through the 500s, status codes fall into the accompanying
Classifications:

However, the server did not complete the request.
• 400s – Client Side error. Request was sent by the client, page turns out
to be invalid.

is necessary to complete it.

ought to happen whenever the server can’t locate a coordinating page
request. Periodically, web- masters will display a text 404 error however

2. 503 Status Code:

transitory over- loading or server maintenance. The 503 ought to be
utilized at whatever point there is an interim blackout (for instance, if the
server needs to descend for a brief period for maintenance). This
guarantees the engines know get back soon in light of the fact that the
page/site is down for a brief span.

5. 3. 302 Found Status Code:

alternate location, yet the requester keeps on utilizing the initial location for
requests in future. This methodology is not prescribed. It is not a compelling

redirect as an interim one and not give it the link juice (ranking power)
capacities of 301 redirects.
