one thing that has worked better than expected for me is updating old content instead of constantly publishing new articles. Improving outdated posts., adding fresh information and targeting related keywords has helped boost rankings much faster than I expected.

In fact, updating existing pages can be more effective than publishing new ones since those pages may already have some ranking power.
I tend to review the number of impressions and searches first, and then I update pages that have larger gaps.

do post content regularly and update old content with valuable information also build links

Refreshing older pages has worked better than I expected. Sometimes improving content that already gets impressions brings better results than publishing new articles from scratch.

Is it still possible to buy links?

One thing I find interesting is how much difference a proper content refresh can make. Instead of publishing new articles every week, it makes sense to revisit pages that are already getting impressions but aren't bringing much traffic. Sometimes, the content is close to ranking well and just needs a better answer to the search query, a clearer structure, or more relevant internal links. I'd check those pages first before starting something new.
