Web pages are supposed to load as soon as people click on it. No one has time to spare and hence, make your website worth theirs. A good network connection goes a long way and so does SEO optimization.
Search Engine Promotion
Robots in search engines crawl to your website and discover content on it i.e. indirect promotion. This leads to traffic that is amazing for the business. With the great internal linking structure, your website will be divided into important parts for later use.
Dead Link Riddance
As mentioned above, time is money.
If your site link is non-existent and leads the visitor to an error page, it can count as bad publicity for your business. Not only will you lose potential customers, existing ones might have trust issues.
No Duplicates
More often than not, duplicity of content is seen on most of the websites. Though you enhance your listing, the search engine can confuse itself in order to rank one higher than the other. Even if you do have duplicate content, using some functions might help you rank the one of your choice higher.
Optimization & Security
Making your website a safe place online for users is a requirement. You can implement this by the use of HTTPS.
This does not only prove your diligence but also capability in protection of sensitive data.
