方法一 
购买插件opencart seo pack pro 
该插件很强大很贵。请自行搜索该资料。 

方法二 
Opencart在开启伪静态功能之后（更改htaccess.txt为.htaccess，在catagory和产品SEO处添加相应的伪静态文字），添加的产品页面和分类页面都可以实现静态化效果，其他页面需要以下方法实现 
编辑catalog/controller/common/seo_url.php 
 

foreach ($data as $key => $value) { 
if (isset($data['route'])) { 
if (($data['route'] == 'product/product' && $key == 'product_id') || (($data['route'] == 'product/manufacturer/info' || $data['route'] == 'product/product') && $key == 'manufacturer_id') || ($data['route'] == 'information/information' && $key == 'information_id')) { 
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE `query` = '" . $this->db->escape($key . '=' . (int)$value) . "'"); 

if ($query->num_rows) { 
$url .= '/' . $query->row['keyword']; 

unset($data[$key]); 
} 
} elseif ($key == 'path') { 
$categories = explode('_', $value); 

foreach ($categories as $category) { 
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE `query` = 'category_id=" . (int)$category . "'"); 

if ($query->num_rows) { 
$url .= '/' . $query->row['keyword']; 
} 
} 

unset($data[$key]); 

}

这里添加下列代码！！！！！！！！！！！！ 

} 
} 
if ($url) { 
unset($data['route']); 

$query = ''; 

if ($data) { 
foreach ($data as $key => $value) { 
$query .= '&' . $key . '=' . $value; 
} 

if ($query) { 
$query = '?' . trim($query, '&'); 
} 
} 

return $url_info['scheme'] . '://' . $url_info['host'] . (isset($url_info['port']) ? ':' . $url_info['port'] : '') . str_replace('/index.php', '', $url_info['path']) . $url . $query; 
} else { 
return $link; 
} 
}
} 
?> 

需要添加的代码： 
 

if ($key == 'route') { 
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE `query` = '" . $this->db->escape($value) . "'"); 

if ($query->num_rows) { 
$url .= '/' . $query->row['keyword']; 

unset($data[$key]); 
} 
} 

然后在数据库phpmyadmin里SQL-运行 SQL 查询-执行 (如执行错误,请检查url_alias名称是否有前缀，例：oc_url_alias，请在自行添加前缀)/ 或找到url_alias手动输入
