SEO optimization Impact ranking changes in the basic factors

Server performance: In general, the search engine will be a fixed frequency and reasonable time to crawl our site, but if your server at this time the problem, then you can not guarantee the search engine spiders visit your site, which may cause your site's ranking decline.

Competitor's competition: If you get a part of the popular keyword ranking, then in the same industry whether there are competitors are also doing such a word SEO work? If there is, then you have to be careful, because you may face the competition may be more than your SEO method in the site to promote optimization.

Search engine Database Volume impact: In fact, the search engine's crawling, included, ranked by a certain mechanism to run, the search engine database server, he may have your site's data stored in different servers, which means that there may be at a specific time and place your keyword ranking is different.

Second, let your homepage to keep the site first

Often the home page is not the first reason is because the homepage of the update frequency is lower than the inner page, or the inner pages are more concerned than the homepage. Let spiders mistakenly think the home page is not the core. That is, commonly known as "down the right" in fact, as long as add a site map, the importance of the first page set to the highest (1.0), as well as the crawl frequency modified (depending on the situation, do not pursue the more the better.) Otherwise the spider comes in a few times without new things, so will lose confidence, and then properly updated and added outside the chain. can solve this problem.

Third, let the spider Know your website structure

Many people overlook the h1,h2 ... These tags, I also overlooked at the beginning. Until I see my competitors have only h1,h2 these tags, even the basic keywords and description tags are not. But it remains the top position in the field. So I thought about it. Some time ago to hear the individual webmaster said: "Now Baidu on the Keywords,description label less and less value, more attention to site content and user experience." Keyword and description tag will only give Baidu spider a convenient interpretation.

So say h1,h2 ... It can even be used to replace the labels of keywords and description, and can even make a better effect than the former. My h1,h2 to the website ... The suggestion is: the homepage aspect, H1 uses to put the website title, H2 uses the website subtitle, H3 puts the column title, H4 puts the list title.
