Well surely it does affect the pages with crawl errors. It simply means that google's spider cannot reach your page (at given time or all the time), so it cannot index/reindex it, hence if not indexed at all you cannot expect any rankings... Just check each and every error and fix it. It could be some temporary problem with your server being down for example when they tried to crawl it.
Hi Every 2 days or 10 days or 15 days google robot will crawl the website, it will check any thing updated in website means it will be updated in Google.It doesn't effect ranking
Hello, It surely affect on keywords as if your pages are not crawled timely than any updates on pages are not crawled by the Google bot. Thanks
It's the software they use to visit sites/pages all across the web, see what's there and put it into a databse (an ever-changing one) in order to display the current results for particular searches. Imagine it as a snapshot of your current page content. However, the ranking factors are quite more, starting with the backlinks to that page/site. Just fix the crawl errors for a start Maybe you have some invalid/broken links/URLs? Also such message will appear if someone linked to your site in an incorrect way (to an URL that doesn't exist). If that is the case just ignore it...
means you wanna say that google spider scan our website top to bottom and check the data , am i right ?
Yes, it scans it (as well as any other search engine) in order to find out what info is out there, classify it/rank it and display it as a seach result for certain terms (keywords). Also it scans/indexes only where you are allowing it to do so - have a look around DP or anywhere about robots meta tag. As I said above, the rankings do not depend only on the content itself, but it is a must start...otherwise what would you offer to your visitors?
Very well answered i really appreciate you. I think Cristina can now understand what if Google Spider is all about.
No, crawl errors do not affect rankings if they are small in number. They are only meant to improve user experience.
Meta tags like title and description tells the search engine bots what your website is all about. It also serve as your snippets in results page.
Yes it will effect will take you to down whenever a searcher search in google seo start from there google do very fast here if you are indexed in google data base only after ur possibility to be on top. do proper crawling to google robots if u ain't than hire someone to do for you
