefore, the only benefit a website that is displaying feeds via Javascripts get is user interactivity statistics, which is a component of search analytics. If search spiders, recognize that a particular website displaying RSS feeds via Javascript is being frequent by visitors and those visitors are sticking around for long periods, then it will give credits to that site by ranking it higher than it normally would have without the interactivity.
It is much more difficult to implement RSS content technology using PHP than it is Javascript, but it is worth the effort. Webmasters would have had to learn the PHP markup language, which isn't, easy before they would be able to use it to display feeds. There are many RSS content reader software on the market and there are also many websites that offer free versions.
The PHP to HTML option of displaying feed content is much more search engine-friendly. When the server communicates to the website, it uses the PHP language to do the communicating. The website then responds to the signals from the server by using the HTML markup language, which is what the search spider seas and can recognize.
The RSS feed is then displayed among the HTML codes and tags where the search engine spiders picks them up and deliver them to the search engine directory for archiving. So when search terms corresponding to those key words are entered into the search engine search bar, the search engine displays the archived information to the human searcher.
The search engine therefore perceives the feed content between the HTML codes on a website displaying feeds as belonging to that website. So even though the content or feed is being fed from another site, the search engine thinks that it originates from the website displaying the RSS feed. This is the advantage of using PHP and HTML to display RSS content on a website.
In concluding thoughts, using Javascript for displaying RSS feed content does have some good, but it definitely has its share of drawbacks. Using PHP and HTML to display RSS feeds on the other hand, is obviously the better option; however, it is the most difficult.
