Recently, Wuhan SEO blog received a friend website reconstruction, the purpose of reconstruction is to get better performance. He used to do is a local industry website in Wuhan, did not know what SEO is. Therefore, the first thing to do is to use the idea of SEO to think about what the new site in the new form. Including SEO thinking to design the structure of the site, arrange the content of the site and read the user's friendliness. However, when the site to be revised, to consider the original site to maintain the existing rankings, especially some important keyword rankings. Search engines are very sensitive to the update of the site, small changes, even if the web to make makeup, dress up, will cause a lot of changes in the rankings.

Website rebuilding has two goals. First, in order to make the website more attractive, keep the update degree. Second, enhance the performance of the site in search. In both of these, we need to take the second objective as the main goal, on this basis to achieve the first. The main reason is because there is no search results there is no ranking, no ranking no one to appreciate. Now let's analyze why?

In fact, every site change must have a threshold to measure the degree of change. This scale, in the search engine year no one can know how to set. Perhaps 5%,10% will not have any significant impact, but over a certain percentage, spiders will re-examine the site.

Because spiders do not look at this site from a human perspective, it is simply a elephant way to experience the site. Previous memories are stored in the form of cache. Spiders every visit to a website to collect information on all aspects of the site and to score, if your site changes drastically, it will be more careful to observe what happened.

So how do you reduce the risk to a greater extent?

First, first determine which old pages in the search engine to get a good ranking. These content already exists in the search engine to have the good rank, uses or the content as far as possible changes.

Second, try not to change the original site structure and the name of the Web page. If the structure and naming are not conducive to search engines, it is necessary to change the first time. Retain the original search engine to adapt to the structure, even if the presentation of the form and content has been changed, search engines can still follow the "original Road" to find a Web page, a faster collection and replace the old memories. My company's game network in Baidu is so, slowly to replace the previous content.

Third, in the new site after the publication of a period of time, continue to retain the old site structure and content, do not immediately delete. In the old site, create the right link to the new Web page and guide the search engine to new places. If the original page is discarded, immediately do a 404 Web page to avoid the search engine encounter a vacuum. Important pages, it is necessary to enable 301 permanent steering to the new website. Next I'm going to test the impact of the 301 shift on a website.

The best way to do this is to use Google's XML sitemap to tell Google that your site is updated.

Five, you need to know that when your site is updating a lot of content, or changing the structure is very intense, the search engine may take more time to observe and analyze your site.

Search engines need to estimate the relevance of your content to the original content, the relevance of links, and how so many new content contributes to and influences the theme of the site. A friend of mine's website Soowan in the past is to write about Wuhan it news website, then got a good ranking, PR value also obtained 4. Later the content into a small game site, search soon included and keep the original structure, but after a period of time, search and the new contents of all removed, until the last month to slowly increase the index amount, look up to six months long. Visible spiders or more intelligent, can distinguish the intention of the webmaster. So you'd better not do it again.
