Does the SEO of your entire website suffer from the deletion of pages and posts? Not always.
However, depending on how you handle the circumstance, it can have certain disadvantages.
It’s actually advisable to delete pages from your website. Your overall SEO efforts may suffer as a result of pointless websites that dominate the SERPs. Search engine algorithms are actively tracking many more complex parameters. When worthless web pages surface on the SERPs, it really lowers your site’s total CTR and CTR for each individual page.
By directing Google to low-quality pages, you can also be squandering your crawl money. “Low Quality” is a comprehensive word, but anything as simple as a lack of internal connections on a page might indicate that Google doesn’t successfully scan all your information.
The deletion of pages, however, can also harm your SEO! You risk losing Page A’s ranks if you remove Page B even though Page A benefits from the link equity it receives from Page B. This might happen if Page B has little traffic or if its content is out-of-date.
Nothing might occur; it’s possible
It will be beneficial for your website if you go through and eliminate any pages or articles that have no traffic, no rankings, no inbound links, and no value in general. It’s unclear, though, if this will actually have a good impact.
If you remove those pages, your rankings and traffic could improve. Those pages might be hurting you. However, it’s conceivable that they were simply pointless sites with no sound or destructive impact, meaning that removing them will have no effect either.
Having said that, you will have a greater understanding of what is occurring on your website even if there is no impact on visitors. Old material may be updated, and you can make use of it to correct any mistakes, add new data, including new media, and add more textual content.
