How many backlinks are safe for SEO?
There is no specific limit on the number of backlinks that are considered safe for SEO, as it depends on your niche competition and the choice of marketing channels preferred.
The more relevant and authoritative the backlink is, the safer it is for SEO and overall good for your website's search engine rankings. Remember, focus on quality links over quantity; a few high-quality, relevant backlinks are more beneficial than many low-quality ones.
Make sure the backlinks are not spammy or gained from black-hat SEO tactics that likely harm the SEO rankings of your website.
