Search Engine Optimization is where the digital realm meets the art and science of climbing the ranks in search engine results. Here's everything you need to know, from the fundamentals to the advanced.

Frequently asked questions

What are the main types of SEO?

On-page SEO covers what sits on the page itself, including content, headings and internal links. Off-page SEO covers signals earned elsewhere, mainly links and mentions. Technical SEO covers whether search engines can crawl, render and index the site at all. All three have to work for any of them to pay off.

How long does SEO take to work?

On an established site, meaningful movement usually appears in month three or four, with compounding gains from month six. A new domain takes longer because there is no crawl history or authority to build on. Anyone quoting a shorter timeline is either working on very low-competition terms or is not being straight with you.

What is the difference between white hat and black hat SEO?

White hat SEO earns rankings through content quality, technical soundness and genuine authority. Black hat SEO manipulates signals through tactics such as bought links, cloaking or scaled thin content. Black hat can work briefly, but the recovery cost after an algorithm update almost always exceeds whatever was gained.

Which SEO metrics actually matter?

Organic sessions to money pages, keyword position for commercially relevant terms, conversion rate from organic and the pipeline value those conversions produce. Impressions, domain rating and total keyword count are diagnostic signals, not outcomes, and reporting that leads with them is usually hiding the absence of the ones that count.
