Crawler Problems
The first thing to tackle with your friends in your web development team should be your key crawler issues. These issues include 400-level and 500-level status errors .
A 400-level error means that the content can't be found cambodia mobile database or is gone entirely, while a 500-level error indicates a problem with the server.
As SEOs, our worst nightmare is to discover that a high-value, high-traffic page is returning 400- or 500-level errors. Users who click on an error page won’t wait for the error to be fixed—at best, they’ll try to find what they’re looking for elsewhere on your site. At worst, they’ll head to your competitor’s page.
It should be fairly simple to explain to your developers why this is important - these errors can make a page completely inaccessible to site visitors. The web developers on your team spend long hours creating and maintaining your site; they wouldn't want that hard work to go to waste.
From the developer's perspective
Critical issues on important pages should be avoided at all costs. Part of prevention lies in understanding why the problem occurred in the first place and how you can support your developer in the future. After discovering what happened, work with them to develop a plan to keep you informed of any major site changes that might occur and to provide them with support. Do you have a list of high-value pages? Can you help prioritize them? Ask your developer how you can best help and foster a positive working relationship even when urgent errors occur.
