SEO or Search Engine Optimisation, is the practice of increasing your ranking on search engines in order for you to be found more easily on the relevant keyword terms people search.

This is very important as people are likely to only find what they’re looking for in the first page of the search results.

There are many aspects to SEO but the main thing you need to know is that its purpose is to increase the amount of traffic and quality of traffic going into your website organically.

Why should you consider engaging an SEO agency?

SEO is the equivalent of increasing foot traffic into physical stores for your digital store or website through organic search results.

In the post-Covid age where digital storefronts are increasing in importance, SEO is paramount for your long-term business growth as advertising budgets are limited and increasingly competitive.

SEO allows you to maintain a strong internet presence for people searching for similar services or products or even information you provide on your site. After all, the best store with great products or services is pointless if it’s in a desolate location without any traffic - and this is the same for your website as well!

There are seven main aspects that goes into increasing your SEO:

  1. Accessibility to crawlers which allows search engines to index your website
  2. Quality content that is relevant and answers the searcher’s question
  3. Keyword optimized to match common search queries and search engine’s algorithms
  4. Website experience which
  5. Link building, citations and shares which increases trust rankings
  6. Relevant URL, title and description which attracts more clicks
  7. Structured mark-up data which enables search engines to prioritise your page for relevant searches

It’s a mix of both technical aspects and good content marketing which can be difficult to get right if you are unfamiliar with it. Hence we highly recommend engaging a good SEO agency to assist you with getting this crucial aspect of your business growth right.
