A decade is a useful time frame for investing in exchange traded funds (ETFs).

It is long enough for powerful themes to develop, but also long enough for short-term market noise to fade in importance.

That makes it worth focusing on ETFs with clear strategies, broad opportunity sets, and exposure to areas of the market that can keep growing over time.

Here are three ASX ETFs that could be worth buying and holding for the next 10 years.

VanEck Morningstar Wide Moat ETF (ASX: MOAT)

The first ASX ETF to look at is the VanEck Morningstar Wide Moat ETF.

This fund is built around companies that have durable competitive advantages. That might come from strong brands, cost advantages, network effects, patents, or customer switching costs.

The extra layer is valuation. This ETF does not simply buy quality businesses at any price. It aims to hold companies that are trading at attractive levels relative to analysts' assessment of fair value.

For investors who want exposure to quality US companies with a valuation discipline, the VanEck Morningstar Wide Moat ETF offers an easy way to do it.

Betashares Global Robotics and Artificial Intelligence ETF (ASX: RBTZ)

Another ASX ETF that could be a strong performer over the next decade is the Betashares Global Robotics and Artificial Intelligence ETF.

Automation is becoming more important across factories, hospitals, warehouses, energy systems, and logistics networks. It is being driven by labour shortages, rising costs, and the need for greater efficiency.

This bodes well for the Betashares Global Robotics and Artificial Intelligence ETF. That's because it provides exposure to companies involved in robotics, artificial intelligence, automation, and related technologies. It was recently recommended by analysts at Betashares.

Betashares S&P/ASX Australian Technology ETF (ASX: ATEC)

A third ASX ETF worth considering is the Betashares S&P/ASX Australian Technology ETF.

It gives investors access to the local technology sector, which is very different from the old image of the ASX as just banks and miners.

The fund holds Australian technology companies involved in software, digital platforms, data centres, payments, and healthcare technology. This includes Xero Ltd (ASX: XRO), NextDC Ltd (ASX: NXT), and WiseTech Global Ltd (ASX: WTC).

And with many tech shares, as well as this ASX ETF, down heavily over the past 12 months, now could be a good time to consider a long-term position in the fund. It was also recently recommended by the team at Betashares.
