Upon launch of your website it won't automatically show in search engines (Google, Bing etc.). You need to submit your website to each individual search engine so they can analyse the content, and then rank it among other websites based on your content.
To improve your website position in search engines you will need to work on the following:
Google and other search engines will not show your website in the top search results to begin with. You need to have high quality content that is clear, concise, and easy to read.
Headings, titles, content etc. should be written the way you would expect to search for them. When competing with other websites it is best to match the search terms as closely as possible.
A great tool for checking content structure is HemingwayApp.
Your website will rank higher in search engines if it has more links (referrals) to your website. This can be achieved by sharing your website on social media (Facebook, Instagram etc.). Getting your website reviewed by people, and other websites is also a useful way to get referrals.
Another good way of get referrals is to create a Google Business Profile. When your profile starts to gain positive reviews search engines will give your website better search rankings.
A common myth is that domain age improves SEO which is now mostly incorrect. Website age does contribute to better rankings. It takes time improving search engine rankings, writing quality content, and getting referrals. Your website won't initially show in the top results but it doesn't take long to improve rankings.
Many SEO tools claim they can improve website rankings, but the above are the biggest factors that can influence this. Good coding and website structure is already taken care of by Meddle. The only areas you need to focus on are content and referrals. Changes will not happen instantly. If you produce consistent high quality content your website rankings will improve over time.
