Sitemaps are an important element of search engine optimization (SEO), in order to provide search engines an accurate outline of what content exists on your site. One of our client sites recently outgrew Google's sitemap URL limit. Instead of removing content from the sitemap, we implemented a simple solution of using a sitemap index to reference multiple sitemap files.
Since the beginning of 2012, for one of our clients with a big news website, we recognized a drastic increase in website traffic without an accompanying increase in ad impressions. Under normal conditions, an increase in traffic would be a positive sign; however, in this case it was caused by end user software that turned normal web users into aggressive web crawlers. This essentially created an accidental but consistent distributed DoS (denial of service) attack.
Here, we explain how we identified the cause and mitigated its effects.
A common task in website search engine optimization is to set up Google Webmaster Tools and go through its HTML suggestions. Many of the suggestions center around duplicate content -- pages at different URLs but that have the same HTML title, meta description, body content, and more. This post summarizes a couple of common duplicate content scenarios within an eZ Publish site, and how to solve them.
Many hosting companies will take care of file system and database backups for you. We have a few clients where we have file system backups configured, but database backups have to be handled manually, since the database is "live data". Often we can just configure a cronjob that runs mysqldump so that a database snapshot is stored to a file and thus regularly backed up when the file system backup is run. However, sometimes you have a perfect storm where mysqldump is too heavy for the server (causing severe slowdowns or even crashing some services), even if run in the least intensive way (such as with the --quick flag) and at a low traffic time: partially due to lack of system resources and a large database.
Do you frequently use the Google, Wikipedia, and other search boxes in Firefox, typically in the top right of the window? Ever wanted to add your own for a site that isn't on the directory? Here's a quick and dirty guide to creating your own Firefox search engine plugin, using the api.jquery.com search as an example.
