The language of coding is varied and contains many characters that may be foreign to search engine robots. Because these robots need guidance when indexing a website, it may become confused or lose the path it was following through your website if it encounters coding with foreign characters or complicated strings.
It is therefore essential to check coding for characters that could be confusing to these crawlers. Coding should be cleaned up and where possible simplified into its easiest form. There shouldn’t be a lot of variants and it should be fluent and easy to follow. This will prevent the search engine robot form getting lost – and dramatically increase your SEO results.
