For me, fixing crawl and indexing issues had the biggest impact. Once Google could efficiently discover and index the right pages, rankings improved much faster than from speed tweaks alone.

I improved technical errors like broken links and redirect problems this helped me more than small speed changes.

One techniccal fix that resulted in an unexpected boost was cleaning crawl waste. There were way many redundant links, outdated web pages, and poor internal linking structure which made the search engine's job even harder.
With these factors out of the way, the indexation process became much smoother. often times it is the removal of obstacles that results in major techniccal success.

Fixing indexing & crawl issues like no-index tags, bad canonicals & internal linking usually has the biggest impact far more than speed tweaks alone

Fixing crawl/indexation issues (especially removing noindex blocks and improving internal linking) had the biggest impact, leading to the fastest organic traffic gains.

hi Technical aspect :
XML sitemap submitted
Proper robots.txt configuration
No unnecessary no index tags
Canonical tags implemented correctly
Fix crawl errors (404, 5xx, redirect loops)
Orphan pages identified and linked
Pagination handled properly

Improving internal linking had the strongest impact on one of my sites, It helped search engines understand the content better and gave important pages more visibility without creating new backlink's.

A lot of people have already mentioned site speed and internal linking, so I'll throw out another one that often gets overlooked: keeping an eye on your 404 errors. This is especially important for eCommerce websites that are constantly adding, removing, or replacing products. Over time, those missing pages can add up to hundreds or even thousands of 404 errors, and if any of those pages were driving traffic or had valuable backlinks, you could be losing SEO value. Make it a habit to monitor those errors and redirect important pages when appropriate. I'd also make sure your website works just as well on mobile as it does on desktop. Many business owners only review the desktop version during development, but the majority of users now browse on their phones, so a fast, responsive, and functional mobile experience is just as important as anything else you do for SEO.

If I had to prioritize, I'd start with making sure the important pages are being crawled and indexed properly. After that, I'd look at site structure and internal linking so Google can easily understand the content.

Site speed and Core Web Vitals are worth improving too, but in my experience, fixing crawling, indexing, and internal linking has usually had a bigger impact than chasing small speed improvements.

Fixing crawl and indexing issues and cleaning up internal linking the biggest ranking boost much more than chasing tiny Core Web Vitals improvements.

The biggest win for me was fixing crawl depth. Some important pages were buried too deep in the site structure. Bringing them closer to the homepage and improving internal links got them indexed faster and performing better.
