When you are launching a new website, you can register its domain and start building it without having to worry that search engines like Google will find it before it is ready for public viewing. Many people do not know that the "web robots" that Google and other search engines send throughout the Internet in order to index web sites for inclusion in their search query result pages are designed to check for the existence of a file titled "robots.txt" within the website's domain space. All search engine robots will deliberately ignore visiting any of the website's pages if the webmaster posted the text file and the lines "User-agent: *" and "Disallow: /" are its only contents.
A website that has been put up in an incomplete state will not have to worry about its ranking in search engines' result pages being negatively affected for it because of robots.txt. Even after a completed website removes that file, however, it will still have a hard time getting ranked on search engines in relatively short order even if it makes efficient use of SEO techniques from that point onward. It will take time for any website's SEO to apply itself this way, so in order to see its effects on the site's traffic, sign up for Google Analytics.
If you do not want to resort to paying for an SEO specialist to optimize your website for search engines, you will have to put in months of effort by yourself to publicize your site and get other websites to link back to it, and you will have to use software that gauges keywords by their strength and relevance. Your web pages' title and meta tags need to be optimized, and your keywords and similar phrases need to be strategically incorporated into your website's content without making them appear so many times that search engines will possibly ignore them. Provided that your website is also optimized for display on mobile devices and that you keep on supplying fresh content to its public pages, your website should be ranking up at a steady pace.
