WordPress creates a robots.txt by default and serves it to website visitors. Companies like Google use bots (software) to scan the internet for sites automatically and to read the contents of those sites.
If the first thing a visitor or a search engine’s bot sees when viewing your website is an error page, then you have a severe problem. The visitor will leave, it’s uncommon for someone looking at a site to fight past the error.
WordPress is an incredible system to build your business website, niche blogs, personal sites/blogs, even some services. It’s friendliness to SEO, plus its immense coding and designing community make WordPress the best content management system.
A trap SEO professionals and their clients can fall into is focusing too much on getting the number one spot on Google. It’s easy to see how it happens: we monitor our progress by watching websites move up the rankings, with the top slot marking a natural finish line.
