London: UK Hub for SEO and Digital Marketing

London has long been regarded as the hub of SEO and Digital Marketing in the UK. With dozens of SEO (and other web-tech) businesses sprouting up in the capital, London is gaining worldwide recognition for digital services. The competitiveness of the SEO and digital marketing hub in London means that agencies need to work harder in order to stand out. Competitiveness breeds innovation and creativity, which is a good thing going forward.

Because London is so packed with SEO and digital marketing agencies, it’s likely to be a hot-spot of new trends and developments in SEO in 2019. We’ve highlighted some of the trends we’re expecting to explode in London in the next twelve months.

1) Video Marketing

In 2019, video content is expected to overtake written content, which is going to be a huge shift both for businesses and SEO agencies. SEO agencies are used to providing written, SEO focused, content for their clients, but video content is a different kind of challenge. People are more pressed for time than ever, and video offers a way of providing information in a more engaging, easier to digest manner.

2) Voice Search Revolution

As Salt Agency are already anticipating, voice searching is going to change the playing field for SEO in 2019. It’s going to impact on keyword research and optimisation. It may also mean that businesses have to overhaul their content and keyword strategy to maintain their rankings. Conversational keywords are going to be a big part of this, and it’s going to be more important than ever to understand your audience and the way they search.

3) Mobile First Indexing

With 63.4% of web searches being conducted on mobile devices, it’s no wonder that Google is focusing on the mobile first indexing strategy. This is going to change the way on-site optimisation is done in 2019, with a focus on optimising sites for mobile devices before desktops. Techniques such as AMP (Accelerated Mobile Pages) are going to be a big part of this.

4) Long-form Content

This isn’t a particularly new thing, but it’s becoming increasingly important. With so much competition for businesses online, visitors and potential customers are demanding more value from businesses. There’s a greater expectation for long-form content that is well structured and engaging. This isn’t about adding extra words to existing content – the demand is for new, fresh, valuable content. Be prepared to deliver this kind of content if you want to get ahead in 2019.

5) Amazon Search

Kent Lewis from Anvil has predicted that Amazon search is going to be the biggest SEO trend in 2019. The popularity of Amazon has continued to rise, so much so that 56% of customers start their searching based on products on Amazon. It’s a dramatic change in search habits, and there’s even some suggestion that Amazon could be the new Google. Because Amazon allows visitors to view reviews and offers suggested similar items, it’s a less time-consuming means of finding what you’re looking for – and consumers love anything that saves them time.

The rise of Amazon search means that in terms of SEO, businesses are going to have to look at keyword and item description optimisation. It will also be important to better understand consumer intent to get ahead of the competition.

Keeping Up With Developments

For both businesses and agencies, keeping abreast of the changing landscape of SEO and digital marketing can be a challenge. In the case of SEO agencies, though, keeping up with developments is something they’re always focusing on, meaning you can trust them to give you the best possible results. Even with the changes we’re expecting in 2019, a good SEO agency can make sure you rank up, not down.
