A significant surge in content might cause the site to be perceived as new, which could result in it being temporarily overvalued.

    For example, if the size of your website expands tenfold or more, the search engine might treat it as a brand-new site and begin a reevaluation process.

    What could cause a website to grow so dramatically in size? Common scenarios include:

    • Merging two websites into one,
    • Adding a large volume of new products, such as increasing from 10,000 to 100,000 pages.


    While this isn’t inherently an issue from an SEO perspective, it’s important to note that, like indexing a new site, it may take months for a search engine to reevaluate the expanded website. During this process, search engines will assess:

    • How the quality of the site has evolved with its growth—whether it’s improved or declined,
    • How the expanded website fits within the broader internet ecosystem.

    Because we are discussing rapid and large-scale growth, it’s advisable to implement changes gradually, such as adding products and pages in phases.
