Algorithms on search engines are complex and intricate. It’s these algorithms that determine where your website ranks on search engines.
Your ranking on search engines determines how much web traffic you’ll receive for a particular result.
However, it can take a search engine upwards of six months to crawl your website after changes come into effect, to determine how changes to your content affect your search rankings.
Overall, a good SEO strategy that factors in the algorithms will take about six months to see the first results followed by 18 months of sustained growth in organic search traffic.
