Frequently Asked Questions
Organic SEO (Search Engine Optimisation) refers to the process of improving your website’s ranking on search engine results pages (SERPs) through non-paid strategies. It involves optimising your site’s content, structure, and links to increase its visibility and drive more organic traffic. Unlike paid ads, organic SEO focuses on long-term results through quality content and technical improvements.
Local SEO focuses on improving a business’s visibility in local search results, often targeting location-based queries. It involves optimising your Google My Business profile, local citations, and localised content. Organic SEO, on the other hand, aims to improve rankings on a broader scale and is not limited to a specific geographical area, focusing on website optimisation to rank for a variety of keywords globally or regionally.
Organic SEO results can take anywhere from 3 to 6 months to show significant improvements, depending on factors such as website age, competition, and the effectiveness of your SEO strategy. Unlike paid ads, which offer immediate results, organic SEO is a long-term investment that focuses on sustainable growth over time.
Organic SEO focuses on improving your website’s ranking through non-paid techniques like content optimisation, link building, and technical SEO. Google Ads, however, is a paid advertising platform where you bid for ad placements based on targeted keywords. Organic SEO provides long-term results, while Google Ads offers immediate visibility but stops once you stop paying.
Organic SEO is crucial for building long-term visibility, credibility, and trust with your audience. It helps drive consistent, targeted traffic without ongoing costs associated with paid advertising. By ranking higher on search engines, your business becomes more visible to potential customers, ultimately leading to increased conversions and sustainable growth.
