In general, a Web site in search engines have a good long-term ranking, relying on the webmaster long-term constantly in the SEO efforts. Maybe your site architecture is more fixed, but no site can never be upgraded, the reason for the upgrade may be to make the user experience better, or to the search engine more friendly. No matter what the reason, the general website to a larger degree of revision, will be the site's SEO negative impact, light in the search engine to reduce a certain ranking, heavy is k even directly pulled hair pulled clean. Here to talk about their own experience, to help you reduce the revision of the site to the negative impact of SEO.

First, in order not to affect the user experience, do not directly modify the original page

This is easier to understand, when you modify the page, there are still a lot of users online, in the process of modification to produce a variety of errors is unavoidable, this will cause a very poor user experience, should be avoided, and if the search engine spiders this time to crawl your site, Page errors can also affect the SEO. Should do is, the page to be modified to copy one, changed into a people do not know the name, such as the homepage index.php, we can copy and then changed to index2.php, such as modified the perfect, used to replace the original index.php good.

Second, treat the change of page markup with caution

This is particularly important, we all know that the search engine on the page some special tags, such as h1,h2,alt,title,strong and other indicators are more sensitive, and we are in the revision of the site, often may change the number of these tags on a page, For example, the title of the navigation module may need to use B or fervent to emphasize the bold, this is good for the user experience, but the search engine is not necessarily so think, it saw a page suddenly increased b,strong and other markers, will suspect you are deliberately targeted at search engine seo, It is very possible for you to have the right to fall. So be sure to note that the revised page, do not increase the number of B tags, for the image of the alt mark also do not increase too much, can be followed by gradual, sudden increase in too much, the impact on the SEO is great.

Third, the revision of the navigation module text

The so-called navigation module text is the search engine spiders and users in the current page and the next level of the page, such as A5 navigation is so, home > Promotion > content page, which day you want to the website revision, thought the navigation text actually can increase inside link, put "homepage" Changed to your homepage keyword to increase the chain link, such as "Webmaster Network > Network Promotion > Content", perhaps you think this change is very small, but in search engine view, your this revision influence is very huge. To know, a more mature web site generally have thousands of or even tens of thousands of of the page, made this change, it is equal to your home page increased thousands of tens of thousands of chain link, so suddenly a large number of links, search engines do not punish you to blame it. So as little as possible to change here, even if you want to change the navigation, you must manually change, some part of the time to change, do not change all of a sudden. Of course, if your site page is less, you can get rid of all at once, that impact is not big.

Four, static dynamic pages

We all know that dynamic page for users there is no harm, but search engine spiders difficult to crawl dynamic page, so in order to SEO, many webmaster will consider the previous dynamic page all static. However, the site was previously included in the dynamic page, all static, is equivalent to the site is included in the URL of the page all modified, by the search engine down the right, reduce the inclusion that is inevitable, the recommended method is not to change all dynamic pages to static pages, but let two types of pages coexist, and then do 301 transfer, Move the dynamic page to the corresponding static page, such as search engine static page after the record, and then remove the dynamic page.

This time to share the experience is the above, I have been the site revised down the right of the suffering, so to share their experience to everyone, I hope we can learn from this aspect of the detour.
