What’s the difference between On page SEO and Off page SEO?

On page SEO refers to optimising individual web pages in order to rank higher and earn more relevant traffic in search engines. This includes optimising content, titles and meta descriptions, as well as improving the internal link structure of a website.

On the other hand, off page SEO is about improving the authority of a website through external links from other websites. Off page activities include building backlinks from high authority sites, social media promotion and much more. Both on-page and off-page SEO are important for achieving better rankings in search engines.

Do SEO tools guarantee a page-one ranking?

No, using SEO tools cannot guarantee that your website will rank on the first page of search engine results. SEO tools are a means to an end, and a lot of effort is required to get your website on the first page of results.

Can I use SEO tools to spy on my competitors?

Yes, some SEO tools come with competitive analysis features that allow you to monitor your competitors’ websites, including their traffic, ranking, and backlink profiles.

However, don’t get too carried away with spying, you also need to put in some work on your own SEO activities.

How long does it take to see results from SEO?

Good SEO is like a fine wine—it gets better with time. It generally takes 3-6 months to start seeing results, but remember, patience is a virtue!
