Many webmaster reflection, according to the search engine optimization ideas will be the site redesign, the site is included on the decline, this is why?
Never change the design unless you have to.
This is true regardless of the part of the change site. When the site has no serious errors, the site keyword ranking also hi Ah yes, or do not make large-scale changes to the site, but can be part of the optimization.
Never change the URL
Some webmasters in the redesign of the Web site, the original site directory name file name, along with the URL has also made changes, just Gaga column content on the line, the original Web page URL has changed, the search engine will use this as a new Web page, such practices not only led to the site's fall, and the new page of the site will also be included in a period of time, there is a point is that the chain also lost its due role.
New page increase cannot be too fast
High-quality original content and valuable content, has always been the topic of the same, whether the column or the speed of the page, the same to control. For example, the ratio of new pages to the site, the current site has 1000 pages, a few days to add a 50 pages, it can, but if a sudden increase of more than 1000 pages, this may be considered garbage.
Even Microsoft's Web site suddenly changed the URL of the blog is considered to be a lot of new pages is the same.
Optimize the speed of the Web page should also be controlled, do not suddenly make every page seo. Just like the title, keyword, link text and so did not optimize, suddenly become quite good optimization, such effect is often the opposite, if added please slowly add in.
301 redirect
When you modify the URL, you can change the original URL to a new URL. These old URLs in the search engine database will also be maintained for a period of time, search will still be searched, whether 301 is the search engine or the user or the site itself, are good, link transmission PR is also good.
