The term ‘crawl‘ refers to the process by which search engines, like Google, discover new web pages and update their existing listings. This process is essential for ensuring that search engines can provide their users with the most relevant and up-to-date results for their queries.
Crawls are typically carried out by automated software programs known as ‘web crawlers’ or ‘spiders’. These crawlers navigate the web by following links from one page to another, with the goal of discovering and indexing as many pages as possible.
As the crawlers explore the web, they gather information about each page they visit, including its content, the links it contains, and any other relevant metadata. This information is then used to determine the relevance and ranking of the page in search engine results.
The Importance of Crawl in PPC
In the context of pay-per-click (PPC) advertising, crawl is an important factor to consider when optimising campaigns. PPC campaigns rely on the accurate and up-to-date indexing of web pages in order to ensure that ads are being displayed to the right audiences.
If a search engine is unable to crawl a particular page, or if it takes a long time to do so, it may result in the page being ranked poorly in search results. This can have a negative impact on the visibility and effectiveness of PPC campaigns, as ads may not be displayed to as many users as they otherwise might be.
To ensure that PPC campaigns are as effective as possible, it’s important for advertisers to ensure that their web pages are easily crawlable by search engines. This can be achieved through a variety of techniques, including optimising the structure and content of the page, as well as ensuring that it is free from technical issues that may prevent crawlers from accessing it.

Factors That Affect Crawl
There are a number of factors that can influence the crawl rate of a particular web page or site. Some of the most important include:
- Site structure: The way in which a site is structured can have a big impact on its crawlability. A well-organised site with a clear hierarchy and logical navigation is more likely to be crawled effectively than a poorly structured site with a confusing layout.
- Page loading speed: Crawlers are designed to move quickly from one page to another, so if a page takes too long to load, it may be skipped over in favor of faster-loading pages.
- Site performance: If a site is experiencing technical issues, such as server errors or downtime, it may be difficult for crawlers to access and index its pages.
- Link quality: The quality of the links pointing to a particular page or site can also influence its crawl rate. Pages with high-quality links from reputable sources are more likely to be crawled frequently than those with low-quality or spammy links.
- Site content: The content of a site can also play a role in its crawl rate. Pages with high-quality, relevant, and regularly updated content are more likely to be crawled frequently than those with thin or outdated content.
Tips for Improving Crawl
There are a number of steps that PPC advertisers and marketers can take to improve the crawl rate of their pages and sites:
- Ensure that your site is well-organised and easy to navigate: A clear hierarchy and logical navigation structure can help crawlers more easily discover and index your pages.
- Make sure that your pages load quickly: Fast-loading pages are more likely to be crawled frequently, as crawlers are designed to move quickly from one page to another. You can improve your page loading speed by optimising images, minifying code, and using a content delivery network (CDN).
- Fix any technical issues: If your site is experiencing technical issues, such as server errors or downtime, it may be difficult for crawlers to access and index your pages. Make sure to regularly check for and resolve any technical issues that may be affecting your site’s crawl rate.
- Improve the quality of your links: High-quality links from reputable sources can help improve your crawl rate. Avoid low-quality or spammy links, as they may actually harm your crawl rate.
- Regularly update your content: Pages with high-quality, relevant, and regularly updated content are more likely to be crawled frequently. Make sure to keep your content fresh and relevant to help improve your crawl rate.
- Use sitemaps: Sitemaps are files that list all of the pages on your site and provide additional information about each page, such as its relevance and when it was last updated. Submitting a sitemap to search engines can help them more easily discover and crawl your pages.
Frequently Asked Questions
Is crawl the same thing as indexing?
Not exactly. Crawl refers to the process by which search engines discover new web pages and update their existing listings. Indexing, on the other hand, refers to the process of storing and organising the information gathered during the crawl process. After a page has been crawled, its information is added to the search engine’s index, where it can be used to determine the relevance and ranking of the page in search results.
How often do search engines crawl websites?
The frequency with which search engines crawl websites can vary. Some sites may be crawled multiple times per day, while others may only be crawled once a month or even less frequently. The crawl rate of a particular site is determined by a variety of factors, including the quality and relevance of its content, the structure of the site, and the number and quality of links pointing to it.
Can I influence the crawl rate of my site?
Yes, there are a number of steps that you can take to improve the crawl rate of your site. These include ensuring that your site is well-organised and easy to navigate, making sure that your pages load quickly, fixing any technical issues, improving the quality of your links, regularly updating your content, and using sitemaps.
How do I know if my site is being crawled effectively?
There are a number of tools that you can use to track the crawl rate of your site, such as Google Search Console and Bing Webmaster Tools. These tools provide information about how often your site is being crawled, as well as any crawl errors that may be affecting its performance.
