SEO (Search Engine Optimization) content is dependent on certain site elements that you need to take cognizance of. Sometimes, overlooking these factors can make all the efforts to get web rankings up, go down the drain. One such site element is the robots.txt file. Search engines while visiting a website, do a content classification. During this process, the search engine robots might pick up obsolete content from a website. Some content might be used on a website for dual-purposes. The search engines might pick up these as well. As a result, websites might be penalized for using duplicate content. Search engines feel, the website is using illegal SEO techniques, when content is duplicated on a website. So what happens is, that the website’s search engine rankings fall drastically.
Using a robots.txt file can control all these things. To put it simply, a robots.txt file is a text file that you put on your website for search engine spider programs to read. You have to put this file in your main directory; otherwise search engine spider programs might miss it. A robots.txt file will enclose all information that has to be excluded from the search engine spider program indexing. By doing this, a website’s content can be preened for public perusal. It also assures confidentiality.
Robots.txt file can be used to take out pages from being indexed by search engines, and displayed as search results on user searches. To exclude page-level content, the Robots Meta tag can be used in the source code of web pages. You can use this Meta tag to specify the content that has to be excluded from the search engine indexes. However, caution has to be exercised, since a small mistake here could also create a fall in the website’s SEO rankings.
So, the above factors can play a key role in enhancing a website’s SEO rankings. By using robots.txt, you can only put content that can easily pull in search results and good SEO rankings. By using content that is rich in SEO keywords, there will be no more obsolete indexing of your web contents.
