Website Scraper Analysis Filters in Website Scan
Website scan analysis filters (also known as crawler filters) help you define which pages you want analyzed for content and links during website scans in our website scraper.
We have a video tutorial:
Even though the video demonstration uses TechSEO360
some of it is also applicable for users of A1 Website Scraper
Analysis filters determines which pages have their content analyzed for links and other data.
You can use analysis filters
instead or in conjunction with
Exclude URLs in both analysis filters and output filters
crawl time, HTTP requests and memory usage.
Note: If an URL is only linked from pages that are not analyzed due to filters, it will not be found during the website scan.
For changes in analysis filters to take effect, you will need to crawl your website again.
URLs with file extensions not
found in the list will not
be analyzed durng website scan.
If you remove all file extensions in the list, the file extension list filtering accepts all files.
Excluding URLs that fully or partially match a text string
or regular expression pattern
from being analyzed is often a good way to limit the crawl.
- blogs matches relative paths that contain "blogs".
- @ matches relative paths that contain "@".
- ? matches relative paths that contain "?".
- :s matches relative paths that start with "s" such as http://www.microsystools.com/services/ and http://www.microsystools.com/shop/.
- :blogs/ matches relative paths that start with "blogs/" such as http://www.microsystools.com/blogs/.
- :blogs/* matches relative paths excluding itself that start with "blogs/" such as http://www.microsystools.com/blogs/sitemap-generator/.
- Regular expression:
- ::blog(s?)/ matches relative paths with regex such as http://www.microsystools.com/blogs/ and http://www.microsystools.com/blog/.
- ::blogs/(2007|2008)/ matches relative paths with regex such as http://www.microsystools.com/blogs/2007/ and http://www.microsystools.com/blogs/2008/.
- ::blogs/.*?keyword matches relative paths with regex such as http://www.microsystools.com/blogs/category/products/a1-keyword-research/.
- ::^$ matches the empty relative path (i.e. the root) with regex such as http://www.microsystools.com/.
From above examples it can be seen that:
- : alone = special match.
- : at start = paths match.
- : at start and * at end = makes paths into subpaths match.
- :: at start = regular expression match.
- None of above, normal string text match.
